Ex certified vibration monitoring

31 July 2008

Hansford Sensors has launched a range of IEC Ex certified, intrinsically safe vibration sensors with 4-20mA outputs, ideal for direct use with PLC, BMS or other 4-20mA input modules. The low cost HS-420I and HS-422I sensors are designed for use in online vibration monitoring applications where the environment contains inflammable gases, fumes, chemicals, powders, dust etc., as found in many industries such as mining, gas production, paints, petrochemical, offshore, pharmaceutical.

Also certified for ATEX, the new models will allow maintenance engineers to monitor vibration levels of pumps, fans, compressors, motors, conveyors, drilling rigs and all types of rotating machinery, which are in a potentially explosive working environment.

The HS-420I series is sealed to a minimum of IP67 and can be used in both Group I (Mining) and Group II (Petrochemical) applications. With their construction in stainless steel and ability to withstand tough operating conditions, the sensors offer reliability, optimum performance and long service.
