Gasmet DX4030 Simultaneously Monitors 50 Gases

Quantitech's Gasmet DX4030 portable FTIR gas analyser has improved the testing of cargo containers at ports and airports. The DX4030 can simultaneously monitor 50 different gases, including fumigants (both organic and inorganic), specific volatile organic compounds (VOCs), toxic industrial chemicals (TICs) and chemical warfare agents (CWAs). In addition to the instantaneous display of target gases, the FTIR records a sample spectrum from which hundreds of compounds can be analysed.

Cargo containers, wooden packing materials and foodstuffs are fumigated by shipping companies to control the spread of pests and micro-organisms. Fumigant gases are toxic and containers are therefore monitored for health and safety purposes on arrival at each new port or destination. In addition, products shipped in containers can release VOCs from solvents and glues used in the manufacturing process, and their concentration may accumulate in the confined space of a container.

FTIR offers major advantages over traditional portable monitoring technologies because of its specificity and lower susceptibility to interference gases. The FTIR analyser is found in a backpack and provides laboratory-grade analysis in a field instrument. A video demonstration of the DX4030 is available online at the Quantitech website and visitors to 'Counter Terror 2010' at Olympia, London on 14-15 April can view the DX4030 in action.

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.
