Für jede Anwendung die richtige Lösung [Translate]
The electronic airflow monitor RHEASGARD® KLGF measures the flow velocity in m/ s and converts the measurement signal to a standard signal of 0 - 10 V (relative) (flow measuring transducer). The flow sensor available with/ without an optional display.
The RHEASREG® KLSW provided with a switching output (one-step or two-step) is designed as flow sensor/ flow monitor. Fine adjustment of the measuring range end value by the user is possible with the help of a potentiometer.
The airflow monitor/ airflow sensor is used for monitoring or controlling airflows in ducts, at ventilators and dampers, for flow-dependent monitoring of humidifiers and electric heating registers according to DIN 57100, part 420, or for use in connection with DDC systems.
