Calibratable pendulum airflow sensor RHEASGARD
locking screws, with cable gland (optional M12 connector as per DIN EN 61076-2-101) optionally with / without display, with external duct probe incl.
mounting flange, to determine the flow velocity (0.1...20 m/s).
Calibratable pendulum airflow sensor RHEASGARD
locking screws, with cable gland (optional M12 connector as per DIN EN 61076-2-101) optionally with/ without display, with external duct probe incl.
mounting flange, to determine the flow velocity (0.1...20 m/s). The following parameters can be queried by the Modbus: flow velocity and volume flow
(calculated).
The flow sensors are 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 separated RS485 Modbus interface, selectable bus termination resistance, DIP switch for setting the
bus parameters and bus address in the current-free state, internal LEDs for telegram status indication, two separate push-in terminals and large
three-line display (illuminated). The sensor is factory-calibrated.
