Mahr's new digital micrometer Micromar 40 EWRi, is now integrated with the company's wireless data transmission capability.

The new 40 EWRi is the latest addition to Mahr's Integrated wireless family of products, including digital calipers, Indicators and depth gages, which allow users to measure faster, more easily and more reliably. Measurement data is transferred to an i-Stick on a computer without any interfering data cables, and MarCom software makes data acquisition simple: just take a measurement and transmit measuring data directly into MS Excel or via a keyboard code into any Windows program or existing SPC application.

The company says it's the first digital micrometer with large 10 mm digits on a high contrast digital display, making for safe, fatigue-free reading of the measured values. It offers an easy to understand tolerance display and additionally displays warning limits.

The reference system in the Micromar 40 EWRi makes handling the micrometer very simple since the zero position is set only once. This setting remains stored for all further measurements. Also, a new "Hold" function (digital lock) allows measured values to be "frozen" so they can be easily read.

The micrometer is equipped with a state-of-the-art inductive measuring system that exceeds international standards, claims the company. Class IP65 protection against dust, coolants and lubricants makes the Micromar 40 EWRi ideally suited for use in difficult environments in the manufacturing environment.

The MarConnect integrated wireless interface is active as soon as the i-stick is plugged in, and each micrometer/caliper/indicator is identified by signal coding in the MarCom software so there is no confusion as to signals. The micrometer confirms whether the transmitted data was transferred correctly, or whether the operator is in the receiving area of the i-Stick receiver. Since the wireless data transmitters are built into the micrometer/caliper/indicator, no interface boxes or additional batteries are required. Plus, integrating the transmitters into the gage electronics makes the units extremely energy efficient and can extend battery life up to 50 per cent longer than competitive systems, according to Mahr.
