Ginetta G50 Race Cars Use Variohm Pressure Sensors

Leeds-based Ginetta Cars has chosen Variohm EPT3100 pressure transducers to monitor oil, fuel and water pressure across all of its G50 series of race cars. The 300bhp G50 'Cup' race car is exclusively used for the single-make Michelin G50 Championship, which starts again in April 2010. A newly introduced G50Z version features a 400bhp Ford Zytek engine and is aimed at top-level GT sprint and 24-hour racing.

The latest derivative, the G50HC (hot climate), is built for the Middle East race-car market and is designed for track temperatures up to +60C. Throughout the G50 series, the engine control unit and data logging systems are used to ensure optimum performance and Variohm's EPT3100 series pressure transducers are built for challenging applications where high performance and reliability need to be balanced with lightweight design, compact dimensions and a competitive cost.

The EPT3100's thin-film measuring cell and high-level-output circuit technology provide a pressure output from 0.25bar to 4,000bar in several range options, with accuracy better than +/-0.8 per cent and stability more than +/-0.1 per cent. Output options include 0-5V, ratiometric and 4-20mA with up to 32V input. For maximum durability, the EPT3100 features a 1,000g shock rating and a 25g peak vibration rating at 20-2,000Hz. The IP66-rated sealed sensor is housed in a hermetically welded 304 stainless-steel casing, weighing 60g and measuring 22mm in diameter and 54mm in length.

A choice of miniature or standard DIN43650 connectors, or flying leads, is designed to make installation and field replacement straightforward. To meet the demands of the gruelling conditions for all types of autosports - and the most challenging industrial applications - the EPT3100 has an over-range pressure rating of 2x and a burst pressure capability to 5x, with a rated life of more than 10 million pressure cycles. The EPT3100 is a part of a range of specialist sensors and transducers that Variohm Eurosensor supplies across the autosports industry, including Formula 1, A1GP, WTCC, GP2, Champ, Nascar, ALMS and Superbike.

The complete range includes pressure and temperature sensor solutions for fuel, oil, coolant and brakes as well as force, torque and position measurement sensors for suspension travel, throttle and gearbox. Laser and infrared technologies are also supplied for ride height position and tyre condition.

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.
