Dwyer, 629C-03-CH-P1-E3-S3-AT, 629C Pressure Transmitter 0-25 psid with Alu. Tag Wet/Wet Differential Pressure Transmitter (Process Connection - 1/4" Male NPT; Electrical Connection - Cable gland with 9' of prewired cable; Output Signal - 3-wire: Field selectable 0 to 5, 1 to 5, 0 to 10, or 2 to 10 VDC). Features: Versatile, high accuracy device for liquid or gas supports designs requiring more precise measurements in support of application. Minimum components provide excellent response and reliability. Zero control reduces installation and service time. Terminal block reduces wiring difficulties saving installation time. The aluminum tags may contain 2 lines (approximately 9 char. per line). The characters may be hand-written. Useful for identifying where the product goes in a large facility. Applications: Flow elements. Heat exchangers. Filters. Coils. Chiller. Pumps. The Series 629C Wet/Wet 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 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. The Series 629C Differential Pressure Transmitter is designed to meet NEMA 4X (IP66) construction.
