Trummeter Belt Tension Meter
Logis-Tech (UK) are suppliers of the H&K Trummeter Belt Tension Meter.
A belt drive achieves its maximum life span when it is configured specifically
for the application, the belt is perfectly tensioned and the pulleys are precisely
aligned.
The TRUMMETER is an electronic measuring instrument that consists of a
measuring probe and a microprocessor and is used for measuring the belt
tension and checking the strand force of a belt drive.
The measurement result is displayed in Hertz, Newtons or Pounds Force. This
result can be compared with the set-point of the belt tension.
Drive-belt suppliers list this set-point value in Hertz or Newtons. It depends on
the characteristics of the drive system
Measuring the Belt Tension (Hz)
The belt frequency can be measured only when the drive has been shut down
and is stationary. Whilst still fitted, the taut drive belt must be tapped
in order to make it oscillate at its natural frequency. This static natural
frequency is then measured by the probe with the aid of pulsed light. Care must
be taken to ensure the light is reflected sufficiently by the belt.
The measured values are displayed in Hertz [Hz]. It’s not necessary to enter the
belt masses and lengths.
Measuring the strand force [N], [lbf]
To calculate the strand force, values for the frequency, the belt mass, and the
belt length are entered into the microcomputer of the TRUMMETER. The
strand force is calculated by the computer and compared with the specified
value defined when the drive was designed. The microcomputer calculates the
strand force using the formula:
