Part of the Additel ADT761A series, the ADT 761A-500 generates and controls from vacuum pressures up to 500 psig (35 bar.g). With the built-in barometer both gauge and absolute pressures can be realized. The ADT 761A-500 comes with a CP500 module (-12.5 to 500 psig) for the high range and the low range can be preconfigured based on the variety of modules available down to 10 psig (0.7 bar.g).
The ADT161 pressure module is sold separately, Click the Accessories Tab to see the pressure modules
