DR3422 Differential Pressure Transducer
DR3422 Differential Pressure Transducer
The DR3422 is a micro differential pressure transducer, which adopts high-precision low pressure sensor to offer measuring range from -1bar up to 1bar, and output 4-20mA, 0-5 or RS485. Through high-performance MCU correct and compensate nonlinearity and temperature drift, the differential pressure sensor can realize accurate measurement of pressure signal. A LED display is optional to read the pressure on site. With a solid aluminum alloy housing, it is easy to install and operate.

FAQ
What’s the wind pressure transmitter?
Describes a pressure transducer which was specially developed to measure wind pressures exerted in buildings. The instrument, which gives an electrical output, is suitable for measuring pressure in the range of -1bar-1bar. The frequency response enables pressure fluctuations lasting only 10ms to be recorded.
What is a differential pressure transducer used for?
A differential pressure transducer is an instrument that can consistently and accurately detect a pressure drop in a pipe and then use the pressure measurement on either side to provide the differental pressure within the pipe. It output a standrad signal required by pressure control system.
What’s is the smallest differential pressure?
The smallest differential pressure is 100Pa. Common ranges include the following, 0-100Pa, 0-200Pa, 0-300Pa, 0-1KPa, 0-2KPa, 0-3KPa, 0-4KPa, 0-5KPa, 0-10KPa, -100~100Pa, -200~200Pa, -1~1KPa, -3~0KPa, -5~0KPa. If the range is out of the list, please contact us for help.
