Dwyer 685-06 Differential Pressure Transmitter is a reliable and accurate device for measuring pressure differentials. With a temperature range of -4 to 158°F, it can handle a variety of environments. The device has an accuracy of ≤ ±0.5% RSS and a response time of 1s. It is enclosed in an IP54 rated enclosure and features a piezoresistive pressure sensor. The transmitter has a humidity range of 0 to 95% RH and offers multiple electrical connection options. The output signal can be either 4-20 mA or 0-10 V, depending on the wiring configuration. The device is suitable for air and non-corrosive gases and is constructed with durable ABS material. It has a loop resistance of 500 Ω max for 2-wire configuration and ≥ 1 kΩ for 3-wire configuration. The transmitter is compact, with dimensions of Ø 66 x 28 mm, and provides stability of ≤ ±1% RSS per year. It comes with a 6mm hose connection and a cable conduit made of polyamide. The maximum current draw is 21 mA for 2-wire and 40 mA for 3-wire configuration.
