Cryogenic temperature controllers

From Lake Shore Cryotronics

Temperature controllers for cryogenic applications are based on closed loop PID control. Also often called feedback control. With the help of this feature the temperature controllers from Lake Shore Cryotronics cover a low temperature down to 100mK and up to 1.500K. The control loops feature up to 100W heater power output. In the feedback control mode, the controller attempts to keep the load at exactly the user entered setpoint, which can be entered in sensor units or temperature. To do this, it uses feedback from the control sensor to calculate and actively adjust the control (heater) output. The control algorithm used is called PID.

Features
  • 100mK to 1.500 K temperature range
  • Up to 4 PID-controlled outputs with up to 100W
  • Wide range of supported temperature sensors
  • Ethernet, USB and IEEE-488 interfaces
