The New ODiSI, Enabling High Resolution Strain & Temperature Measurements

The new ODiSI (Optical Distributed Sensor Interrogator) from Luna Technologies builds upon their award winning fibre optic technology to provide a unique and dedicated distributed temperature & strain sensing platform.

Advantages:

    Easily deployed, inexpensive, disposable sensors
    1000’s of sensing points in a single fibre sensor with a single instrument
    Fibre is lightweight, requires no extra wiring, and is immune to EMI/RF interference
    Simultaneous strain and temperature measurement with a single fibre sensor
    Re-process sensor data at a later time with more/different sensing points

Fibre optic sensor technology is being utilised more widely as demands for lighter, stronger, and safer structures continue to increase. The ODiSI platform provides a sensing solution that is rich in data content, lightweight, robust, easy to install, and does not require expensive Fibre Bragg gratings. ODiSI gathers strain or temperature data along the entire surface under test and allows users to redefine sensing points in post processing; these features are not available with traditional static point sensors.

Specifications:

    Two versions, with 50metre or 10metre maximum sensing length
    5 mm spatial resolution
    +/- 1 microstrain and +/- 0.1 degC accuracy with 1cm gauge length
    +/-15,000 microstrain range with 50metre version
    +/-13,000 microstrain range with 10metre version

ODiSI provides distinct benefits to the aerospace, automotive, energy, civil engineering and general composites industries (to name a few) by giving greater insight into the design performance, tolerances and failure mechanisms of structures and vehicles.

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.
