S115 Rugged Waterproof Submersible Stand Alone Linear Position Sensor.


Position feedback for marine and offshore applications
Available in any travel from 5mm to 800mm.


The S115 LIPS® (Linear Inductive Position Sensor) is a heavy-duty version of the water resistant S114 sensor with a stronger 12.7mm push rod, recommended for applications where vibration is an issue or there is a need for longer travel sensors are 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 5mm to 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.

Preferences

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 5mm to 800mm in increments of 1mm.
For example, if your application requires 10" (254 mm) measurement
then Positek will manufacture the sensor specifically for this length.
The mechanical length and calibration will be set up for 254 mm.
