Variohm Launches IP67-Rated Pressure Transducers

Variohm Eurosensor has introduced a CANopen-enabled series of pressure transducers for hydraulic, pneumatic, air-conditioning, environmental engineering, agriculture and automotive applications. According to the company, the new SMC series provides high-accuracy measurement up to 2,000bar in a compact and robust IP67-rated stainless steel design based on the 22mm hexagonal industry standard.

The CANopen protocol ensures straightforward, industry-standard commissioning with interfacing to CAN 2.0A or optionally CAN 2.0B, and the 1Mbit/sec data rate ensures fast update pressure measurement. The SMC series is available in more than 20 standard measurement ranges, with a selection of overload and burst pressure ratings that ensure maximum safety. With a media temperature range of -40C to +125C and temperature coefficient compensation between -20C and +85C, the overall measurement accuracy is within 0.05 per cent and repeatability is better than 0.1 per cent.

The fully welded stainless steel casing uses an encapsulated thin-film sensor technology that does not rely on a transmitting media and, as a 'dry' measuring cell, is suited to applications where leakage would be a problem. With a shock rating of 1,000G and vibration to 20G, the durable transducers can be used for gas and liquid pressure measurement for hydraulics and pneumatics applications as well as general industrial uses in air-conditioning, environmental engineering, agriculture, automotive and process control applications.

The SMC series is supplied in two- and three-wire connector versions for M12, M5 and integrated Y piece, with pressure connections available in G1/4 A and B, G1/2 B and 1/4 NPT. Accuracy ratings, pressure connections and connecting options can be customised on request.

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.
