Inertial Aerosystems Offers Tilt-Sensor Boards

Inertial Aerosystems has brought out a range of slim-line tilt-sensor boards, manufactured by US-based Applied Geomechanics. Designated the Tulip range, it consists of six models that are 4-20mA current-loop compatible with programmable controllers and similar factory-automation instrumentation. Tulip is current-loop powered and measurements can be made over long cable lengths using an economical two-wire pair.

These innovative products, weighing 15g, are designed to measure angular tilt where space and weight are at a premium. They can be mounted inside pressure housings, well-logging tools or on any machine or structure, and can be configured for vertical or horizontal mounting. Tulip comes in three angular ranges: a high-gain version of +/-10deg (20deg span) with a resolution of 0.005deg and 0.01deg repeatability; a standard version of +/-25deg (50deg span) with a resolution of 0.01deg and a 0.02deg repeatability; and a wide-angle version of +/-50deg (100deg span) with a resolution of 0.02deg and a less than 0.04deg repeatability.

The Tulip's electrolytic sensor has no moving parts, which means virtually no maintenance or calibration. The operating temperature range is -40C to +85C and the sensor has a built-in thermistor for temperature modelling. Each model comes with a calibration sheet showing variation with non linearity. Applications include well-logging tools, factory processing and control and structural monitoring.

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.
