Dwyer 616D-7 is a differential pressure transmitter with a temperature range of 14 to 185°F (-10 to 85°C). It has an accuracy of ±0.25 FS @ 77°F (25°C) and requires a power supply of 10 to 35 VDC (2-wire), 17 to 36 VDC, or isolated 21.6 to 33 VAC (3-wire). It features a screw-type terminal block for electrical connections and offers a 4-20 mA (2-wire) or 0-10 VDC (3-wire) output signal. With push-button zero and span adjustments, this transmitter is suitable for air and non-combustible, compatible gases. It can be mounted vertically on a 1.378" (35 mm) DIN rail. Wetted materials and pressure limits can be obtained from the manufacturer. The package includes 2 barbed fittings for 1/8" (3.12 mm) and 3/16" (4.77 mm) ID rubber or vinyl tubing. Other specifications include ±0.02% FS/°F (0.036% FS/°C) thermal effect, loop resistance of up to 1250 Ω max for current output and load resistance of at least 1 kΩ for voltage output, ±1% FS/yr stability, and a maximum current consumption of 40 mA.
