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).

TECHNICAL DATA

Differential pressure measurement in HVAC applications
Air flow volume measurement ** in HVAC applications
Air flow velocity measurement (by using an external PSET-PT X-200 Pitot tube
connection set) in HVAC applications
Differential pressure/airflow monitoring in clean rooms
Clean air and non-aggressive, non-combustible gases
Built-in digital high resolution differential pressure sensor
Air flow velocity can be measured via Modbus RTU (by using an external PSET­PTX-200 Pitot tube connection set)
Selectable analogue / digital output: 0—10 VDC / 0—20 mA / PWM (open collector type):
0—10 VDC mode: min. load 50 kΩ (RL ≥ 50 kΩ)
0—20 mA mode: max. load 500 Ω (RL ≤ 500 Ω)
PWM mode: PWM Frequency: 1 kHz, min. load 50 kΩ (RL ≥ 50 kΩ)
Variety of operating ranges and measurement windows
Minimum differential pressure range span: 50 Pa
Minimum volume flow range span: 10 m3/h
Minimum air velocity range span:1 m/s
Selectable response time: 0,1—10 s
Implemented K-factor
Selectable internal voltage source for PWM output – 3,3 or 12 VDC
Differential pressure, air volume** or air velocity readout via Modbus RTU
Selectable minimum and maximum operating ranges
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. 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
