Thickness Monitors Controller TMC13

Newest technology electronics designed for monitoring and controlling any coating and deposition processes. Up to six channel inputs and two additional vacuum gauge channels together with 7″ TFT display make this unit really unique and universal.



Prevac are a world leader in the design and production of analytical and deposit scientific and research equipment. Their systems operate in a high and ultra high vacuum environment. They design and construct UHV and HV systems fully adapted to the individual requirements of research projects and industrial applications.

Key Features

  • Up to 6 channels for thickness monitor sensors with quartz balances
  • 2D real time chart module
  • Two inputs for most active vacuum gauges
  • Up to 8 shutters and I/O reprogrammable
  • Up to 8 shutters and I/O reprogrammable
  • Rwo reprogrammable analogue outputs for rate and thickness monitoring with 16 bits resolution
  • Industry standard 6 MHz Crystal
  • Frequency resolution: 0.1 Hz (TM13) or 0.01 Hz (TM14)
  • Operation of up to two multi-crystal sensor heads (pneumatic or stepper motor)
  • Compact design
  • One-touch material change
  • Favourites list for frequently used materials
  • One-touch units change
  • Save individual user profile
  • Built-in video tutorials
  • LabVIEW libraries


Sensor inputs can be assigned to different materials with individual parameters as well. High speed and high accuracy measuring process controlled by the DSP processor improves the film quality and repeatability. It also brings features of accuracy, stability and instrument configuration. Autosave function for saving your parameters/unit pre-set and applying them automatically after restart.

Available software dedicated to precise rate measurements. Registers changes in the frequency of the quartz resonator in time (in the form of a graph). Allows the user to calculate the evaporation rate from the selected time interval. Suitable for e.g. MBE applications.
