Ocean Optics Adds New Triggering Options to USB2000+ Spectrometer

Ocean Optics has added triggering functions to its popular USB2000+ miniature spectrometer to provide accurate timing and synchronization between the spectrometer and other devices. Four low-jitter trigger modes and normal (free-running spectral acquisition) operating modes are now possible. Applications include pulsing a light source to occur when acquiring a spectra and synchronizing spectral acquisition to coordinate with samples moving through a process stream or sensors reaching a certain temperature level.

Triggering provides precise timing between devices. The USB2000+ can be triggered so that sending the spectrometer a pulse causes it to do something such as a turn off or on a light, activate a pulse in a pulsed light source or start or end spectral acquisition in the spectrometer. For example, in the USB2000+ External Triggering mode, an event outside the sampling system (such as a button push, lever activation or laser) electronically pulses the spectrometer’s trigger pin and starts acquisition of the spectra with microsecond accuracy. The USB2000+ has an onboard programmable high-speed FPGA controller, 22-pin connector and 8 user-programmable digital I/Os. Available operating modes are Normal (spectrometer continuously acquires spectra) and the four trigger modes.

The USB2000+ is among the most popular miniature spectrometers in the world. Its small-footprint, high-speed CCD-array design is ideal for a wide range of applications. Modular optical bench accessories (entrance apertures, order sorting filters and more) make it possible to configure the USB2000+ for hundreds of different applications.

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.
