Liquid Level Switches

Pneumatic or electric switches are designed to attach directly to tanks or vessels.  These switches have mechanical “paddles” which float upwards as liquid levels rise.  Once the paddle rises to a precise point, the switch is activated, sending a pneumatic or electric signal to the control system or directly to a valve.

CIRCOR Energy’s liquid level switches are a mechanical float actuated design, either pneumatic or electric used for a high or low level alarm.

Both configurations are available in either carbon steel or stainless steel, and have a maximum temperature rating of 400oF and a maximum working pressure of 2000 PSIG.  The pneumatic level switches also comes with a 3-way block and bleed relay option making it a reliable and cost effective snap acting level controller as well.
