Designed for constant speed applications, the Analog Monitor is the simplest and most economical type of control. By monitoring the amperage and air flow of your blower, the Analog Monitor can detect and protect the blower and motor from mechanical surge and overload, high blower bearing temperatures, and high blower (or blower bearing) vibration.
The HOFFMAN & LAMSON Analog Meter Relay monitors motor amperage and airflow and automatically shuts down the blower motor when amperages fall outside the designated operating range.
Our Meter Relay is available in a single setpoint configuration for low amp set point surge monitoring or a dual set point for low and high amps surge and overload setpoint monitoring.
For blower vibration monitoring, a single Vibration Switch is available for mounting on the blower housing or bearing. When alarmed, contacts contained in the switch open (or close).
