Temperature Controller

Temperature controller interface

The optional PC control module

Optional Eurotherm 3000 

  • Standard temperature controller:
    • Proportional–integral–derivative control (PID control) and auto-tune function
    • 30 segments programmed with ramping, cooling, and dwelling steps
    • Built-in over-temperature alarm and thermocouple failure alarm
    • +/- 1 ºC temperature control accuracy
    • Default DB9 PC communication port (PC control module and software are sold separately. See optional.
  • Optional:  
  • MTS-02 PC control module (also including cable and software) is an add-on option for PC control.
    • It is recommended to purchase the module together with the furnace. We install and test it before shipping. 
    • It is recommended to purchase the laptop (with software pre-installed) from us to avoid software conflict.
    • Please note the module is not sold solely in the future.
  • Eurotherm 3008 Temperature Controller with +/- 0.1ºC accuracy is optional for an additional $950 including installation and testing. This package also includes the communication cable (RS485 - USB) and software CD. Click here to view the full spec.

Processing Tube

  • 99%High purity Al2O3 Ceramic, ID: 54mm; OD: 60 mm x Length 850 mm
  • Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating)
  • You may consider using a tungsten wire to hang up a crucible or sample to quench sample ( click Pic right to learn )

Vacuum Sealing and Valve

Electromagnet Sample Release Flange & Quenching

  • Full automatic electromagnet sample release flange
  • The hinged plate hooks the cable, which pulls the sample.
  • The hinged plate drops when the electromagnet powers off. The sample and the cable fall into the quenching tank.
  • Rings are available for hanging the tube block with cables.
  • The bottom flange is connected with a 4" gate valve ( manual operated ) via CF-100 adaptor
  • The gate valve is connected with a quenching media container in size 400 x400 x 200 H ( mm )
  • Caution: You must use ice water or cooled oil as a quenching media if quenching under a vacuum.

 Quenching operation

  • One stainless steel tank is located on the bottom of the furnace to contain quenching liquid.
  • One large gate valve is built on the bottom tube
  • One electromagnet is installed on the top flange and holds sample hanging wire up to 500 g
  • Touch the release button of the electromagnet on the temperature control unit, the sample will drop into the liquid tank.
  • Before release, the sample must fill argon gas to  5 psi and open the gate valve

Gas Purification and Circulation

  • EQ-RMP-1 is automatic recirculating moisture and oxygen purification system, which can provide an environment with moisture and oxygen concentrations lower than 1 ppm for MTI's furnaces and gloveboxes. 
  • Two columns of Molecular sieves are Built-in in into the system. One is for removing oxygen and another is for removing moisture up to < 1 PPM
  • The automatic pressure control system is built in to keep the pressure at a constant level
  • 6" color PLC touch panel is included which can set and display the humidity and pressure level
  • The oxygen sensor and moisture sensor are included. 

Hermetic Quenching Tank

  • A hermetic quenching tank is optional for air-sensitive materials, which enables the entire quenching process under atmosphere control
  • Please contact MTI for further inquiries.

MoSi2 heating element is used in high temperatures under an oxidizing atmosphere. During the oxidizing process, the SiO2 protective film is formed again the heating element from melting during sustained use. The MoSi2 heating element must not be used at the temperature between 400 oC and 700 oC for a long time, otherwise, the element will be cremated under the strong oxidizing atmosphere at low temperatures.
