Level Sensors - Series EP1226

Series EP1226 Level Sensor

The EP1226 solid state, non-contact level sensor monitors liquid level in a variety of applications. Encapsulated in a low profile enclosure, the electronic mass sensor is configured to work either in conjunction with the Tecmark® EP1217 / EP1227 timers or as a stand-alone device. Designed for use with non-metallic containers. The sensor mounts via double sided adhesive backed foam tape to the "dry" side of the container.

Use with EP1217 / EP1227 timers

The level sensor interfaces with the motor timer, via an optional three-pin header located on the timer to facilitate easy electrical connection. The level sensor will inhibit actuation of the timer's load relay until a pre-selected fluid level has been attained. If fluid level drops below the sensor actuation point during normal operation of the timer, the load relay will immediately de-energize to prohibit potential equipment or liquid spray damage. The timer will remain de-energized until the proper fluid level is restored and the PCB mounted air switch is actuated again.

Stand Alone System

Powering a relay coil the sensor provides a logic signal to energize the relay when sufficient liquid level is sensed, or de-energize the relay if liquid level is insufficient.

Typical Applications
