The Model 245 DigiComp pressure sensor from Viatran is one of the company’s most precise pressure transmitters developed for industrial test and research applications.
The 245 DigiComp pressure sensor quantifies gage and absolute pressure from 3 to 5,000 PSI, or 0.2 to 345 bar, with a standard precision of ≤±0.06% FSO.
Features
 |
All stainless-steel construction |
 |
High precision |
 |
Suitable for low pressure applications |
 |
Shunt calibration circuit option |
 |
Several options are available |
External adjustments in the Model 245 DigiComp pressure sensor enable users to further tune the zero reading with the help of a potentiometer. The pressure sensor also includes adjustments for span, and an embedded calibration circuit enables calibration on the field.
The Model 245 DigiComp pressure sensor can be custom-made for outputs anywhere from −10 to +10 VDC, with unlimited electrical and process connection options.
