Product Selection


Viatran’s Model 574 differential pressure transmitter employs variable capacitance sensing technology for extreme reliability and high accuracy. The 574 measures pressures from 5” WC to 100 PSI with over pressure protection to 3000 PSI. The all welded 316 stainless steel construction allows the airtight and watertight 574 to be in corrosive environments, including salt air or caustic solutions.

External zero, span and calibration controls are hermetically sealed, yet are easily adjusted with Viatran’s magnetically coupled drive system. The signal conditioner in the 574 allows for 5:1 ranging of the transmitter’s
standard pressure range.
