Level sensors for every need

We manufacture liquid level switches with an endless combination of sizes, mounting options and materials to suit your specific level sensing requirements.

Our miniature polypropylene sensors are durable, versatile and economical. For applications that involve high pressure or corrosive conditions, our stainless steel level sensors are sturdy and reliable and come in large, full-size configurations for harsh environments or with compact floats for tight spaces.

Our side-mounting level sensors come in tapered NPT and bulkhead-style fittings for mounting from inside a chamber or outside. These sensors are excellent for low level indication since the float can remain submerged in liquid while the wires are routed safely away through the container wall.

New Extended Threading Sensor

Chicago Sensor`s newest vertical mount float switch offers flexibility in mounting for applications that require a long stem and the ability to adjust mounting height for different product configurations. The switch can also be used when your customers need to adapt your product to their individual fluid level sensing requirements.

This new adjustable level switch offers durable stainless steel construction with a float diameter of just one inch. Each switch comes with two hex nuts and two silicon o-rings. The stem features a 2.4 inch long threaded section which allows users to mount the switch high, low or at different heights from time to time to adjust to varying fluid level sensing objectives. The overall stem length is 4.9 inches. Designed originally as a water level sensor for tank level control, this liquid level control switch can be adapted to a variety of fluids. We can also design other adjustable level switches quickly and economically.

Whether your need is for a liquid level switch to do testing in a prototype or a liquid level detector for an end use application at the best possible pricing, we are here to support you with our broad variety of in-stock liquid level controls, specialized design services and technical advice. Our goal? Supporting Your Innovation™ with reliable, economical solutions.
