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 standard 4 to 20 mA 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. The Series 629C Differential Pressure Transmitter is designed to meet NEMA 4X (IP66) construction. Wetted Materials: Without valve: 316, 316L SS. Additional wetted parts with valve option: Buna-N, silicone grease, PTFE, brass 360, copper, and reinforced copolymer. Stability: ±1% FS/year. Thermal Effect: Avg 0.04%/°F (0.072%/°C) (includes zero and span). Output Signal: 2-wire: 4 to 20 mA; 3-wire: Field selectable 0 to 5, 1 to 5, 0 to 10, or 2 to 10 VDC. Zero and Units: Push buttons inside conduit enclosure. Response Time: 400 msec. Loop Resistance: Current output: 0 to 1250 ? (max), Rmax = 50(Vps-10); Voltage output: Minimum load resistance = 5 k?. Current Consumption: 28 mA (max). Display: Optional 4-1/2 digit LCD field attachable display. Enclosure Rating: Designed to meet NEMA 4X (IP66). Mounting Orientation: Not position sensitive. CE Approved.
