Digital indicators AN41 AN44
The AN41 and AN44 indicators provide excitation voltage ( 28V with 75 W shunt resistance) for 4-20 mA or 0-20 mA pressure and temperature transmitters. Various engineering units are available. Overall systems (Bourdon-Haenni transmitters + indicator) can be adjusted or calibrated in factory. All programming operations (0, full scale for AN41, AN44 and set points, AN41 only) are imple­mented on the front panel.
