These pressure transmitters allow for several units to be mounted closely to sense and signal the difference in pressure between 2 ports. They are used for filter monitoring, pressure indication, static pressure in ducts or buildings and to sense building pressure.
The Testo 6351 pressure transmitter for differential pressure enables measurements in the 50 Pa to 2,000 hPa measuring range. A particularly outstanding feature of the transmitter is the automatic zero-point adjustment, which ensures high accuracy and long-term stability.
Testo 6381 differential pressure transmitter with calculation of flow velocity and optionally with humidity/temperature, accuracy ±0.5% of measuring range final value, automatic zero-point adjustment, selectable measuring range between 10 to 1000hPa, selectable signal outputs, optional display, output of all relevant pressure, flow and humidity paramters.
Testo 6383 differential pressure transmitter in cleanroom-conform panel design, optionally with humidity/temperature, accuracy ±0.3% of measuring range final value, automatic zero-point adjustment, selectable measuring range between 10 to 10hPa, selectable signal outputs, optional display, output of all relevant pressure and humidity parameters.
Monitors differential pressure of air and compatible gases and liquids with 0.5% accuracy. The design employs dual pressure sensors converting pressure changes into a standard 4 to 20 mA output signal or field selectable voltage.
Microprocessor-based high performance transmitter, which has flexible pressure calibration, push button configuration, and is programmable using HART® Communication. The multiplanar design simplifies installation, saving you time and money during set up.
