Certified Dwyer 677B-04 Differential Pressure Transmitter

Dwyer 677B-04 is a reliable and accurate differential pressure transmitter. It has an operating temperature range of 0 to 185°F and can be stored in temperatures ranging from -65 to 220°F. With an accuracy of ±0.4% FS, this transmitter provides precise measurements. It requires a power supply of 16 to 32 VDC and has a response time of approximately 10 ms. With an enclosure rating of NEMA 4, it is suitable for various environments. The output is a 4 to 20 mA DC signal, making it compatible with most systems. This transmitter is designed for use with air and non-corrosive gases. Its wetted materials include 302 SS, glass, nickel, silicone rubber, and brass. It has a pressure limit of 15 psi and features a 3/16″ OD barbed brass pressure fitting for the process connection. The thermal effect, which includes zero and span, is less than 0.028% FS/°F within the temperature range of 0 to 185°F. The loop resistance ranges from 0 to 800 Ohms in DC. With a stability of ±1% FS/yr, the Dwyer 677B-04 is a reliable solution for differential pressure measurement.
