LPD-N 4-20mA SIGNAL POWERED TRICOLOR LED BAR-METER Like analog meters, OTEK ’s Powerless ™ LPD-N is loop powered, meaning it only requires a loop to operate. Unlike analog meters, they have no moving parts to get stuck and are not sensitive to shock, vibration, magnetic fields, EMI/RFI or wear and tear. Unlike analog meters, OTEK ’s Powerless ™ units are HMI/MMI compliant with a configurable automatic tricolor bargraph, and are DCS/SCADA/intranet compatible. They can detect if there is a loop failure and... (read more)
Ground Detection Voltmeter to ground on either side of the battery causes the meter to move off center, indicating both the severity of the fault and which side it is on. The resistor value is selected so that a direct short to ground reads the full voltage. A digital bargraph meter will easily replace the analog meter in this circuit, often mounting in the same panel cutout. The bargraph meter provides both a digital readout and a highly visible bar to indicate a fault situation. To help spot a problem more quickly...

High Performance Alloys, Inc.
Bar Products High Performance Alloys stocks mainly round bar products. Their extensive inventory ranges in sizes from wire through as large as 12 Inch diameter. Normal stock lengths are 12 foot random (10 to 12, or 11 to 13) in length. Some bar products are carried in longer mill lengths of 10 to 18 foot randoms. Their inventory serves a dual purpose; they can sell it as a distributor product, or use it for manufacturing custom requirements in bar. High Performance Alloys is capable of manufacturing bar...

General Carbide Corporation
Boring Bar One of the most impressive material characteristics of cemented carbide is its stiffness compared to steel. This property is expressed in engineering terms as Modulus of Elasticity or Young's Modulus. All steel materials have a Young's Modulus value of 30,000,000 psi whereas cemented carbide has a value of 94,000,000 psi. Thus, carbide is 3 times more rigid or "stiffer" than steel. No other application takes better advantage of this distinguishing physical property than a boring bar application... (read more)Browse Boring Tools Datasheets for General Carbide Corporation
AT101-ZTX Bar-to-bar accessory The AT101-ZTX high-current surge test adaptor has been designed to successfully test DC motors, form coils and other low impedance windings with an AWAIV-6, AWAIV-12 or AWAIV-12HO tester. The lower impedance of series-wound armatures makes it difficult to surge test bar-to-bar. A higher surge test current is needed to produce the necessary bar-to-bar voltage differences. Standard surge testers can not produce the higher currents required to test low impedance windings. The AT101-ZTX high... (read more)Browse Hipot Testers Datasheets for SKF USA

Applied Image Inc.
Bar Code Standards APPLIED IMAGE Inc. in conjunction with UCC (now GS-1 US) and AIM, developed a unique set of bar code calibration standards, based on the ANSI X3.182, ANSI/UCC5, and ISO standards. In 1989, ANSI established a Bar Code Print Quality program creating a relative scale for bar code print quality levels which is now known as ANSI X3.182 (and also now ISO 15416) methodology. As an adjunct to the ANSI standard. Calibration of bar code standards is performed using a specialized, custom-built scanning... (read more)
