PRODUCT DESCRIPTION

The 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).

■

Modbus registers reset function (to factory pre-set values)

 

■

Four LEDs with light guides for transmitter status indication

* In case of 3-wire connection, the analogue output GND signal is internally connected with the GND of the power supply. Therefore, 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
