Digital Temperature Control System ER 4131VT

The Digital Temperature Control System, ER 4131VT, makes use of liquid or gaseous nitrogen as coolant. The accessible temperature range is 100 K to 500 K. The base system consists of the following parts:

  • Quarz Dewar ER 169DIS
  • Dewar Insert Holder
  • Digital Temperature and Gas Flow Control Unit
  • Thermocouple
  • Transfer Dewar
  • 10 l storage dewar
  • Nitrogen Evaporator
  • Heater Assembly

 

 

With the dewar insert holder, the dewar is mounted to an X-Band waveguide-type cavity. The sample is inserted into the quarz dewar. Sample exchange at any temperature is a standard feature of this system.

The digital control unit monitors and controls the temperature measured with the thermocouple close to sample's position. The target temperature is reached and stabilized via PID temperature control (proportional, integral and derivative).  

The control unit is fully remote controlable via the acquisition software Xepr or WinEPR Acquisition of the ELEXSYS and EMX spectrometer series.

A Manual Control Unit (ER 4131-1030) is available for manual control of the heater and the gas flow.
