    Description Intended Use Types 461 and 462 are general purpose laboratory furnaces intended for applications requiring temperatures from 800-1700 degrees C. NOTE General Usage The fans operate continuously, even Do not use this product for anything other than its when the circuit breaker is OFF, to assure intended usage.

  • Page 8: Types Of Controllers

    ESCRIPTION The control section consists of a temperature controller, a current controller, a transformer, a contactor (relay), a circuit breaker, and a pilot light. The temperature controller senses the furnace temperature (by means of the thermocouple) and adjusts electricity to the heating elements by means of the current controller.
