The Series AT23000MR and AT23000MRS ATEX is approved by Photohelic® and uses solid state technology to present the services of Switch/Gages. These switches present the integrated functions of differential pressure switches over a clearly displayed analog pressure gage.
There is no affection to Gage reading for the occurrence of switch operation that tend to give an accurate information for interruption in the power supply.
Concerning the AT23000MR series there is employment of diverse electro-mechanical relays having low ampere ratings for dry circuits. Those applications that need high cycle rates opt for AT23000MRS models along with solid state relays.
The indicators are easy to adjust and can be controlled by knobs on the gage face. There is provision for low as well as high limit control in all the available models. These can be deployed in systems having pressures of 25 psig and extend compatibility with air and several other non-combustible and non-corrosive gases.
