Description

Viatran’s Model 345 DigiComp pressure sensor is among our most accurate pressure transmitters for industrial test and research applications. The 345 measures gage and absolute pressure from 3 PSI to 5,000 PSI (0.2 to 345 bar) with
standard accuracy of ≤±0.06% FSO.

The Model 345 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.  In addition to a high accuracy option between temperature range of -40°F to 185°F, 345 has a limitless array of electrical and process connection options to meet any pressure measurement requirement.
