Differential Pressure Gauge – Beck 990 Series


  • Adjustable response time
    The response time of the output signal can be configured using the menu in a range from 0.1 to 20 s.
  • Easy offset calibration
    The output signal of the type 990M can be re-calibrated to zero in the menu when the instrument is in a pressure less state. The series 990A performs an automated zero offset
  • Volume flow measurement
    The shape of the output signal can be changed in the menu from linear to square rooted to enable a volume flow measurement via a differential pressure reading.
  • Switching output
    The differential pressure transmitter offers two adjustable potential-free switching outputs with a maximum switching capability of 50VAC/5A (S1) and 250VAC/5A (S2).
  • Measuring method
    Piezoresistive pressure transducer.
  • Mounting position
    Can be mounted in any position. The zero offset calibration eliminates any possible position error.

Differential Pressure Gauge 990 from 0 bis to kPa.

The differential pressure gauges 990 Display are for air and non-aggressive gases and will be used to measure differential pressure, overpressure and vacuum. They offer one adjustable pressure range and two output signals, which can be selected in the menu. The type 990M has a manual zero offset calibration, the type 990A has an automatic zero offset calibration. Monitoring of air and non-aggressive gases.


  • Monitoring of air and non-aggressive gases.
