Intrinsically Safe G117 is CSA approved for use in potentially explosive gas/vapour atmospheres. The G117 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 G117 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 G117 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 sensor can be installed with a cable length up to 1km between the sensor and the amplifier.
|CSA Approval||This sensor is CSA approved to:|
Class I, Zone 0
Ex ia IIC T4 (Ta = -40°C to +80°C)
AEx ia IIC T4 (Ta = -40°C to +80°C)
Designates the sensor as belonging to; Class I, Zone 0: suitable for all areas except mining, : can be used in areas with continuous, long or frequent periods of exposure to hazardous gas / vapours. Protection class ia IIC, denotes intrinsically safe for Zones 0, 1 & 2 and IIA, IIB and IIC explosive gases. Temperature class T4: maximum sensor surface temperature under fault conditions 135°C. Ambient temperature range extended to -40°C to +80°C. Approval only applies to the specified ambient temperature range and atmospheric conditions in the range 0.80 to 1.10 Bar, oxygen <=21%.
|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.

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" (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.
