RHEASGARD KLGF xx ⁄ RHEASREG
Electronic duct air flow sensor RHEASGARD
housing made of impact-resistant plastic with quick-locking screws, with cable gland,
with/without display, to determine the flow velocity (0.1...20 m/s).
The measuring transducer converts the measurement signal into a standard signal of 0 - 10 V.
Electronic duct air flow sensor/monitor RHEASGARD
with active and switching output, housing made of impact-resistant plastic with quick-locking screws,
with cable gland, to determine the flow velocity (0.1...20 m/s) and temperature (0...+50 °C).
For device type KLGFVT , the calculated volume flow parameter can be retrieved as an alternative to the flow
(configurable on the display). The measuring transducer automatically detects the required output type and
converts the measurands into the required standard signal of 0 - 10 V or 4...20 mA (Automatic Output Switching).
Electronic duct airflow monitor RHEASREG
housing made of impact-resistant plastic with quick-locking screws, with cable gland,
with/without display, to determine the flow velocity (0.1...20 m/s).
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.
