      • Description
      • Attachment

        Applications

      • Building automation and air conditioning systems
      • Overpressure measurement in clean rooms and laboratories
      • Measurement of constant pressure in VAV applications
      • Dynamic filter and ventilator monitoring

        Communication

      • The digital signal Modbus enables direct connection to control / regulating systems.

        Configuration of volume flow or flow velocity measurement

      • Select a calculation formula and enter a k-factor. Both dependents on the type of ventilator or measuring probe.
      • Or create a reference volume flow or flow velocity, which is entered directly.

        • The modbus is used to set the device. Please read the exact procedure in the manual.

        Adjustable response time

      • The response time of the output signal can be variably set via Modbus.

        Easy offset calibration

      • For 985M-Modbus and 985VM-Modbus press the MODE/Offset button or set via Modbus in an unpressurized state to adjust the offset to zero. The Versions 985A-Modbus and 985VA-Modbus perform an automated zero offset compensation.

        Display

      • A red LED display shows the pressure value, volume flow or flow velocity.

        Mounting position

      • Can be mounted in any position. The zero offset calibration eliminates any possible position error.
