Mahr Federal Maxum III Digital Transducer, Pencil-Style, 0.375" Body Diameter, Short Range

The Mahr 2033099 pencil-style digital transducer has a measurement range of +/- 0.040" (+/- 1.0mm) and is intended for use with Millimess series Maxum III remote indicating units (sold separately). The probe has a 0.375" body diameter and uses replaceable M2.5 thread contact points. This pencil-style digital transducer meets Ingress Protection (IP) 54 standard for protection from dust and water, and is suitable for use in measurement applications such as evaluating a machined surface.

Indicator gauges, also called gages or dial indicators, are precision instruments that measure short linear distances. They are commonly used for detecting deviations from tolerance limits, such as the amount of surface distortion, or runout, on a round or cylindrical workpiece. They have two styles: digital indicator gauges and dial indicator gauges. Digital indicator gauges use an electronic sensor and display measurement through an LCD or other digital display. Dial indicator gauges measure through a spring-loaded plunger driven into its shaft. The pointer on the dial display marks the degree the plunger is depressed, while an additional turn counter may track the number of times the pointer has spun around the dial. For all types of indicator gauges, runout is typically measured when the tip of the plunger (the point) is held perpendicular to the rotating workpiece. Indicator gauges are typically used in manufacturing, machining, and mechanical engineering.

Mahr Federal manufactures dimensional metrology instruments and metering systems. The company, founded in 1861, is headquartered in Goettingen, Germany.
