Belt Tension Testers
SONIC TENSION METER WITH CORD SENSOR
Model 507C
shown with Cord Sensor
FAST, ACCURATE TENSION READINGS
EASY TO USE
COMPACT & LIGHT
Testing tension with a spring tester requires muscle, a
piece of string and at least three hands! The Sonic Ten-
sion Meter works on the theory that belts, like strings,
vibrate at a particular natural frequency based on mass
and span length. The meter converts this frequency into
a measurement of tension.
To test tension:
1. Enter belt mass constant, belt width & span length
into meter.
2. Hold meter to belt span, then strum belt to make it
vibrate. The meter will measure the vibration and
convert into belt tension.
Features:
• Output reading measurable in hertz, pounds,
kilograms and newtons.
• Frequency range from 10-5000 hertz.
• Variable frequency range filters.
• Auto gain control automatically adjusts meter
sensitivity.
• 20 memory registers for belt constants.
