Reliable, Cost-Effective Liquid Level Sensors for Monitoring in Automotive, Control, Household, Industrial and RV Applications

 

CHICKASHA, Okla., USA  - Hermetic Switch, Inc., unveiled its new series of liquid level sensors, also known as float sensors or fluid level sensors.

 

The new PRX+1660 series represents a new product line for the company, which enables Hermetic to address the need for reliable, robust, and reasonably priced sensors for liquid level monitoring applications in appliance, automotive, control, household, industrial, municipal, petrochemical, power generation, processing, and recreational markets.

 

These sensors can be used for level sensing or monitoring of brake fluid, contained water, dilute acid, gasoline, oil, or any number of process liquids, limited only by the series’ material of construction (polyamide or polypropylene).

 

As with all Hermetic Switch reed-switch-based designs, these sensors require no electric power to function since they operate using a permanent magnet¾in this case, designed into the level sensor¾so the sensors are not dependent on batteries and thereby can be used in extreme and/or remote environments for an extended period of time. Both “normally open” and “normally closed” designs are available in the new PRX+1660 series.

 

These PRX+1660 sensors can be mounted at the top or bottom of a liquid container or tank, depending on the application’s requirements. When operated within rated electrical loads, these float sensors will provide millions of cycles, long life, and years of reliable operation.

 

The rated power of the PRX+1660 series is 10 watts and the initial resistance is 0.30 ohms. Other characteristics include:

  • Voltage Rating (V DC Max) – from 180 to 200

  • Current Rating (A DC Max) – from 0.7 to 1.0

  • Voltage Holdoff (V DC Min) – 200 to 240

  • Operating Distance (inch) – 0.177 to 0.728 (4.5 to 18.5 mm)

Pricing for PRX+1660 series products ranges from $4 to $5 USD per unit, depending on the specific model and quantity. Hermetic Switch possesses the ability and desire to custom build solutions for specific applications.
