Digital Calipers For Manufacturing Measurements

Mahr Federal is to exhibit a new generation of its line of Marcal digital calipers at IMTS 2010 for a range of measurement applications within the manufacturing environment. Included in the line are several features, such as lapped guide-ways, a reference system that retains the zero position setting, and an increased number of product options and accessories. Marcal digital calipers are available with protection against dust and immersion to class IP67, provide increased battery life, offer a range of data output options, and are available in a range of sizes, and blade and anvil configurations.

The new reference system available on Marcal R-designated digital calipers is designed to be a significant time-saver for operators. Unlike older models, which require the zero position to be reset whenever the calliper is switched on, the Marcal reference system retains the zero setting, so that the unit is ready to measure whenever it is turned on or the jaws are moved. A reference lock protects the setting from operator error and the reference system is claimed to be much more energy efficient, providing up to 50 per cent longer battery life.

Mahr Federal's stand will also display a new option package for the company's Marform MMQ 200 Formtester, which provides the measurement of surface finish parameters according to accepted ISO, ASME, and JIS standards. With the combined hardware/software MMQ 200 Surface Finish option, operators will benefit from reduced set-up and measurement cycle time, and reduced cost, by needing only a single piece of equipment for both form and surface measurements. The Marsurf UD 120, which can generate both surface and contour measurements in a single pass, will also be showcased.

Designed for economy, the system provides high accuracy over a large measuring range in nanometre resolutions. The Marsurf UD 120 includes both automated motorised operation and joy-stick control, along with a patented magnetic probe mounting feature that prevents probe damage and allows probe changes in seconds and without any additional tools. The Digimar 816 CL height gauge provides accurate measurements without complicated procedures, according to Mahr. Robust design and user-friendly operation combine with advanced features and functionality to improve dimensional measurement on the shop floor or in the lab.

The Precimar Linear 100 is a universal, user-friendly length-measuring instrument for rapid, precise internal and external measurements up to 100mm (4in), directly in the manufacturing environment. The unit includes the Marcheck Display, which makes it easy to transfer measured data to PCs. In addition, the 800 EW digital test indicator, which is shockproof, anti-magnetic, protected against coolants and lubricants to IP65, offers data output via USB or OPTO or RS 232C, and battery life of up to two years.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
