Differential Transmitters

Senses the pressure of air and compatible gases and sends a standard 4-20 mA output signal. The housing is specifically designed to mount on a 35 mm DIN rail in a panel. Mounting style allows for several units to be mounted closely together reducing required space. The span and zero controls are for use when checking calibration.

Ideal solution for automated air conditioning and ventilation applications, this pressure transmitter measures differential pressure from -100 to 100 Pa and features analog output/supply of 4 to 20 mA (4-wire, 24 V AC/DC). In addition, it ensures optimum system function, optimizes climate conditions, and saves energy.

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.

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.
