Transducer Fits Oil And Gas Exploration Tasks

The model PT36XX subsea wellbore pressure and temperature transducer from Stellar Technology is said to be ideal for use in harsh subsea oil and gas exploration environments. It has a total error band of +/- 1 per cent of full-scale output and is designed for working pressures to 15,000lb/in2 and seawater depths to 17,000ft. Both temperature and pressure sensors are located at the flush-end of the wellbore probe, a design feature that Stellar Technology said improves dynamic response and alleviates clogging.

This wellbore sensor includes dual pressure containment rated to 20,000lb/in2 for increased reliability. In addition, the PT36XX is constructed with no external load-bearing welds, therefore increasing service life and improving field serviceability. The PT36XX is constructed of Inconel and 316 stainless steel. It can be configured as a pressure-only or temperature-only unit. The standard unit incorporates a 3 1/16in API flange, although customers can specify their flange of choice.

Probe lengths are available in lengths of 3in to 24in. Both probe lengths and electrical terminations are customer-specified. PT36XX is also available with dual redundant pressure sensors for particularly demanding applications. Customers can select from numerous available electrical outputs - 4-20mA, 0-5VDC, 0-10VDC - as well as digital outputs including RS232, RS485 and CANbus. Each wellbore transducer is shipped with a multi-point calibration record, traceable to NIST as standard. Material traceability is also available on request.

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.
