Series 629HLP Differential Pressure Transmitter
High Accuracy, IP65 Enclosure
The Series 629HLP Differential Pressure Transmitters are suitable for measuring over-pressure, under-pressure, and differential pressure in compatible gases and liquids with 1% accuracy. The 629HLP is suitable for all measuring tasks in commercial, industrial or sanitary applications. Its single sensor design allows it to measure small increment pressure changes, and converts them to a linear analog output signal from 4 to 20 mA or 0 to 10 VDC.
NIST CALIBRATION available in Product Configurator.
