The steel wheel construction is designed for standard HVAC operating temperatures and provides better structural integrity than plastic or thin-gauge aluminum wheels in light industrial use

metallized polypropylene dielectric film to maintain capacitance stability across a broad thermal operating range of -40°C to 70°C

if power is present but the wheel is seized or the motor only hums

this transmitter offers the ruggedness and repeatability required for industrial environmental control
