Air flow monitor
RHEASREG® PLSW-W24
Electronic pendulum airflow sensor RHEASGARD® PLGF with active output,
housing made of impact-resistant plastic with quick-locking screws, with cable gland, with/without display,
with external duct probe incl. mounting flange, 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 pendulum airflow sensor/monitor RHEASGARD® PLGFT (without display) and PLGFVT (with display) with active and switching output, housing made of impact-resistant plastic with quick-locking screws, with cable gland, with external duct probe incl. mounting flange, to determine the flow velocity (0.1...20 m/s) and temperature (0...+50 °C). For unit type PLGFVT, 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).

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.
