ToughSonic® TSL Family
Push-button "Teachable"
Ultrasonic Level Sensor / Control


TSL-30S, TSL-15S, TSL-21S Series

Liquid tight, with CONTROL and ALARM outputs

These small sensors are designed for simple level control applications. They measure distance to the liquid surface from above, so nothing touches the liquid. Liquid level is control pumps or valves to maintain the level between low and high level setpoints. Control is maintained by either filling or emptying the vessel. An alarm output indicates abnormal conditions. Control and alarm setpoint distances are calibrated using the push-button "Teach" feature.

Level can also be controlled with our new TSPC Family of computer configurable models
