Michell Supplies Chilled-Mirror Dew-Point Device

Michell Instruments has provided its Optidew Transportable chilled-mirror dew-point instrument for a manufacturer of desiccant dryers. The client needed the instrument to certify the functionality of its dehumidification systems. The Optidew Transportable combines the drift-free performance of the chilled-mirror principle with the convenience of a transportable instrument. Housed in a specially designed case, the instrument is fully self contained as well as being small and light.

For the client, having an instrument that was easily transportable was vital because of the range of situations where their dryers are installed. Desiccant de-humidifiers create dry air that can be used in a variety of applications such as in the leisure industry for swimming pools and sports halls, various utilities such as power stations and water treatment works, desiccant cooling for air-conditioning systems or within the chemical, food and pharmaceutical industries.

The Optidew Transportable allows engineers to check the reliability of their installations over time. The Optidew dew-point hygrometer works on the fundamental optical dew-point measurement principle, giving unmatched drift-free performance in the long term, according to the company. It offers a measurement range from the equivalent of less than 0.5 per cent up to 100 per cent relative humidity and measures dew points as dry as -40Cdp at ambient temperatures.

The portable version features a high-definition alphanumeric display that shows the measured humidity, dew point, water activity, grams per kilogram and a number of other hygrometric units. The whole hygrometer is self contained in a custom-built case for optimal protection and ease of use.

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.
