Non-Contact Linear Position Sensor is Robust

Variohm Eurosensor's new linear position transducers feature a novel non-contacting and long-life inductive measurement principle, for travel display or position feedback in industrial environments. The Novopad LS1 series, from Variohm's German distribution partner Novotechnik, features an integrated signal processor with optional voltage or current output. It also includes a teach function, which uses push buttons and a status LED to facilitate straightforward in-situ range setting.

The Novopad principle is based on a low-cost printed circuit board design that allows an absolute linearity of up to 0.05 per cent across the full measurement range. The push-rod style LS1 has a durable anodised aluminium housing with a profile of 18 x 18mm. With a double bearing support that allows high lateral forces at the rod tip, the transducer can be supplied with or without an internal return spring. The internal spring version, available in four measurement ranges from 25 to 100mm, includes a rear end adjustable stop nut to facilitate connection to hydraulic and pneumatic actuators or solenoids.

The non-sprung version, supplied in six range versions from 25 to 200mm, has a hardened ball coupling that enables backlash-free and shear force-free operation even with axis misalignment. Further options across both LS1 styles include a choice of 12- or 13-bit resolution to suit measurement speed and resolution requirements, as well as a choice of 0-10VDC or 4-20mA output to suit the direction of measurement. Electrical connection includes a three-wire free cable, a directly mounted three-way connector in both straight or angled M8 styles, or a cabled connector in a choice of cable lengths.

The non-contacting and wear-free transducer is capable of 100 million movements or 175,000 hours operation, with a maximum speed of 5m/sec and acceleration to 5g. Other environmental specification notables are a shock rating to 100g, vibration to 20g at 10 to 2,000Hz, and operational temperature range from -30 to +100C for the cabled version. Because the Novopad inductive measurement principle used in the LS1 is not affected by magnetic fields, they may be used in close proximity to magnetic devices, such as linear and rotary servomotors.

The transducers may also be exchanged or removed and replaced without the need for recalibration. The Novopad LS1 series is part of a wide range of Novotechnik contacting and non-contacting linear and angular position sensors available exclusively in the UK and Ireland from Variohm Eurosensor.

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.
