Industrial Sensors And Controls

Industrial Sensors And Controls

Sensors are devices that detect signals. They respond to changes which can be either chemical or physical, such as distance, temperature or speed. They can convert all of those signals into electric signals. They find many uses in every day objects like alarms, car parking sensors, tire pressure monitoring systems in cars, etc. The sensor itself cannot be seen and people are often unaware that it’s there.

Because the demand for work efficiency continues to grow in the mass production industry, a lot of manufacturers seem to need to invest in industrial sensors and controls to ensure the quality of the workflow. Industrial sensors and controls equipment can be used in many industrial processes – from assembling and creating parts, to processing packaging products for delivery. The main job of most sensors is to inform you that something is not right, so working in dangerous industrial zones that have the potential of putting people in danger requires the workplace to have a bunch of sensors to inform the workers of an oncoming disaster. Here are a few sensors frequently found in industrial zones.

Temperature Sensors
These find usage in many areas in the industry. As their name implies, they are used to determine the temperature of a given medium, be it the overall temperature in the work place, the temperature of a machine, etc. Some of these sensors operate in a few different ways. The most common methods these sensors operate with are called expansion differential, resistance differential and infrared detection.

Pressure Sensors
Pressure sensors detect the pressure caused by liquids or gasses by converting their physical force into electric signals. These sensors can also indirectly measure other variables such as water level, altitude and speed. High-end pressure sensors can monitor high-speed changes in the pressure, like fuel pressure in engines. The most common types of pressure sensors are pressure gauges and barometers. In industrial settings, the pressure gauges are the more common option, because they measure pressure in sealed environments.

Optical Sensors
These sensors are used to detect the presence of electromagnetic energies, like electricity, light and other elemental particles. They are frequently used in scientific studies, but have also found their place in mass produced technology, especially in digital cameras. Most optical sensors are used in the study of quantum physics because they are sensitive to even detect a single elemental particle. Other optical sensors are used in digital cameras, because they provide a perfect balance of sensitivity, cost and durability.

Proximity Sensors
These detect movement within the sensor’s field and are used for security, safety or efficiency. They utilize infrared radiation or a radar to spot occupancy or motion. Proximity sensors allow the user to switch lights off when a room is not occupied, as well as turn them on when it’s needed, activate security cameras or stop a dangerous machine when someone or something enters a dangerous zone.
