Portable Refractometer Measures Dissolved Solids

At the National Restaurant Show (NRA) 2011, ITT Analytics introduced the Bellingham and Stanley Opti handheld refractometer, for Brix analysis of beverages and foodstuffs. Designed for use in food and beverage retail outlets, the Opti handheld refractometer is a portable device suitable for measuring dissolved solids. The device may be used to control the blend ratio and sugar or fructose content of post-mix beverages at point of dispense. This enables retail and restaurant outlets to ensure product quality and high product yield, so that costs can be controlled.

Measurements are completed in two seconds and only a small drop of sample is needed to provide a result. The Bellingham and Stanley ABV (Alcohol by Volume) test kit was also displayed at NRA 2011. This test kit enables the alcohol content of beer, wine or cider to be calculated from the combined readings of two portable instruments: the dual-scale Opti Wine (ABV) refractometer and a standard hydrometer measuring specific gravity.

According to ITT, the kit requires a minimal amount of sample to be used and provides a fast and accurate reading to 0.5 per cent ABV. Used in micro-breweries and beverage retail outlets, it allows owners to randomly determine the level of alcohol in mixed drinks being served. The second scale on the Opti refractometer is designed for use in breweries, to measure the initial soluble solids of Wort (degPlato) before the addition of yeast prior to fermentation.

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.
