WissEl - Wissenschaftliche Elektronik GmbH - TR-50 Temperature Controller

TR-50

Temperature Controller

The temperature controller TR-50 is designed for controlling the temperature of samples in the Mössbauer cryostats MBBC-HE0106 and MBBC-H20106.
A silicon diode DT-670 inside the cryostat is used as temperature sensor.

FEATURES

Minimum programmable temperature: 1.4 K
Maximum temperature approx. 350 K depending on technical features of the used cryostat
Four-wire connection to the sensor diode for precise temperature measurement
Short thermal response time of the silicon diode due to the small physical size
DC output for the heating device
Built-in temperature control module EUROTHERM 3216 with many programmable functions
Setting temperature control parameters via push buttons at the front panel of the EUROTHERM module
Remote control by an optional software (setting temperature control parameters and reading measuring values) via RS 232C serial interface
