Total Control with the Batch Controller RA33

The RA33 Batch Controller provides precise results and at the same time easy handling through

  • automatic correction of overrun quantity
    • Closing a mechanical valve needs time. The flow that takes place in the time between the Batch Controller closing command and the actual flow stop can significantly influence the accuracy of the filling. The Batch Controller records these quantities and corrects them with a time-shifted closing command. The measurement of the overrun quantity is done in the background at each further filling process and is then continuously corrected. Thus even continuous changes due to e.g. valve aging or deposits in the piping system are compensated.
  • volume correction
    • High cost products such as mineral oils require a compensation of external factors like pressure and temperature. These influence the volume of the mineral oil and thus affect the accuracy of the filling process. The correction is described in the standard ASTM D1250-04 and in API MPMS 11.1. Two possible calculation methods are available in the RA33 Batch Controller.

The RA33 Batch Controller enables:

  • Swift and at the same time accurate dosing by means of two-stage control
  • High-precision measurement with automatic correction of overrun quantity and temperature / density compensation
  • Quick and easy operation via function keys and numeric keypad
  • Complete control due to a flexible output control
  • Safety through hardware setup lock and lead-sealable housingCost benefit due to mass calculation from volume flow and temperature measurement

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.
