The operating principle of process sensors
Process sensors perform various tasks of detecting and monitoring process values in industrial applications. In pneumatic applications they verify, for example, the occurring pressure, inform about the current material levels, and detect temperatures in critical processes. Evaluation units and probes function as complimentary accessories that can connect to these sensors and monitor their processes in the application.
Where are such sensors used?
As a result of their crucial function, process sensors see use in many industries, such as:
- Food processing
- Chemical industry
- Wastewater technology
As an example, in sewage technology, process sensors monitor levels in tanks or the pressure in hydraulic systems and transmit the current measured values to the controller. In addition, there are special sensors that detect if an undesired liquid has penetrated, such as water in oil.
Process sensors at Automation24
Automation24 has diverse sensors in stock, ready for integration into technically complex applications, among them the magnetic-inductive flow meter SM8000 from ifm. It monitors the flow of conductive liquids such as coolants that are needed for welding systems. The sensor is designed for flow quantities of up to 100 litres per minute. The current measured values are indicated on a 4-digit alphanumeric LED display. The TT1281 screw-in resistance thermometer detects temperatures in the range from minus 40 to plus 150 degrees Celsius, with precision ensured by the exact resistance thermometer. Despite the robust probe’s 6mm thickness and resistance to pressures up to 160 bar, it features ideal response times of T05 = 1 s and T09 = 3 s.
At Automation24, we carry a large selection of process sensors at very favorable prices. Select the sensor suitable for your application today!
