Economical Testing of Manufactured Parts

High-quality plastic, sintered metal and die-cast parts must not exhibit any cavities, but should be fully molded and complete. A deviation of just 0.001% can make the difference between good and reject parts. WMS weighing modules detect such deviations quickly and reliably.

The high-resolution WMS weighing modules are designed for quick and high-precision filling and checkweighing during automated production. A repeatability of 0.1 mg in a weighing range of 400 g ensures that even the smallest weight deviations are detected. Such deviations can indicate shaping errors, insufficient coating, incorrect amounts of lubricant, incompleteness or the wrong density. The high long-term stability of the WMS weigh modules prevents that good parts from being are rejected because the drift error of the inspection equipment exceed the parts' tolerance limits.

The simple calibration of the weighing modules simplifies the checking of inspection, measuring and testing equipment in accordance with ISO 9001 or ISO/ TS 16949. A built-in calibration weight is available as an option, allowing the correct function of the equipment to be tested and documented at any time.

The WMS can be easily integrated into machines. Its robust stainless- steel housing and built-in overload protection allow robots to be used safely in automated production. The weighing pan is also easy to replace, which makes product changes quicker thanks due to the ability to switch weighing pans which are appropriate for specific parts. The degree of protection can be temporarily increased to IP66 for the purposes of cleaning.

It is also possible to connect the weighing module to a programmable logic controller (PLC). The following fieldbus modules are available for this: Profibus DP, Profinet IO, DeviceNet and Ethernet IP. Connection in the control cabinet is made efficient and simple thanks to a terminal module for the fitting of DIN rails.

Make the most of the reliability of a WMS weighing module and the expertise of our weighing specialists to achieve economical, 100% accurate testing of manufactured parts.

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.
