Cryogenic temperature control
Cryogenic temperature control equipment is used to monitor and regulate the temperature of a device at low temperatures down to a one Kelvin or even below. For this task we offer cryogenic temperature controllers with up to four multi-purpose input channels, which support most temperature sensors (silicon diode, ruthenium oxide, platinum RTD, Cernox, rhodium iron, germanium, Carbon-Glass, GaAlAs diode and thermocouple), cryogenic temperature monitors with up to eight input channels supporting diode, platinum RTDs and all other cryogenic resistor temperature sensors, including an optional dual thermocouple input, as well as silicon diode and platinum RTD temperature sensors together with cryogenic accessories like heater, heater wires and low thermal conductance cables.
The different cryogenic temperature controllers Model 22C, 24C, 26, 32 and 54 feature two or four multi-purpose input channels, which support most temperature sensors (silicon diode, ruthenium oxide, platinum RTD, Cernox, rhodium iron, germanium, Carbon-Glass, GaAlAs diode and thermocouple). They cover a temperature range from 200 mK to 1500 K. Different interfaces (Ethernet, RS-232, GPIB, USB and LabView) together with advanced operation software assure an easy integration into your measurement setup.
We offer cryogenic temperature monitors with eight, four and two independent multipurpose input channels, supporting silicon and GaAlAs diode sensors, platinum, CLTS and Rhodium-Iron RTDs, Negative-Temperature-Coefficient (NTC) resistor sensors and all other cryogenic resistor temperature sensors, including an optional dual thermocouple input. The low temperature monitors offer built-in sensor calibration curves that support most industry standard low temperature sensors. Additionally, eight user calibration curves are available for custom or calibrated sensors. Each user curve may have up to 200 entries. The temperature range (between 500 mK and 1200 K) depends on the sensor type. The controller offers a wide variety of standard remote interfaces including Ethernet and RS-232. GPIB and USB are optional. LabView drivers are available for all interfaces.
Heaters are needed to actively control a temperature inside a cryostat. They work best in combination with the temperature controller from CryoCon. To contact heaters and sensors in a low temperature environment, it is important to use special materials suitable for these temperatures. Good electrical conductivity paired with poor thermal conductivity materials are here the materials of choice, like phosphor-bronze.
