1200°C CRUCIBLE FURNACES, TOP LOADING

CF56622C 1200°C Crucible furnaces are ideal for use in ceramics, electronics, glass, metallurgy and superconductor materials research. These models require independent controllers (ordered separately).

General Features
Requires independent controller (ordered separately, see chart)
Unitized heating and insulation element with helical wire coil imbedded in Moldatherm^® insulation for maximum heat transfer to the work load
Cover plug with Moldatherm^® insulation and handle for safe removal
Moldatherm^® insulation protects vestibule, improves energy efficiency
Platinel^® II thermocouple with 10'compensated lead wire and polarized plug for long life and accurate temperature measurement
Moldatherm^® ceramic fiber hearth plate supports load and protects furnace from spillage

1200°C Crucible Furnace, temperature range 100°C to 1200°C

CONTROLLERS

1200°C Digital, Single Set Point Controller
Control console is fully wired and includes advanced microprocessor-based digital control, a solid-state power module, on/off circuit breaker and thermocouple input jack. Includes microprocessor-based PID control (proportional, integral, derivative), single segment, single set point, 1 ramp to set point. Built-in adjustable high limit over temperature protection. Simultaneous LED display of actual temperature vs. set point. May be configured to display temperature in either °C or °F.

1200°C Digital Single Program, Multiple Segment Programmable Controller
Control console is fully wired and includes advanced microprocessor-based digital control, a solid-state power module, on/off circuit breaker and thermocouple input jack. Includes microprocessor-based PID control (proportional, integral, derivative), single program with multiple segments for ramp (up and down) and dwell (timed hold) temperature control. See page 35 for more information. Built-in adjustable high limit over temperature protection. Simultaneous LED display of actual temperature vs. set point. May be configured to display temperature in either °C or °F.

Option B Over Temperature Control (OTC)
Adjustable digital over temperature control, factory installed on selected control consoles with "B" designation; see chart. Protects furnace and load in the event of primary control circuit failure. Overrides main controller, assumes temperature control and shuts off power to furnace if high limit is reached. Manual re-set required for safety. Operates via magnetic contacts through signal from independent thermocouple.

Optional RS485 Digital Communications Port
RS485 Digital communications port available as an option. Allows controller to be connected to a PC for remote monitoring and control of the furnace. Up to 30 units can be connected to one PC. Please see page 35 for ordering information and additional options.
