Dwyer 668C-18 is a compact and reliable differential pressure transmitter. With an accuracy of ±1% FS, it ensures precision in measurements. Its quick response time of <60 msec enhances efficiency. The fire retardant glass filled polyester enclosure guarantees safety, while the terminal strip electrical connections simplify installation. Operating on a voltage range of 12 to 30 VDC, this transmitter provides a 4 to 20 mA, 2-wire output. Designed for air and non-conductive gases, it can handle pressure up to 10 psig (0.69 bar). With a low thermal effect of 0.033% FS/°F (0.18% FS/°C), it allows for accurate readings across temperatures. The 3/16" OD fitting for 1/4" ID tubing ensures easy and secure connection.
