RHEASGARD KHSSFV-Modbus
Electronic duct top-hat rail air flow sensor RHEASGARD
boxes or control cabinets with 35 mm mounting rail, external flow probe incl. mounting flange, for determining the flow velocity (0.1...20 m/s).
The following parameters can be retrieved from the Modbus: Flow velocity and volume flow (calculated).
The flow sensors is suitable for monitoring or controlling airflows in ducts, at fans and dampers, for flow-dependent monitoring of humidifiers and
electric heating registers according to DIN 57100, Sect. 420, or for use in connection with DDC systems.
Innovative Modbus sensor with galvanically isolated RS485 Modbus interface, switchable bus terminating resistance, DIP switch for setting the
bus parameters and bus address in current-free state, LEDs for telegram status display. The sensor is factory-calibrated.
