Description

Air flow monitor RHEASREG® PLSW-W24
Electronic pendulum airflow monitor RHEASREG® PLSW with switching 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 (0.3...65 ft/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.
