Dwyer 636D-6 is a fixed range differential pressure transmitter with an accuracy of ±0.5% F.S. It operates within a temperature range of -40 to 140°F and has an enclosure rating of NEMA 4. The transmitter has a response time of 20 ms and can be powered by a 12-30 VDC or 8-14 VDC source. It has a 4-20 mA or 1-5 VDC output signal and features fixed zero and span adjustments. The wetted material is types 316L SS and it has a pressure limit of 3x full scale differential pressure. The transmitter is suitable for use with compatible gases, liquids, or vapors and can be mounted in various orientations with a ±0.05 psi/90° rotation from horizontal. It is designed for use in hazardous locations and has a thermal effect of ±2% F.S./50°F. The loop resistance is 900 ohms max. and it has a stability of ±1.0% F.S./yr. The current consumption is 4-20 mA for current output models and 3 mA for voltage output models.
