Heating and Cooling Elements

Two different heating and heating-cooling elements are available for the Dimension Icon:

• High Temperature Heater

The High Temperature Heater element has a working range of ambient temperature to 250ºC. The consists of a ceramic body and tungsten cap enclosing a platinum resistive type heater, a “K-type” thermocouple, and a magnet. The heater is located underneath the tungsten cap, the thermocouple is located inside the tungsten cap at the center of the heater approximately 0.1 mm (0.004 inches) beneath the surface, and the magnet is located inside the heater body.

• –35ºC to 100ºC Heater/Cooler

The Heater/Cooler element includes a Delrin body with a tungsten base and cap. Internal components include a multi-stage Peltier (thermoelectric) element and a “K-type” thermocouple. This thermocouple is located directly under the tungsten cap, approximately 0.5 mm (0.020 inches) from the surface. The Heater/Cooler element does not incorporate a magnet.

The high temperature heater and heater/cooler elements plug into the connector on top of the Heater/Cooler Magnetic Base. The five contact pins on the bottom of both the High Temperature Heater and Heater/Cooler elements include two thermocouple leads (large pins), two heater leads (two outer small brass pins), and one bias voltage lead to the cap (center small brass pin).

Copper Ring

The copper ring is used to extract heat from the heater/cooler during reduced temperature experiments.
