Analog Monitors

The simplest and most economical type of controls include our analog and mechanical indicators and switches to 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 air flow and automatically shuts down the blower motor when amperages fall outside the designated operating range. It is designed for constant speed applications.
