Digital Vacuum Indicators are board mounting type which acknowledges the contribution from a strung end vacuum transmitter installed in the field. The vacuum sensor is indicator by way of a 2 core cable connection and the separation between the indicator and the sensor can be upto 1000 meters. Without loss of signal accuracy. The digital vacuum pointers are accessible in 2 models dependent on the estimating range. The digital vacuum indicator Model AI-VAC ABS 1 measures from 760 to 0 Torr Absolute and the Model AI-VAC 1 estimates vacuum from 0 to – 760 mm. Hg. The vacuum transmitters are tempered steel sensors with all hardened steel wetted parts appropriate for forceful media conditions.
