Dwyer 668-3 Differential Pressure Transmitter is an accurate and reliable component that operates in a temperature range of 0 to 150°F (-18 to 65°C). It offers an impressive accuracy of ±1% FS (RSS), including non-linearity, hysteresis, and non-repeatability. With a response time of less than 60 msec, it provides fast and efficient performance. The enclosure is made of fire retardant glass filled polyester, ensuring safety. It features terminal strip electrical connections for easy installation. The transmitter allows for zero and span adjustments of ±1 mA, without interaction. It operates on a voltage range of 12 to 30 VDC and provides a 4 to 20 mA, 2-wire output. Designed for air and non-conductive gases, it has a pressure limit of 10 psig (0.69 bar). The thermal effect is minimal at 0.033% FS/°F (0.18% FS/°C). It can be connected using a 3/16" OD fitting for 1/4" ID tubing and has a loop resistance of 0 to 800 Ω.
