The regulation of pumps or other devices in dependence of the monitored liquid level is one of the most wide-spread methods of control.
The TENSOTERMA Company has developed the contact limit level switch HS-12 - a device with the very large versatility and robustness which is proper for the processes with very hard conditions. The instrument is based on the high frequency principle - damping of high frequency circuit in presence of the liquid. The change is electronically evaluated in the switch itself The switch output transistor with an open collector enables switching the appropriate relay which is a part of control.
The contact switch has following features
|Supply voltage||12 - 24V DC|
|Output||open collector - direct and inverted 0,2A; 24V|
|Dimensions||czlinder with 50mm diameter and 50mm height|
|Mounting||suspension wiht the wieght, mechanical fixation|
