Model 570 Pressure Transmitter
All welded construction and stainless steel surfaces makes the 570 ideal for corrosive environments. The transmitters O-ring free design ensures reliability with corrosive media. Viatran’s 570 FM approved labelled units are designed to meet NEC/API Dual Seal requirements. For the most corrosive environments, Hastelloy, Inconel, and 316 SS wetted parts are available.
