Emerson Releases Fieldbus Digital Level Controller

Emerson Process Management's Fisher Fieldvue DLC3020f fieldbus digital level controller is able to deliver diagnostic information and alerts to help users improve performance while avoiding downtime. The DLC3020f uses displacement sensor technology for measuring liquid level or the level of interface between two liquids. It also employs the digital Foundation fieldbus communication protocol to deliver important information.

Digital communication makes it straightforward to configure, calibrate and test the DLC3020f using Emerson's AMS Suite software or the 475 Field Communicator as well as to integrate the instrument with new or existing control systems. Guided setup and calibration leads the user through the instrument setup, process fluid selection and calibration in an easy-to-use format, according to the company. The capability to select and define process fluids allows on-the-fly fluid changes for batch or continuous applications without calibration, saving time and recalibration costs. The instrument stores up to 30 logs including calibration, instrument setup and process fluid data that can be saved for future reference or reuse.

Advanced electronics provide increased performance and reliability, and process fluid temperature can be used when needed for density compensation to maintain process-variable accuracy. The DLC3020f is designed to directly replace pneumatic, analogue or HART transmitters/controllers. To provide additional flexibility, it can be mounted on a variety of Fisher 249 cage-less and caged level sensors, as well as on other displacer-type level sensors through the use of mounting adaptors.

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.
