Dwyer 616D-8 is a differential pressure transmitter with a temperature range of 14 to 185°F (-10 to 85°C) and an accuracy of ±0.25 FS @ 77°F (25°C). It operates on a power requirement of 10 to 35 VDC (2-wire) or 17 to 36 VDC, or isolated 21.6 to 33 VAC (3-wire). The output signal can be 4 to 20 mA (2-wire) or 0 to 10 VDC (3-wire). It has push buttons for zero and span adjustments and can be mounted vertically on a 1.378" (35 mm) DIN rail. The wetted material, pressure limit, and thermal effect can be consulted with the factory. The process connection is 1/8" female NPT and accessories include two barbed fittings for different tubing sizes. It has a thermal effect of ±0.02% FS/°F (0.036% FS/°C), stability of ±1% FS/yr, and a current consumption of 40 mA max.
