Spectral Shaping Available For OEM Applications

Ocean Optics has developed a light-shaping technique for its spectrometers that balances and smoothes the uneven spectral emission from UV-Vis light sources used for spectroscopy applications. The company said that as a result, users can measure light more evenly across a broader spectral region and therefore improve signal-to-noise performance. The technique is said to be especially useful for spectral absorbance applications where strong absorbing bands co-exist with bands of low signal in the unbalanced spectrum.

This low signal level limits the maximum measureable optical density. Traditionally, the spiky spectral output of a lamp - in other words, distinguished by sharp and narrow peaks - of light sources used in spectroscopy is handled at the source itself. But methods such as moving mechanical fixtures or optical filters at the light source can result in greater light loss and may be too expensive or impractical, especially when instrument-to-instrument uniformity is desired. The proprietary Ocean Optics spectral shaping technique modifies the light internal to the spectrometer so that specific wavelengths or wavelength bands are selectively attenuated. This makes it easier to optimise the spectrometer setup in concert with the light source.

The Ocean Optics OEM engineering team is now able to apply this novel spectral shaping technique to a variety of OEM applications. This dedicated engineering group provides expert support to help OEM customers being products to market faster and better optimised to commercial requirements. The team offers complete system design capability for OEMs from supply of fibre assemblies and light sources to sensor coatings and sample holders. The company is ISO 9001:2008 certified and can support both integrated system and sub-system manufacturing needs.

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.
