Trace Moisture Analyser for Specialty Gas Industry

The DF-745SG trace moisture analyser from Delta F brings the capabilities of the 700 series to applications requiring the accurate measurement of trace moisture levels in gas mixtures. The analyser is also suitable for applications within the specialty gas industry. Manufactured by Delta F, a division of Servomex, the DF-745SG is a process analyser optimised for measuring moisture in a specialty gas stream.

By utilising the latest tuneable diode laser absorption spectroscopy (TDL) technology, the DF-745SG delivers accurate moisture level readings with a performance enhanced by drift-free operation, low maintenance and low calibration advantages. This combination of high-sensitivity 100ppb low detection limit with a range of 0.1ppm-100ppm means that specialty gas plant owners and operators can utilise the DF-745SG to improve efficiency, increase plant throughput and improve yields. At the centre of the DF-745SG is application software specifically designed for blending specialty gases involving single gases and mixtures with up to eight components.

With a database of 13 standard background gases, the user can pre-define gas mixture templates for routine blends or define a custom mixture using the front control panel. Users can also add custom gases to the database using a simple data collection procedure. The DF-745SG stores detailed data that identifies the components and volumes in a mixture as well as the date, time and moisture content of the blend. This data can be displayed on the analyser's built-in data screen or downloaded via a USB drive as a Microsoft Excel spreadsheet report.

The DF-745SG is available in a 19in rack mount suitable for a fixed system and is light enough for cart or other mobile applications. The analyser can be quickly moved from port to port thanks to isolation hardware and software routines that virtually eliminate long dry down times often associated with these applications. The application firmware allows the user to easily configure the system to meet the particular needs of the plant using pre-defined blend templates.

The hardware design allows the user to start the unit up quickly and easily. The DF-745SG is suitable for a range of specialty gas production applications including monitoring specialty blends for quality control.

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.
