IS sensors.

Monitran has launched two series of intrinsically safe sensors. Certified to ATEX and IECEx Group II, the MTN/2285IT and MTN/2200IT series are sealed to IP67, are available with integral cables or 4-pin connectors and are ideal for measuring vibration levels and temperatures in areas where explosive gases, liquids or dust may be present.

Intended for monitoring applications, the MTN/2285IT series comprises sensors with DC current outputs, in the range 4-20mA, proportional to RMS velocity (mm/s) and temperature as a voltage at a sensitivity of 10mV/oC. In addition, the operating temperature is certified to T6 (-55oC ≤ Ta ≤ +45oC).

The MTN/2200IT series is aimed more at analysis applications and features constant current accelerometers with isolated outputs for acceleration, in volts at a standard sensitivity of 100mV/g, and temperature at a sensitivity of 10mV/oC. The operating temperature for this series is certified to T4 (-55oC ≤ Ta ≤ +95oC).

Andy Anthony, Managing Director of Monitran, comments: “The monitoring of both vibration and temperature levels is at the heart of many predictive maintenance strategies. Adding a temperature measuring capability to our existing range of ATEX-certified sensors is a goal we’ve had for some time as, for instance, we understand most engineers view temperature as the foundation for bearing monitoring. Having put our robust dual-output sensors through the rigorous ATEX and IECEx certification processes, we’re able to provide our customers with a variety of products to meet their monitoring requirements in hazardous areas.”
