The intrinsically safe M100 is ATEX and IECEx approved for use in potentially explosive gas/vapour, dust atmospheres and mining environments.
It is designed for demanding hydraulic or pneumatic cylinder position feedback applications where service life, environmental resistance and cost are important and is ideal for OEMs seeking good sensor performance for arduous applications in hazardous areas.
Overall performance, repeatability and stability are outstanding over a wide temperature range. The unit is highly compact and space-efficient, being responsive along almost its entire length.
Like all Positek sensors, the M100 provides a linear output proportional to displacement. Each unit 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 rugged, being made of stainless steel with an inert fluoropolymer-sheathed probe and stainless steel target tube. The sensor is easy to install in cylinders and has 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 amplifiers 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 amplifier and the sensor.
This sensor is ATEX/IECEx approved to:
Ambient temperature range extended to -40°C to +80°C .
|Galvanic Isolation Amplifier
Intrinsically safe sensors must be used with a galvanically isolated amplifier with safety parameters not exceeding:- Ui: 11.4V, Ii: 0.2A, Pi: 0.51W. Sensor can be installed with a cable length up to 1000m maximum from the amplifier, cable capacitance and inductance can be up to:- Capacitance: 200 nF max, Inductance: 810 μH max.
Approved amplifiers are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.

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:
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.
