The Functions Of Different Types Of Detector And Sensor

By Karen Sullivan


Science had contributed plenty of inventions that can help the humans in working on their lifestyle. Most of those tools had been utilized in various purposes. Some are made to make a work productive and fast. And some are invented for security and protection. Example of that is Evaporative Light Scattering Detector which is used to examine a solvent or compound after elution from high-performance liquid chromatography.

Nowadays, buildings had increased its security so that hazards will be avoided and prevented. Technologies were made not only to make life more convenient but also to provide protection for the human beings. When you stroll around the mall, you could see CCTVs placed somewhere. Its purpose is to monitor the state of the exterior and interior parts of a property.

But to keep the human beings away from dangers are not just limited by the use of those cameras. Weapons like guns and knives cannot also be seen by a mere camera. And CCTVs cannot warn people about the rising of temperature and smokes in an area. Because of that, detectors and also sensors existed to aid the situation.

Smoke Detectors. It has two components which is the alarm and sensor and two types which is ionization and photoelectric. Ionization alarms are commonly used since the alarm is more responsive at sensing flames. Photoelectric on the other hand, are more receptive on smouldering fires compared to its counterpart. It quickly senses smokes from furniture in living room or bedroom while the ionization provides quick warning in a utility area.

Heat Detector. Basically this device detects the heat presence and the increase of air temperature of a certain area. This does not detect smokes but unlike the smoke detectors, its false alarms are much fewer and when you paired this with that device, a higher chance of fleeing from fire on your house will happen. This is usually installed at garages, warehouses, kitchen facilities and other places.

Motion Sensors. If you want to catch burglars who are intruding your home, this device is the ideal one to catch them. Basically it senses the movement of a certain object or even a person. It also contains many types but the most common type is passive infrared detectors which functions to catch the moving presence at your property.

Metal Detectors. This instrument is part of a detector radar family and is utilized for discrimination and detection of metals. It detects nickel, iron, brass, copper, aluminium, gold, silver, bronze, tin and lead. Its function is really useful especially in military fields, airports and other places. One of its common purposes is to identify concealed weapons.

When you bought these devices at your house for security purposes, of course you need to find some location on where to place it. Asking some professionals is also advisable so you can know the best place to install it. Just make sure to survey your area and find the vulnerable spots at your home. Windows and doors that are located at the back your house or some dark corners are also a good spot.

Knowing the uses or functions of these instruments, maybe you could try on buying and installing it in your home. You can never predict when a dangerous situation will surprise you. With the help of those instruments, your property will be properly protected.
