S120 Submersible in-cylinder position sensor

Description

The Positek S120 in-cylinder position sensor is a submersible version of the P100 in-cylinder linear sensor with a larger electronics housing and wet mate high pressure connector. The S120 in-cylinder position sensor is sealed for a maximum of 350bar combined hydraulic and water pressure. The unit is compact, space-efficient and responsive along almost its entire length.

Like all Positek® sensors, the S120 submersible cylinder sensor provides a linear output proportional to displacement. Each sensor is supplied with the output calibrated to the travel required by the customer, our standard range covers any measurement range from 0-5mm to 0-800mm. If your application requires 10″ (254mm) measurement, then Positek will manufacture the sensor specifically for this angular range. The sensor will measure 10º; however, will still rotate through 254mm. As with all of our packaged sensors full EMC protection is built in.

The sensor is very robust, the body and target tube are made of 316 stainless steel for long service life and environmental resistance.

Overall performance, repeatability and stability are outstanding over a wide temperature range. The Positek sensor is easy to install with M18 or 3/4″ UNF mounting thread options. The target tube can be supplied plain or with a variety of flanges. The S120 also offers a wide range of electrical options.

This sensor is waterproof for submersion up to 3500 meters (350bar) combined water and hydraulic pressure.

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.
