Cryogenic temperature controllers

Model 22C, Model 24C, Model 26 and Model 54 from CryoCon

The different cryogenic temperature controllers Model 22C, 24C and 26 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.

The model 54 is a four channel cryogenic impedance bridge capable of measuring resistance, inductance and mutual-inductance. Additionally, four control loop outputs support use as a temperature controller. It measures impedance by use of an auto-blancing, ratiometric AC bridge. Impedance measurement in cryogenic systems often requires low level excitation followed by precision signal recovery. To implement this, the Model 54 uses a differential voltage-mode excitation scheme followed by bi-phase lock-in detection. Differential mode excitation prevents electrical noise pickup currents from flowing through the sensor and the use of passive attenuation reduces the output impedance of the bridge, thereby reducing generated output noise. To further reduce noise, sine-wave excitation is used with programmable frequencies.
