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 levels and detect temperatures in critical processes. Evaluation units and probes that can be connected to them and that monitor the processes in the application may complement each other.
Where are such sensors used?
According to their important function process sensors are used in many industries such as:
- Food processing
- Chemical industry
- Wastewater technology
In sewage technology process sensors monitor, for example, 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, for example, water in oil.
Process sensors at Automation24
Automation24 has various sensors in stock that can be integrated in technically complex applications. An example is the magnetic-inductive flow meter SM7000 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 TM4101 screw-in sensor is another component of process sensors that can be recommended. It detects temperatures in the range from minus 40 to plus 150 degrees Celsius with precision. This in ensured thanks to the exact resistance thermometer. Although the robust probe is 6mm thick and resists to enormous pressures up to 400 bar, it features ideal response times of T05 = 1 s and T09 = 3 s.
At Automation24 you find a large selection of process sensors at very favourable prices. Select the sensor suitable for your application now!
