Not long ago that every homeowner installed a wired security system, that’s how much our technology has grown. But, now technology has improved and therefore things have improved including better ways to monitor your security system. Wireless Monitoring can make things handier for you.
The security of your loved ones alongside yours should be your greatest investment. You shouldn’t risk your hard-earned properties and asset yet you can protect the assets using monitoring systems.
Different Reasons For Installation Of Wireless Monitoring System
1. Easy installation
Do you remember how you used to install a wired monitoring system? You probably had to move your furniture and wall painting to fix the wires and cameras. But, wireless tether doesn’t require you to install wires around the house. You fix it at the door, window or whatever place you choose.
2. Safe from damage
Suppose you are renovating your house, there is a high possibility you will accidentally cut off a wired monitoring system. But, if you install a wireless monitor system, you eliminate the possibility of cutting off the wires. Also, your kids could be playing in the room and when they come across the wires, they play using them and accidentally disconnect the camera and control system.
3. Secure
Of course, any monitoring system is meant to look out for your assets and your family. But, what if you have installed a wired system? A burglar will know there is a security system and therefore will try to disconnect before trying to break in. however, the awireless monitoring system has no such issues. You can’t tell if the home is secured or not, but as the owner of the property, you will see records of what happened during the day and any break-in.
4. Ease of expanding the monitoring system
You can add a camera or a sensor when the need arises. Suppose your kids are growing, they are curious and eager to learn.so they will walk around trying to open cabinets and other electronics. In that case, adding sensors becomes necessary so that you protect the kids.
Additionally, if you need to put an extra sensor outside the house, you can easily do it without incurring wiring cost and time.
5. Convenient communication options
Awireless monitoring system uses WIFI and cellular network enabling the system to communicate even during storms and hurricanes. Therefore, if there is an alert from your house, you get informed through your cellular phone.
6. Portability
If you decide to move houses, you can carry your wireless security network with you as long as you are the one who installed it. The advantage of it is that you will still use the wireless monitoring system in the new house.
7. Smart home look
A wired monitoring system is outdated but a few are still using it. Nonetheless, if you wish to look modern, you should consider a wireless system that offers an excellent security system and at the same moment looks modern and smart. Wireless Monitoring can make things easier for you.
With the continuous growth of insecurities case, it is important to take precautions against insecurity. Therefore, consider installing a wireless system that will conveniently serve your needs. In fact, you can incorporate a smoke detector.

In machine design, the role of a sensor is paramount in converting any physical property into an analogue signal which facilitates automation. Machine automation is responsible for the industrial revolution that bolstered economies around the world. Different physical properties require the interpretation of a sensor such as distance, position, temperature, and liquid flow. This article aims to describe each sub-category of sensors according to the property converted.
Reason For Using The Machine Automation Sensors
There are different reasons for using the machine automation sensors that you need to take care off while you want to improve your learning process.
Position sensing:
Detecting the position of an object is possible using different types of sensors specifically measuring linear or angular motion. Encoders, potentiometers, and linear transducers are some of the preferred methods of sensing linear displacement. These devices are compatible with different types of machine assembly. Linear sensors used in rugged industrial applications commonly use a non-contact inductive technology to reduce the effect of friction and wear and tear.
Distance sensing:
Distance sensors can measure the rough distance and often function as a “within range” detecting device. Some distance sensors are programmable such that you can identify the distance of a target object even at an approximate location.
Photoelectric sensors which use light in sensing distance can also work as a distance transmitter. A photoelectric transmitter can detect a distance range of between less than 5 mm to more than 10 m. The resolution is better at short range, but even if the resolution quality decreases at a more extended measurement range, it is still good enough for most machine automation applications.
Speed sensing:
Hall-effect, photoelectric, and inductive sensors are commonly used to sense speed and location. The preferred output is usually a train of digital pulses. A speed switch is typically used for machine automation in monitoring the speed of rotating shafts and identifying whether it is turning too fast or too slow; hence creating problems with the process. As a control mechanism, a sensor signals when the machine is running too fast so that it can automatically shut off.
Fluid flow sensing:
A fluid flow indicator is a sensor used explicitly in measuring the flow rate of liquid or gas. A typical flow sensor consists of a paddle wheel or a float. Some practical applications of a fluid flow sensor include water monitoring in wastewater processing plants and flow indication in HVAC systems.
In most applications using a flow sensor, the sensor can provide either a digital or analogue output. Although there are several ways to measure liquid flow, one that works to detect differential pressure produces the most precise measurements and fastest response time.
Temperature sensing:
Sensors used in monitoring temperature come in a wide range of configurations suited for different applications. Sensing changes in temperature in machine automation is essential. It helps determine when a machine overheats, and to maintain the optimal setting for the device to work correctly. Examples of uses for temperature sensors include boilers, large motors, and compressors. Aside from the temperature sensor, switches are also included in the configuration to aid with temperature control and monitoring.

A safety valve is one of the important mechanical devices used in several industrial applications to protect systems from overpressure. Excess pressure build-up in the system can cause explosions, fires, and damages to critical components and products.
Safety valves are designed to stop these problems by reducing or removing excess pressure from the system. They are specially designed to be actuated by the fluid being controlled; hence, it works when pneumatic or electronic safety controls fail.
Below, we have covered more about safety valves: types, working principles, applications, selection criteria, and everything in between.
Safety Valve Working Principle
The general working mechanism of safety is simple. When the pressure of a system exceeds the maximum allowable working pressure (MWAP), safety valves quickly open to remove the excess pressure before it even builds up. These valves are fast-acting, and they open fully until the system pressure comes back to normal.
Most safety valves have a smaller inlet port and a larger discharge outlet. This ensures that any overpressure can be quickly corrected without damaging the sensitive machine parts. The detailed working principle of safety valves from opening to closing depends on the design and application of the valve. We've highlighted more on this below.
Types of Safety Valves and Use Cases
There are three main types of safety valves. These are:
Spring-loaded safety valves
Pilot-operated safety valves
Safety valves with balanced bellows
a. Spring-loaded Safety Valves
This is one of the most common types where the valve is held closed by a spring, and the balance between the input force and the spring force determines the closing and opening of the valve.
Most spring-loaded valves used in everyday applications come with a flat poppet valve, but those designed for specific liquids and gases come with varying valve shapes. Some even come with a lifting chamber that provides more lift, reducing the time it takes to eliminate the excess pressure in a system.
Spring-loaded valves for vapor and gases often open before the MWAP is reached, and the valve is lifted at least 50% at the MWAP.
The problem with this type is increased backpressure that interferes with the safety of the valve. Backpressure is defined as the pressure that builds upon the outlet of the safety valve as the fluid medium flows out. Most spring-loaded valves are available for pressure ranges between 1 bar and 1400 bar.

b. Valves with Balanced Bellows
This type of safety valve comes with metallic bellows that increase the poppet valve's surface area. The benefit to this is reduced backpressure hence more safe operation. The spring mechanism is also isolated from the fluid media; thus, there's no undesirable influence on the spring force. That said, most valves with balanced bellows are designed to handle backpressure not exceeding 16 bar.
c. Pilot-operated Safety Valves
A pilot-operated safety valve has its popper valve held onto the nozzle by the inlet pressure, helping avoid leaks or undesired openings. When the inlet pressure is lower than the maximum working pressure, the safety valve will always remain open.
However, as soon as the inlet pressure goes beyond the response pressure, the valves open instantly, allowing the media to flow and reducing the pressure. As soon as the pressure comes back to normal, the valve closes.
All three types of safety valves find applications in different industrial settings. Some of the common areas where safety valves are used include oil and gas, manufacturing, food processing plants, refineries, pressure booster systems, and more.
Choosing a Safety Valve
Before picking a safety valve in the flooded market, you should always consider the following:
The response pressure or the maximum allowable working pressure.
The backpressure at which the valve can operate without causing safety issues.
The discharge capacity of the safety valve.
The valve's operating temperature.
Valve and sealing material.
Besides the above factors, you should also check the certifications required for your specific industry. For instance, safety valves used in the oil and gas industry will vary significantly from those used in the beverage and food industry. Some of the common certifications and standards in the market include ASME, TUV, and ISO 4126.
Summary
A safety valve is an important mechanical device that helps solve the problems associated with overpressure. There are three main types of safety valves: spring-loaded valves, pilot-operated valves, and those with balanced bellows.
When the inlet pressure is higher than the maximum allowable working pressure, safety valves open up to avoid pressure build-up. This, in turn, avoids damages, fires, explosions, and injuries.
The right choice of safety valve will largely depend on your unique needs. Some of the critical factors to consider are response pressure, operating temperature, seal and valve material, discharge capacity, and backpressure. You may also want to do thorough research before choosing a safety valve from a given manufacturer.
For instance, check the manufacturer's reputation, warranty, industry experience, customer reviews, etc.
