 Advantages
1 Principle of detection: Punch force exerted on rollers and the roller force is
measured by the sensor. No need for conversion of the signal. The value displays
on the screen directly
2 German Tedea-Huntleigh gravity sensor;
3 The sensor is installed directly below the roller center with capacity to 10T .
Detect directly. Because it is located under the roller center detection errors can
be avoided. The result is increased accuracy in filling dosage and even tablet
weight
Easy changing and calibration can be completed in the field
Not effected by time and temperature
Easy to test and verify.
Multi-detection for each punch guarantees precise pressure when compared with
traditional strain gauge type pressure transducer
