Differential pressure
sensor
For air and non-aggressive gases, with calibration certificate.
• Calibration certificate from the factory
• High degree of measuring accuracy
• Pressure-linear characteristic curve
• Operating voltage AC 24 V / DC 13.5...33 V or DC 11...33 V
• Output signal DC 0...10 V or 4...20 mA
• Simple and fast mounting thanks to integrated fixing angle bar in the
housing
• Calibrated and temperature-compensated measuring signal
• Excellent long-term response

• Display* indicates the present differential pressure
*
Depending on type
The differential pressure sensor acquires differential, over and under pressure of
air and nonaggressive gases if a high degree of measuring accuracy and quality is
required as well as a requirement for a calibration certificate.
Fields of application:
• Measuring slightest differential pressures in ventilation and air conditioning ducts
• Check air flows
• Monitor filters and control fans
• Pressure supervision in labs, production, storage and clean rooms
• For acquiring variable air flow in VAV plants on the supply and extract air side
