Description
Specialized compact SDV “Low Power” intelligent pressure transmitters have a unique feature — they are adapted for use in systems with autonomous power supply. These transmitters are used for collecting and transmitting telemetry data, including in heat energy, gas, and oil metering units where connection to mains power sources or wired data transmission is difficult.
SDV intelligent transmitters are supplied with valve blocks.
Applications
-
Oil and gas industry
-
