Accelerometers Are Shock Resistant To 2,000g

Inertial Aerosystems has announced a range of rugged, low-cost, triaxial analogue accelerometers manufactured by US-based Silicon Designs. The 2470 range consists of seven models that cover DC and dynamic accelerations from +/-2g to +/-200g full scale. The accelerometers use established MEMS technology and have a temperature range of -55C to 110C. They incorporate three orthogonal mounted accelerometers, with each axis independently powered.

The unit is enclosed in a rugged, lightweight, epoxy-sealed anodised case. Inside is a circuit assembly on a flexible board to help withstand shock and vibration. The devices feature low noise, 0.5 per cent linearity and a power range of 8V to 32V DC. These modules are tailored for zero to medium frequency applications, while onboard voltage regulation and an internal voltage reference eliminate the need for precision power supplies. The range is relatively insensitive to temperature changes and gradients.

The 2470 comes with a 1m eight-wire cable and is able to drive up to 15m of additional cable. These products are suitable for use in tough environments where space and weight are at a premium. They are shock resistant to 2,000g (0.1ms). Applications include crash testing, vibration monitoring and analysis, model analysis, robotics, flight testing, machine control and instrumentation.

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.
