Description
The compact SDV intelligent differential pressure transmitter converts pressure into a unified output signal of 4–20 mA, 0.4–5.5 V, RS485, or CAN. It enables the creation of modern monitoring, automatic regulation, and commercial metering systems.
SDV transmitters are manufactured in general industrial and explosion-proof versions (SDV Ex, –Exd, –Exdia) and are supplied with valve blocks.
Applications
-
Oil and gas industry
