Voice coil temperature meter

OMT-405 5ch Voice coil temperature meter

This equipment measures the voice coil temperature of at most 5 loudspeakers.Signal source corresponds to all kinds of signals in the reach of the 20kHz from 20Hz(sine wave, white noise, pink noise, standard load test noise and music source).

A measurement item indicates a chart and the value to time between the temperature and the input voltage.


 

OMT-404 DC Voice coil temperature meter

Model OMT-404 is a temperature meter to measure the temperature of voice coil of the speaker unit applying the DC voltage.
This model displays temperature, DC resistance, and input voltage value for measurement result of the voice coil at the same time with digital. And also the measured value is stored in the USB flash drive at constant time interval.
Notice : DC power supply are not included this model.


OMT-205A Voice Coil Temperature Meter

 OMT-205A is designed to measure the temperature of the speaker voice coil while in operation.
Measurement can follow the signal source of sine waves, white noise, pink noise, or music source in the frequency range from 20 Hz to 20 kHz.
 The measured temperature and the input voltage are simultaneously displayed on digital displays. Two DC output terminals are prepared to record the temperature and the input voltage simultaneously.

Optional unit : Data Recorder Model OT-1009


OMT-205AH Voice coil temperature meter

 When OMT – 205 A including OMT-205AH system was modified , this system input signal of 600Vp-p using AP-1203.
Measurement can follow the signal source of sine waves, white noise, pink noise, or music source in the frequency range from 20Hz to 20kHz.

  The measured temperature and input voltage are simultaneously displayed on exclusive digital displays. For recording of the changing input voltage and temperature, two DC output terminals are provided and simultaneously recorded to show the relationship between the two.

・This unit can use BTL power amplifier as well as single-ended power amplifier.

Optional unit : Data Recorder Model OT-1009

OMT-205AH


OT-1009 Data Recorder

Data recorder OT-1009 can record and display voice coil temperature measured by voice coil thermometer OMT-205A, OMT-205AH or OMT-105A (discontinued) and loudspeaker drive voltage.
This product can connect 8 voice coil temperature devices.
