Description
Viatran’s Model 245 DigiComp pressure sensor is among our most accurate pressure transmitters for industrial test and research applications. The 245 measures gage and absolute pressure from 3 PSI to 5,000 PSI (0.2 to 345 bar) with
standard accuracy of ≤±0.06% FSO.
Model 245 has external adjustments which allow the user to fine tune the zero reading by use of a potentiometer. It also has adjustment for span and an installed calibration circuit allowing for field calibration. 245 can be customized for outputs anywhere between -10 to +10Vdc, with limitless electrical and process connection options.
