Characteristics
The non-contacting thermal measuring device (BTM) is a monitoring system for Voith
turbo couplings.
The BTM is used to measure the operating medium temperature of Voith turbo
couplings of sizes 366 up to 1330 (measuring range: 0 °C to 180 °C).
The non-contacting signal transmission allows measuring the operating medium
temperature during active operation and to draw conclusions to the actual coupling
stress.
As the temperature is measured directly in the operating medium, changes of stress
are quickly identified allowing to quickly react to possible overloads and to prevent
excess temperatures.
The loss of coupling filling through the fusible plugs and associated downtimes can
reliably be avoided.
Please note that the BTM, like any other temperature measuring system, indicates the
temperature with some time delay.
For evaluation and further processing of the data in the machine control system, the
time delay depending on the actual heating-up velocity of the operating fluid has to be
considered.
Moreover, the input power available for machine operation can be optimally used.
Please consult Voith.
Benefits and reaction possibilities:
–Temperature warning
–Switch-off of drive motor
–Reduction of engine speed (diesel engines)
–Reduction of load intake
–Optimization of load absorption of driven machine
