Digital Torsion Meter for lamp cap test force

 

 

Description:

Lamp cap Torsion Meter is a newly developed intelligent product with microprocessor built-in.The digital torsion meter is a mechanical strength safety requirement of the lamp cap which has been taken into account by most lighting manufactures and is also compulsively required by all the nations. Thus we developed the digital torsion meter with the reference of the IEC. It meets the requirement for the measurement of lamp cap torque force test of the quality inspect de-partment and manufactures.

 

Characteristics:

1) It can measure the clockwise and anti-clockwise torque of lamp cap. And it can preset upper limit alarm. Auto save data after system shutting down.

2) Instrument has the function of zero point calibration. The zero point is very steady. Instrument uses 4 digits of number to display. So it is of high accuracy and high stability.

3) Double watchdogs designed inside to ensure the instrument high reliability and will not shut down under complicated environment.

4) Instrument is convenient to be used because of several clamps of lamp caps such as E27/E26, B22d, E14/E12, G13/G5 and so on.

5)Fixing with clamp. Rotating the lamp, the positive and negative torque rate will be recorded.
6)Torque range: 0-10N*m (special range is customer-tailored).
7)High performance in reliability, precision and longevity by adopt strain gauge torque sensor
8)Peak torque holding function, upper limit can be set for alarm.
9) Conform to Chinese and international standard.

Basic Principle

The equipment is consisted by torsion device and secondary meter. The key for accuracy is the

torque sensor. The equipment adopt strain type torque sensor with the features of high reliable,

cost-effective, high accuracy and long life.

In sensor on the elastomer labeled resistance strain gage and composition Wheatstone bridge. Power

the bridge with driving voltage, under the action of the torque, the elastomer will deform and the

strain gage will change, so that the bridge will imbalance and there is a linear voltage signal

between bridge output and torsion. The secondary meter will be amplified the voltage signal, and transform the signal by A/D transformer, and then send to the microprocessor for data analysis and

display. Functional block diagram as following:
