Measurement Controllers

Thickness Monitors TM13 & TM14


The TM13 and TM14 devices comprise: quartz oscillator, frequency measuring system and communication interface. It is connected to the input element of a quartz resonator. The measurement results are transmitted via RS232 to the master device: either a PC or TMC13 controller.

Features TM13

  • Frequency Resolution: 0.1 Hz
  • Number of measurements per second: 4 (fixed)
  • Maximum frequency of quartz oscillator: 6 MHz
  • Stability: 0.5 ppm

Features TM14

  • Frequency Resolution: 0.01 Hz
  • Number of measurements per second: 0.5, 1, 2, 4, 10 (selectable)
  • Maximum frequency of quartz oscillator: 6 MHz
  • Stability: 0.5 ppm

Remote control via TMC13 controller or PC.


- Communication interface RS485 (specify at order)
