Dwyer 636D-6-LP Fixed Range Differential Pressure Transmitter

Dwyer 636D-6-LP is a fixed range differential pressure transmitter designed for use with compatible gases, liquids, or vapors. It has an accuracy of ±0.5% F.S. and a response time of 20 ms. The transmitter operates at temperatures ranging from -40 to 212°F and has an enclosure rating of NEMA 4. It features a 4-20 mA DC or 1-5 VDC output signal, with zero and span adjustments fixed. The wetted material is Types 316L SS, and the transmitter has a pressure limit of 3x full scale differential pressure. It is suitable for hazardous locations and has thermal effects of ±2% F.S./50°F and stability of ±1.0% F.S./yr. The transmitter requires a power supply of 12-30 VDC for 4-20 mA outputs and 8-14 VDC for 1-5 VDC outputs, with reverse polarity protection. It has electrical connections of 2 ft, 22 AWG cable and 3/4" female NPT conduit. Mounting orientations can vary within ±0.05 psi/90° rotation from horizontal. Loop resistance is 900 ohms max. for current outputs and minimum lead resistance of 50k ohms for voltage outputs. Current consumption is 4-20 mA for current output models and 3 mA for voltage output models.
