S115 Submersible Linear Sensor

S115 Submersible Linear Position Sensor

The 10bar submersible S115 is a heavy-duty version of the submersible S114 submersible linear sensor with a stronger push rod and fixings, recommended for applications where vibration is an issue or there is a need for longer travel sensors to be mounted horizontally between rod eyes. It remains an affordable, durable, high-accuracy position sensor designed for applications where the sensor would be completely submerged during normal operation, up to a pressure of 10Bar. The unit is highly compact and space-efficient, being responsive along almost its entire length. Like all Positek® sensors, the S115 provides a linear output proportional to displacement. Each sensor 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.

Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor is easy to install with mounting options including stainless steel M8 rod eye bearings and body clamps. The push rod can be supplied free or captive, with female M8 thread, or an M8 stainless steel rod eye. The S115 also offers a wide range of mechanical and electrical options, environmental sealing is to IP68 10Bar.

This sensor is waterproof for submersion to 100 meters.

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.
