Differential Pressure Gauge – Beck 990 Series

Features

  • 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
    compensation.
  • 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.
