HVAC (Heating, Ventilation, Air-Conditioning) industry.
PascalMaxx pressure sensor.
| Model | Description |
|---|---|
| PascalMaxx 500 Z | PascalMaxx pressure transmitter. 0 - 500 Pa |
| PascalMaxx 2000 Z | PascalMaxx pressure sensor. 0 - 2000 Pa |
Accurate, reproducible and stable measurement.
Mechanical quality - robust, compact housing.
Long-term stability - automatic zeropoint calibration.
Big LCDisplay - very good readable.
Maintenance free - low operational costs
These measurement devices detect the differential pressure with a membrane sensor, which measures
the differential pressure by a mechanical strain due to the pressurisation. In order to get an optimal
longterm stability the sensor is calibrated automatically and periodically during its operation.
This allows to achieve the best accuracy, reproducibility and stability.
Range of use:
The PascalMaxx membrane differential pressure sensors are suitable for medium pressure ranges
between 200 and 2000 Pa.
The automatic zeroing allows a maintenance free and reliable use and offers a real added value for
the operation of HVAC plants.
