The intrinsically safe M117 is ATEX and IECEx approved for use in potentially explosive gas/vapour and dust atmospheres and mining environments.
It is designed for industrial and scientific feedback applications 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 very compact and space-efficient with a small 19mm diameter body. The sensor is very robust, the body and push rod being made of stainless steel. The sensor is easy to install with mounting options including M5 male stud and M5 rod eye bearing. The push rod can be supplied free or captive, with male M5 thread or M5 rod eye.
Like all Positek sensors, the M117 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 0-350mm and with full EMC protection built in. The M117 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.
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 0-350mm in increments of 1mm. For example, if your application requires 10" (254mm) measurement, then Positek will manufacture the sensor specifically for this length. The mechanical length and calibration will be set up for 254mm.
