Economical Mahr Federal Series 830 Gaging Amplifier Provides Benefits Of Analog Display

Designed to provide a low-cost alternative to all-digital gaging amplifiers, newly enhanced Series 830 Analog Gaging Amplifiers from Mahr Federal feature dual input ports for single or differential ID or OD measurements with selectable ranges in inch or metric units. They are now available for use with "Federal" or "Mahr" type inductive probes. Portable or bench mountable, the high performance Series 830 amplifier is rugged and equally at home on the shop floor or in the laboratory.

"Even though we live in a digital world, analog displays still offer advantages in a number of applications," said Paul Mailloux, Manager Precision Gages for Mahr Federal. "Analog indicators instantly reflect true measurement size. They're easier to use than digital instruments and can more readily detect trends or rates of change."

Common applications include: part centering and leveling on machine tools; exploring a surface for defects on a surface plate; detecting part out-of-roundness on a V-block; and machine leveling using level sensors. With excellent response and performance characteristics, Series 830 Amplifiers are an outstanding choice for both dynamic and static gaging applications.

The 830 Series includes a dimensional-measuring model calibrated in both inch and metric units, and a model that supports both leveling and dimensional applications in arc-seconds and inches. Both models offer three measurement ranges and resolutions suited to most setup and inspection tasks.

Series 830 Amplifiers can be bench mounted or portable. A tilt base provides stable support and easy adjustment of viewing angle. All controls are located on the front of the cabinet. Specific models are available for use with "Federal" or "Mahr" full-bridge LVDT inductive probes.

Two gage inputs can be used simultaneously with polarity either normal or reversed for differential measurement setups. Calibration adjustment is available for each input, and a ±2 volt analog output port is also provided. Rechargeable batteries provide a minimum of eight hours of continuous use, and the system also operates on 120 or 240 AC line voltage.
