Dwyer 636D-3 Fixed Range Differential Pressure Transmitter

Dwyer 636D-3 is a fixed range differential pressure transmitter with an accuracy of ±0.5% F.S. It operates in temperatures ranging from -40 to 140°F and has an enclosure rating of NEMA 4. It can handle a pressure limit of 3x full scale differential pressure and has a response time of 20ms. The transmitter has a 4-20 mA or 1-5 VDC output signal and can be used with compatible gases, liquids, or vapors. It requires a power supply of 12-30 VDC for 4-20 mA outputs and 8-14 VDC for 1-5 VDC outputs. The transmitter has zero and span adjustments that are fixed and uses Types 316L SS as the wetted material. It has a maximum loop resistance of 900 ohms for current outputs and a minimum lead resistance of 50k ohms for voltage outputs. The transmitter has a stability of ±1.0% F.S./yr and a thermal effect of ±2% F.S./50°F. It consumes 4-20 mA for current output models and 3 mA for voltage output models. The mounting orientation can be rotated within ±0.05 psi/90° from horizontal. It is suitable for use in hazardous locations and comes with a 2 ft, 22 AWG cable and a 3/4" female NPT conduit for electrical connections.
