Wireless Digital Gauge “μMATE+”.
～ Improve manual measurements with digital measuring instruments that increase work efficiency
October 25, 2022
Magnescale Corporation (hereafter referred to as “Magnescale”) has released a manual digital measuring instrument, μMATE+, which will be exhibited at JIMTOF2022, held at Tokyo Big Sight from November 8 to 13, 2022.
Many dial and “lever type” indicators, are used in the assembly, processing, and inspection of manufactured parts, but most of them are still analog, and are used to visually read and record values on an analog dial, or to make a No/NoGo judgment within a tolerance. On the other hand, many facilities are considering transitioning from analog to digital data to save labor and improve efficiency, but the transitioning to digital dial indicators requires design and construction of the entire system, which is a high hurdle to achieve. We have listened carefully to the problems in the field and released a wireless digital gauge that is highly accurate, easy to measure, and makes the transition to digital data easy.
(1) As lightweight and compact as analog gauges (lever gauge: approx. 75 g)
(2) Easy-to-read and easy-to-operate 2.7-inch color LCD touch panel
(3) Supports wireless smartphone operation, data storage and processing
(4) Two new technologies that enable high-speed, high-accuracy measurement (patent pending)
Choose from two types of digital indicator gauges and digital lever gauges. While used for the same applications as analog versions, these products add the advantages of digital data collection. The main unit can wirelessly transmit measurement values to tablets and smartphones via Bluetooth communication. Free iOS and Android apps are available to control the unit and acquire data. (Fig. 1) Data can also be transferred from the main unit via USB or microSD card.
Development of new technology
We have developed two new technologies to achieve high accuracy and high resolution. (Patent pending)
(1) AL link mechanism (Arc-to-Linear mechanism)
Many dial indicators use linear motion or lever motion that converts gear rotation to move the dial indicator. Using gears causes backlash, which results in measurement error. Magnescale has developed an “Arc-to-Linear” mechanism that precisely converts the circular motion of the tip of the gauge into linear motion, thereby detecting position without backlash (Fig. 2). This mechanism achieves repeatability of 0.5 μm or less.
(Fig. 2) AL link mechanism
(2) ID sensor (Inductance to Digital conversion sensor)
A newly developed ID sensor is used to detect the amount of movement. The sensor has a compact and simple structure as shown in Fig. 3, and detects the change in inductance according to the amount of movement as an absolute value.
(Figure 3) ID sensor
Large, easy-to-read display and a variety of measurement views
A large, easy-to-read 2.7-inch LCD display panel is used, and five display modes are available to match the conditions of the object to be measured. (Fig. 4) In the display mode that mimics the movement of an analog needle, the familiar “runout” sensation of conventional dial gauges and lever gauges is used. Even in case like there, the digital value is saved, so it is possible to record it as a numerical value. In addition, you can select the most suitable display for your measurement purpose, such as bar meter, real-time chart, circle measurement mode, etc.
(Figure 4) Five display modes
Orders will be accepted from January 2023, and shipments will begin in April 2023. The sales target for the first year is 5,000 units per year, with sales of 50,000 units per year expected in a few years. The price is planned to be around 100,000 yen per set.
