Gas and Vapour Application Sensors


As the UK’s leading industrial position sensor manufacturer, Positek supplies a number of rotary sensors, specifically designed to ensure intrinsic safety in environments that are subject to the production of hazardous gas. 

Intrinsically safe systems restrict the flow of electrical energy into a hazardous or potentially explosive environment. Any sparks that may occur as the result of an electrical failure are therefore not strong enough to cause ignition, even when hazardous is present. 

When dealing in harsh or hazardous environments (for example one that might contain or produce hazardous gases or vapours or explosive dust), it is important to ensure all machinery used is of the correct hazardous area classification. All of our intrinsically safe rotary sensors have attained one or more of the following certifications, and are therefore suitable for applications that might produce or be exposed to hazardous gases:

    •   ATEX approval
    •   IECEx approval
    •   CSA approval
    •   ANZEx approval

Not only has our entire product range gained industry approval; every rotary position sensor that we manufacture employs our simple, inductive technology, and therefore delivers the durability and reliability that cannot be matched by an rvdt sensor or rotary potentiometer.

Positek’s rotary sensors are also extremely robust, offering outstanding performance in all hazardous gas applications over a wide temperature range. Because of this we are proud to say that our IECEx, ANZEx, CSA and ATEX equipment has an extremely low failure rate.
