629C-05-CH-P2-E5-S3 is a series 629C wet/wet differential pressure transmitter. It 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 4-20mA output signal or field selectable voltage. Small internal volume and minimal moving parts result in exceptional response and reliability. The terminal block, as well as a zero adjustment button, are easily accessed under the top cover. Typical applications include flow elements, heat exchangers, filters, coils, chiller and pumps.
