Specification
Maximum temperature 1000oC Usable dimensions 50mm
diameter x 100 deep. Heating element Yttria stabilised iron chrome aluminium
alloy resistance wire wound around an IAP ceramic tube. Temperature sensor
NiSil/ NiNiCrSil thermocouple Type N mineral insulated. Door type Right hinged
lid. Door switch The nature of the test requires the heating element to remain
on when the furnace lid is open, so no door switch is fitted. As a safety
measure, a 30mA residual current circuit breaker is built into the furnace.
Controls The furnace is offered with a choice of different PID digital
temperature controllers. Over temperature protection Available as an optional
extra. Using an independent thermocouple, a Eurotherm controller operates a
contactor to shut down the furnace until manually reset. Power control
Encapsulated solid-state relay with zero voltage switching control and over
voltage spike protection.
