Continental ContiTech TensionRite® Belt Frequency Meter is
a two-component system consisting of a hand-held meter
attached to an optical sensor via an electronic cable. The
sensor uses an infrared beam to detect the vibration of a belt
strand and sends a signal to the meter. (The sensor
includes an LED that produces an orange light beam to help
aim the invisible infrared ray.) Comparing this input to the
vibration of a quartz crystal, the meter computes the natural
frequency of the belt. The result is shown in the display
window as hertz (oscillations per second). The internal
programming of the meter is also able to report the belt tension
in units of force (either newtons or pounds-force) provided the
operator has entered the belt mass and span length using the
manually operated key pad.
The meter operates on four AA batteries. Battery life is
approximately 20 hours. The battery compartment is
accessible at the back of the meter.
An abridged manual, a tuning fork for checking calibration
and a storage case are included with the complete kit.
