Orbit3 System Networks All Industrial Sensor Types

Solartron Metrology's high-speed Orbit3 networking system is a fast and simple way to network industrial sensors of all types, including dimensional and position-measuring transducers. It builds on the Orbit2 system, offering substantial improvements and enhancements. Among the new enhancements are greater accuracy, which has been halved to 0.05 per cent of reading, and improved diagnostics, with local LED diagnosis displayed for each unit.

The sensors are now hot-swappable - an advantage where a large number of sensors are employed, such as in the manufacture of automotive windscreens. Up to 200 probes can be connected in a single network. Orbit3 is a means of building large, flexible sensors and gauging systems with a single common interface, regardless of sensor technology. Its high data-transfer rates provide dynamic and synchronisation capabilities for the measurement of moving parts.

In addition to Solartron digital transducers, the network allows a range of third-party sensors to be connected, including pressure, temperature and force transducers. At the heart of the network is Solartron's digital probe technology coupled with a robust RS485 multi-drop communications link. A system of nine-pin lockable connectors called T-Cons is used to channel the output of each input/output device on the network to the receiver electronics for analysis and display.

Each module has a unique identifier that simplifies data acquisition, especially in large multichannel networks. The new T-Cons are more robust, with a double latching mechanism and reduced weight, making them suitable for high vibration applications. They can be used individually, daisy-chained using computer cable or banked together in blocks to form a multichannel nest. DIN rail mounting is an option, as is IP65 environmental protection. Connection to PCs and PLCs is possible via an RS232 interface, with Ethernet communication models available shortly. Orbit3 is suitable for use in a range of industries, including automotive, aerospace and consumer electronics as well as test and instrument laboratories.

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.
