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.
Designed to measure pressures as low as 0.1 in w.c. with ±0.4% accuracy. The transmitter features 15 psid overpressure, reverse polarity protection and EMI/RFI protection. The NEMA 4 housing allows for versatile mounting locations and integral mounting tabs simplify installation.
Provides a 4 to 20 mA process output, a robust NEMA 4X enclosure, plus a large LCD display that can be programmed to read in pressure, velocity or flow. Features security level, English or Metric engineering units, pressure, velocity or flow operation, K-factor, volumetric flow operation, plus many more.
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.
