Dwyer 616WL-14 is a differential pressure transmitter with an accuracy of ±0.25 % FS @ 77°F (25°C). It operates on a power requirement of 10 to 36 VDC (2-wire), 17 to 36 VDC, or isolated 21.6 to 33 VAC (3-wire). It has a response time of instantaneous or selectable 3 s, and an enclosure rating of NEMA 4X (IP66). Its output signal options include 4 to 20 mA (2-wire), 0 to 5 VDC, or 0 to 10 VDC (3-wire). It is suitable for air and non-combustible, compatible gases. The transmitter allows for zero and span adjustments through digital push-buttons. It can be mounted in any orientation and has a thermal effect of ±0.02% FS/°F (±0.036% FS/°C). The loop resistance is 0-1250 Ω max for current output and 1 kΩ minimum load resistance for voltage output. Its stability is ±1% FS/yr and it has a maximum continuous current consumption of 21 mA.
