MRandP Extends Operating Life Of Sight Gauges

Minnesota Rubber and Plastic has converted a complex, three-piece assembly into a single-moulded part of high-performance plastic to increase operating life and lower costs of a radiator sight gauge. Custom moulded by Minnesota Rubber and Plastic (MRandP), these new sight gauges have operating advantages over the previous design. On the radiator, the sight gauges show coolant level without having to uncap and check the level or use a dipstick.

With a threaded base, the single component gauge locks tightly into position and is less prone to leakage. With good mechanical properties, the gauge has high heat resistance to 356F and material stability ensuring operating life up to 20 years. This precision moulding of high-performance Polyetherimide (PEI) by MRandP has improved design function and cost efficiency. PEI sight gauges and similar components are said to have excellent hydrolytic and UV stability as well as radiation resistance.

PEI is extremely well suited for repeated hot air, steam and cold chemical exposure. It is flame retardant and can be used for long periods at continuous temperatures up to 356F. This sight gauge design conversion, from a three-piece assembly into a single-moulded part, is a typical example of MRandP's design services. These are offered to further advance customer design and manufacturing programs.

The MRandP design services include: preliminary engineering assistance and mechanical design review, and materials engineering including research and development into a full range of high-performance plastics. MRandP also provides rapid mould design and development, FEA analysis, prototype services, process engineering, injection, compression transfer and liquid silicone rubber moulding including metal-to-plastic conversions.

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.
