H115 Submersible Linear Position Sensor

Description

Positek H115 Submersible IP68 Rugged Linear Position Sensor is intrinsically safe. CSA approved for use in potentially explosive dust atmospheres. The H115 Submersible IP68 Rugged Linear Position Sensor is a heavy-duty version of the H114 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 H115 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 submersible linear position 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 H115 also offers a selection of mechanical and electrical options, environmental sealing is to IP68 10 Bar.

All of Positek’s position sensors are manufactured to the highest quality and use our very own patented non-contact technology. This helps to ensure the highest levels of accuracy and reliability, even in the harshest of environments. Every position sensor that Positek manufactures uses their inductive sensor technology to ensure high-precision results, and is fully customisable to meet the unique requirements of your business.

With over 25 years’ experience as a sensor manufacturer and using our onsite production facility, Positek has the flexibility to manufacture and customise any industrial position sensor, including tilt sensors and inclinometers, to any size or specification.

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" (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.

Galvanic Isolation Amplifier

It is imperative Positek® intrinsically safe sensors be used in conjunction with a galvanic barrier to meet the requirements of the product certification. The Positek G005 Galvanic Isolation Amplifier is purpose made for Positek IS sensors making it the perfect choice. Refer to the G005 datasheet for product specification and output configuration options.

The Positek® G005 Galvanic Isolation Amplifier is available with 0.5 - 9.5V or 4 - 20mA transmission output options or reverse outputs of 9.5 - 0.5 volts or 20 - 4 mA.
