Series 621 explosion-proof pressure transmitters combine diffused semiconductor and sputtered thin film sensor technology with robust electronics to perform in hazardous locations.
Series 621 explosion-proof pressure transmitters combine diffused semiconductor and sputtered thin film sensor technology with robust electronics to perform in hazardous locations. Constructed with corrosion-resistant stainless steel and Elgiloy wetted parts, they offer accuracy of ±0.25% Full Scale (B.F.S.L.) for pressure ranges from vacuum to 15,000 psi. Output signals are 4 to 20 mA, 2-wire; 1 to 5 Vdc, 3-wire; 0.5 to 4.5 Vdc, 3-wire.
