Description
The Positek slim-line H138 linear position sensor is CSA approved for use in potentially explosive gas/vapour and dust atmospheres. The H138 is designed for a wide range of industrial applications and is ideal for OEMs seeking good sensor performance in situations where a small diameter, short-bodied sensor is required for operation in hazardous areas. The unit is compact and space-efficient, being responsive along almost its entire length, and like all Positek® sensors provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 0-51mm to 0-100mm and with full EMC protection built in.
Overall performance, repeatability and stability are outstanding over a wide temperature range. The sensor has a compact 19mm diameter stainless steel body, is easy to install and set up. The stainless steel mounting flange has two 3.2 mm by 30 degree wide slots on a 25 mm pitch. The stainless steel plunger can be supplied free or captive, with female M4 thread, or spring-loaded with a ball end. The H138 slim-line sensor also offers a range of mechanical options, environmental sealing is to IP67.
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 H138 linear position sensor can be installed with a cable length up to 1km between the sensor and the amplifier.
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.
