Fluid Level Gauge, Fluid Level Sensor & Temperature Switch – FSA / FSK / TS

Fluid Level Gauge, Fluid Level Sensor & Temperature Switch

FSA fluid level gauges, FSK fluid level sensors and TS temperature switches are designed to monitor and control the level of operating fluid.

FSA

By using the FSA, the fluid level can be easily seen on the outside of the tank. The fluid enters the unit via the lower connection bore and is clearly visible in the tube. By selecting the right size, the monitoring of the particular fluid level is possible.

FSK

By using the FSK, the fluid level is monitored via an electrical switching signal. This switch signal is also a possible mean for a warning or to control the level. The fluid enters the unit via the lower connection bore and pushes a float up the tube. The float now shows the level of the fluid in the tank. If the level of the fluid drops again, the float will activate a switch contact. For the NO switch (type C) the circuit will then be closed, for the NC switch (type O) the circuit will be opened.

The special dual switching model (type W) offers two possibilities: close on contact or open on contact.

TS

The TS is a very useful additional option to the FSA and FSK products. However, it also has a useful application as a separate accessory for systems.
Once fitted, the temperature sensor of the TS is surrounded by operating fluid. When the nominal temperature is reached, a contact opens and the circuit is broken.

This switching process can be used either as an alarm or to monitor the temperature. When the temperature of the fluid drops by approx. 15 K, the circuit closes again.

Applications:

In order to monitor and control levels of operating fluid, we can use fluid level gauges FSA, fluid level sensors FSK and temperature switches TS.
Areas of application are for example machine tools, system engineering, tanks for hydraulic, lubricating.
