H125 Submersible Rugged Stand Alone Linear Position Sensor

Intrinsically safe 350bar is CSA approved for use in potentially explosive dust atmospheres, sealed for continual submersion up to 3500m (350bar 5000psi). The H125 is a heavy-duty, high pressure sealed version of the H115 sensor with a stronger 12.6mm push rod, recommended for applications where vibration is an issue or there is a need for longer travel sensors which are to be mounted horizontally between rod eyes. It remains an affordable, durable, high-accuracy position sensor designed for applications where the sensor requires IP68 Sealing. The unit is highly compact and space-efficient, being responsive along almost its entire length. Like all Positek® sensors, the H125 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 M8 thread, or an M8 stainless steel rod eye. The H125 also offers a selection of mechanical and electrical options, environmental sealing is to IP68 350 Bar (5000psi, 3500m).

Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier .  Approved galvanic isolation amplifiers (G005) are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.

The sensor can be installed with a cable length up to 1km between the sensor and the amplifier.
