Mahr Linear 100 Now Faster and Easier to Use with New MarCheck Measuring and Evaluation Unit

Mahr Federal has introduced a new MarCheck measuring and evaluation unit for its high precision Linear 100 universal length measuring instrument. MarCheck allows both measurements and calibrations to be performed quickly and reliably at the touch of a button. Results are clearly shown in large digits on the display screen and can be output via USB or RS 232 ports. With a direct measuring range of up to 50 mm (2 in.) and an application range of up to 100 mm
(4 in.), the Mahr Federal Linear 100 provides rapid high-accuracy internal and external measurements directly on the shop floor.

"The MarCheck evaluation unit makes the Linear 100 even more versatile for precision measurement on the shop floor," said George Schuetz, Mahr Federal's Director of Precision Gages. "In addition to performing sub micron measurements, the Linear 100 with MarCheck now helps precision machinists save time by performing calibration checks, such as setting direct-reading measuring equipment or 2-point bore gages."

Key to the development of MarCheck was intuitive operation. Easy-to-use menus guide operators, and measurements are performed systematically using function keys. The Linear 100 with MarCheck offers a more economical alternative to rings and gage blocks for shop-floor mastering of inner and outer comparative measuring equipment, 2-point measuring instruments, inside calipers, and dial comparator snap gages. MarCheck upgrade packages are also available for older length measuring machines.
Compact in design, the Linear 100 features an adjustable 76 x 76 mm (3 x 3 in.) measuring table for precise adjustment of part position when measuring ODs, and a 4 to 40 oz (1 to 11 N) adjustable measuring force that remains virtually constant over the entire measuring range. For ID measurement, the 100 mm (4 in.) x 185 mm (7.3 in.) worktable allows for precision part positioning for measurement. The integrated measuring system is based on the Abbe principle (i.e., the measuring arm and reference are in line) which eliminates cosine errors.

Internal/External measurements, as well as Combined Internal/External measurements, are possible without remastering, and easily interchangeable measuring anvils provide increased part measuring versatility. The solid cast body reduces stresses and twisting error, and a large digital display provides clear readouts with selectable ID/OD results and preset values. An RS-232 interface makes it easy to transfer output data to PCs, and optional software allows measured values to be transferred to Windows programs such as Microsoft® Excel.

Mahr Federal Inc., a member of the Mahr Group, is known worldwide for its expertise in providing dimensional measurement solutions. The ISO 9001:2000-certified company is headquartered in Providence, RI, and manufactures and markets a wide variety of dimensional metrology products. Mahr Federal's calibration system is accredited to ISO 17025 NVLAP Lab Code 200605-0.

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.
