Gauges and Instrumentation are the Backbone of Accuracy
In metalworking, precise measurements ensure your shop meets stringent regulatory standards, minimizes errors and cuts down on rework. The post Gauges and Instrumentation are the Backbone of Accuracy appeared first on Fabricating & Metalworking.
Gauges and instrumentation facilitate the production of accurate and consistent products for a diverse range of industries. Discover the latest products that detect deviations so your shop can take corrective action before problems escalate.
Digital Test Indicator Offers Larger Measuring Ranges
Mahr Inc. (Providence, RI), a leading provider of dimensional metrology solutions, has updated its MarTest 800 EWR digital test indicators. The new versions of the 800 EWR incorporate an enhanced measuring system that provides longer measuring ranges of up to ±0.035″/±0.9 mm and ±0.086″/±2.2 mm, allowing for better accuracy and versatility.
The MarTest 800 EWR combines the benefits of digital indicators, providing a longer measuring range with high resolution, enabling users to measure faster, more easily, and more reliably while minimizing errors. Combined with the ability to automatically sense measuring direction, rotate the bezel 360°, and overtravel protection features, the test indicator replaces numeral mechanical test indicators.
The operating unit is protected against coolants and lubricants, with a protection class of IP65. Its shockproof design and precision bearing supported lever contact offer maximum reliability in harsh environments. The full-surface glass display provides protection against liquids and dirt, which cannot penetrate the sealed housing.
Key features of the MarTest 800 EWR digital indicator include:
- Inductive measuring system with a battery life of approximately two years.
- Compliance with DIN/ISO standards (meets or exceeds).
- Four measuring modes: Min, Max, TIR, and Direct.
- Combined analog and digital display.
- 360° rotatable operating and display unit.
- Automatic matching to sensing direction.
- Satin chrome finished housing with three dovetail guideways.
- Shockproof, anti-magnetic, and overload protection.
Surface Roughness Measuring Instrument is Portable and Easy to Use
Mitutoyo America Corp. (Aurora, IL), a leading manufacturer of precision metrology instruments and solutions, offers the new Surface Roughness Tester SJ-220 Series to our vast line of Form Measuring Instruments, providing compatibility and versatility to meet the diverse needs of manufacturing sites.
The SJ-220 series of surface roughness measuring instruments offers excellent portability and easier use with touch screen functionality for more intuitive operability. It is equipped with a built-in battery that can be used approximately 1,000 times on a full charge, enabling operators to perform measurements in environments where power is not available.
Key Features and Benefits of the SJ-220 Surftest:
- Expanded Color Touch Screen: The SJ-220 features a larger 2.8-inch color touch screen for better visibility while maintaining a compact size to operate with one hand.
- New Interface: The SJ-220’s new user interface is more intuitive with easier operations such as changing the display screen and adjusting settings with your fingertip.
- Advanced Functions: The SJ-220 includes new functions such as being able to disable the touch screen for better security along with setting shortcuts using the HOME key for most-used functions.
- Increased Efficiency: The SJ-220 can now display results and set measurement conditions via wireless communication when used with the optional accessory U-WAVE-TIB.
Precise, Reliable and Repeatable Measurements
At EASTEC 2025, Sunnen Products Co. (St. Louis, MO) demonstrated its latest innovations regarding honing technology and precision measurement. For precision measurement, Sunnen presented the PGE-6000 Electronic Bore Gauging System. This sophisticated instrument combines accuracy and versatility, offering a menu-driven operator interface and compatibility with SPC software for fast and easy data collection. The PGE-6000 is equally at home on the shop floor or in a controlled laboratory environment, providing reliable and repeatable measurements for a wide range of bore sizes.
Sunnen also demonstrated its supplied air gauging technology. This includes the optional in-process air gauging system for SV machines, designed to enhance precision and efficiency. Sunnen also demonstrated its new benchtop PGA gauge. These innovations underscore Sunnen’s commitment to providing state-of-the-art solutions for precision machining and quality control.
