Using solid state technology, the Series AT-3000MR/MRS ATEX/IECEx Approved Photohelic® Switch/Gauge combines the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gauge. Gauge reading is unaffected by switch operation and will indicate accurately even if power is interrupted. AT102-3000MR series employ versatile electromechanical relays with low amperage ratings-ideal for dry circuits. For applications requiring high cycle rates, choose AT102-3000MRS models with SPST (NO) solid state relays. Easy to adjust set point indicators are controlled by knobs located on the gauge face (accessible opening case after de-energizing instrument). All models provide both low and high limit control. Compatible with air and other non-combustible, non-corrosive gases. Flameproof enclosures are available with glass window which allows for viewing of set point needles and process pressure. Compatible with air and other non-combustible, noncorrosive gases.
Important notes for installation:
Attention: Check local safety rules and warnings on unit and manual for a correct use of the instrument in hazardous areas.
