Operation

VIBRATION RESISTANT - AMOT Model 8254 High Temperature Switch are specifically designed for use on vibrating equipment such as heavy duty engine, compressor, pump and other industrial applications. They are suitable for control, safety and waring systems on both mobile and stationary engines, generator sets, irrigating and sprinkler systems, air and gas compressors, turbines, pumps, marine systems, machine tools, injection molding machines, etc.

RANGE - a singe range, field-adjustable from 130° to 500°F (54° - 260°C).

UNIQUE UNION - a unique union nut connects the switch housing to the temperature sensor allowing the sensor to be installed in tight quarters or the switch to be easily swiveled to align with conduit connections. Once tightened, it provides a rigid connection between the switch and the sensor well.

RUGGED SWITCH HOUSING - precision cast aluminum with a backed enamel finish. Full gasket seals provide a raintight unit designed to meet Enclosure 3 requirements of NEMA 4, UL, and CSA.

STAINLESS STEEL WELL - suitable for immersion in most fluids and gases.

BIMETALLIC STAKED DISC temperature sensor permits reliable operation over a wide range of temperatures.
