The intrinsically safe M138 is ATEX and IECEx approved for use in potentially explosive gas/vapour and dust atmospheres and mining environments. The M138 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 19 mm 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 springloaded with a ball end. The M138 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 (X005) 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. Drawing, Datasheet, Installation Guide & P/N Configurator
