Questions & Answers

Q: What is the principle behind the Tally Surf Surface Roughness Meter?

The Tally Surf Meter works on the same principle as the Tomlinson Surface Meter, but it is an electronic instrument. It measures surface roughness by detecting variations in the air gap caused by the movement of the stylus due to surface irregularities.

Q: What are the advantages of using an electronic instrument like the Tally Surf Meter?

Unlike mechanical instruments, the Tally Surf Meter is versatile and can be used in any condition. It also provides more accurate measurements and can calculate and display roughness values according to standard formulas.

Q: What components are included in the Tally Surf Meter?

The Tally Surf Meter consists of a measuring head with a stylus and armature, electrical coils, a bridge circuit, an oscillator, amplifier, demodulator, filter, meter, and a pen recorder for making permanent records.

Q: How is the Tally Surf Meter used?

The meter is operated by an electric motor, which allows the measuring head to move in a linear path. As the stylus encounters surface irregularities, the armature and air gap vary, causing an imbalance in the bridge circuit. The resulting modulation output is then amplified and recorded.
