PRODUCT DESCRIPTION
ARTICLE CODES
e HPS-X -2 series are high resolution differential pressure transmitters with
Modbus RTU communication, which are equipped with a fully digital pressure
transducer designed for a wide range of applications. Air flow velocity readout is
available by connecting an external Pitot tube connection set. All parameters are
accessible via Modbus RTU (3S Modbus software or Sensistant).

* In case of 3-wire connection, the analogue output GND signal is internally connected with the GND of the power supply. erefore, G and F-type devices
cannot be used together in the same network. G and F-type devices must be supplied with separate power supplies. Do not connect the GND terminals of G
and F-type devices together!
** Only when K-factor of fan / drive is known. If K-factor is unknown, air volume flow can be calculated via multiplying the duct cross-sectional area (A) by the
air flow velocity (V) using the formula: Q = A * V
