The 10bar submersible S114  is an affordable, durable, water resistant, high-accuracy position sensor. Derived from the P101, the S114 was designed for underwater marine and off-shore applications where the equipment is submerged, shares many of the desirable features such as compact size.

The S114, like all Positek sensors, provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 0-5mm to 0-800mm and with full EMC protection built in. The sensor is very robust, the body and push rod being made of stainless steel for long service life and environmental resistance.

Derived from the popular P101, the S114 has been designed for applications where the sensor may be completely submerged in water up to a pressure of 10Bar, but good sensor performance and cost are still important.

This sensor is waterproof to 100m submersion.

Positek offers a range of options for its standard sensors. Each sensor is manufactured to suit each customer's preferences. If your requirement is outside the options given below, Positek can modify/ redesign a sensor to suit your specific requirement. Standard options are available as below:


Measurement Range

Factory set to any length from 0-5mm to 0-800mm in increments of 1mm. For example, if your application requires 10" (254mm) measurement, then Positek will manufacture the sensor specifically for this angular range. The sensor will measure 10° however will still rotate through 254mm.
