Series 629HLP Differential Pressure Transmitter, High Accuracy, IP65 Enclosure

 

The DWYER Series 629HLP Differential Pressure Transmitter are suitable for measuring over-pressure, under-pressure, and differential pressure in compatible gases and liquids with 1% accuracy. DWYER Series 629HLP Differential Pressure Transmitter 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.
