Model 34B—Pressure Transmitter

The Model 34B pressure transmitter from Viatran is one of the company’s most flexible pressure transducers when it comes to industrial applications. The 34B pressure transmitter quantifies pressures ranging from 0–100 PSI to 0–30,000 PSI with an established linearity of ≤ ±0.25% FSO.

The Model 34B pressure transmitter features a Solid Machined Sensor and an output of 4–20 mA.


All stainless steel construction
Several options are provided
Shunt calibration circuit option available
