Sierra Introduces Smart-Trak 50 Flow Controller

Sierra Instruments has announced the release of its Smart-Trak 50 Series flow controller for machine builders, systems integrators and end users. Sharing the same advanced core sensor technology as the Sierra Smart-Trak 100, the Smart-Trak 50 is now available at almost half the price with off-the-shelf delivery at no extra charge.

'The Smart-Trak 50 is a modular design, so users can add communications, displays or future functionality as required,' said Matthew J Olin, president of Sierra Instruments. This performance/price ratio was made possible by reducing the number of mass flow controller parts by almost 50 per cent, automating calibration around slightly reduced accuracy and leveraging research and development costs against already developed sensor, valve and LFE technology. Sierra has also streamlined delivery by stocking the seven most common flow ranges. OEMs that purchase in volume can achieve greater price reductions.

The Smart-Trak 50 is claimed to deliver an accuracy of +/-1.5 per cent FS, repeatability of +/- 0.25 per cent FS, 300ms response time and 0-50slpm (nlpm) range in a compact footprint. It comes with 316L SS wetted materials, field zero and span adjust, plus analogue outputs, RS-232 and RS-485, with optional large local display. Two DB9 connectors are located on either side of the enclosure for convenient wiring and the unit can be calibrated onsite.

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.
