Dwyer 610-25C-BDV is a low differential pressure transmitter with a temperature range of -20 to 160°F (-29 to 71°C). It has an accuracy of ±0.25% or ±0.5% F.S. and operates on a power requirement of 13.5 to 30 VDC. The response time is 0.02 to 0.04 seconds and it has a fire retardant ABS enclosure rating. It has a 4 to 20 mA output and is suitable for air or similar non-conducting gases. The transmitter is vertically mounted with a pressure limit of 2 psi (0.137 bar). It has a detachable screw terminal connector for electrical connections and zero and span adjustments can be made using an external security key pendant. The process connection is through 3/16" O.D. barbed brass fittings on a removable process head. Important technical details include a thermal effect of 0.5% FS, a loop resistance of 800 ohms max, stability of ±0.5%/yr, and a current consumption of 25 mA.
