Series 629 Wet/Wet Differential Pressure Transmitter

0.5% Accuracy, NEMA 4X Enclosure

The SERIES 629 Differential Pressure Transmitter monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4-20 mA output signal for two wire circuits. Small internal volume and minimum moving parts result in exceptional response and reliability. Terminal block zero and span adjustments are easily accessed under the top cover. The Series 629 Differential Pressure Transmitter is designed to meet NEMA 4X (IP66) construction.

This series is being phased out in 2017, see Series 629C for additional ranges.
