Low-Cost Digital Amplifier Provides Clear Readings for High-Precision Measurements

Mahr Inc. has introduced the new Millimar C 1202, a full feature, configurable, low-cost, digital length evaluation amplifier for high precision measurements in the inspection or production environment.

The C 1202 features a high-resolution, high-color contrast display that provides clear and very responsive analog readings with selectable scales. The compact instrument is versatile and suitable for use with a variety of sensors.

The Millimar C 1202 is user configurable with the use of Mahr's N 1700 series amplifier modules. Modules are available for LVDT inputs in both standard and high-resolution capabilities; pneumatic inputs for air tooling; and input modules for digital encoders. The Millimar C 1202 will allow for up to two inputs and provides the capability of displaying up to three measurement results.

Depending on the input module used, the display range can be up to ±5000 µm with reading resolution of 0.1 µm. When combined with Mahr's N 1702-HR high-resolution module, the range becomes ±200 µm with reading resolution of 0.01 µm. Users can view the analog scale, numeric digital readings, or both and the display may be adjusted to the ideal viewing angle (0° to 90°). The C 1202 unit can also be wall mounted.

"A major design goal for the new C 1202 was to build upon the success and features of the Millimar C 1200 which was a breakthrough high-value amplifier that produced a digital display that perfectly simulates the smooth motion of an analog meter," said George Schuetz, Director Precision Gages for Mahr. "This fast response is ideal for exploring part deviations common with surface plate measurement applications and has been carried over into the C 1202. However, the new C 1202 multiplies the input capabilities, providing the ability to do multiple input applications such as differential measurements, tapers and taper angles."
