Piezoelectric Force Washers with New Nominal (Rated) Forces

The piezoelectric force washers in the CFW series produced by the measurement technology specialist HBM have proven themselves in numerous applications since their introduction.

The complete delivery with centering rings and plug protection characterize these sensors as much as the excellent linearity resulting from the symmetrical design.

In order to meet the demand for an expansion of the nominal (rated) force range, two new variants of the CFW type piezoelectric force washers are now available. They offer nominal (rated) forces of 100 kN and 190 kN, usefully rounding off the series range.

The new sensors evidence all advantages of the known force transducers and are also delivered complete with centering aid and cable protection. HBM has once again expanded their product range in the sector of piezoelectric force measurement technology.

The new sensors have an internal diameter of 13 mm (100 kN) and 21 mm (190 kN), and are therefore suitable for mounting on bolts and screws with the corresponding diameters.

In addition to the above-mentioned advantages, the new types are characterized by a very low displacement - like all members in the CFW type family - which results in high rigidity and a very high resonance frequency. This makes these sensors unusually suitable for highly dynamic measurement tasks.

When selecting the nominal (rated) force, only the necessary overload capacity and the geometric requirements must be taken into account, as all piezoelectric force washers output approximately the same output signal for any given force. All force washers are tested before delivery and are delivered with a test certificate.

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.
