Latest Itemp Device Features Second Sensor Input

Endress and Hauser has introduced its new-generation Itemp temperature transmitters and components, which are designed to minimise risk in critical applications. Over the years, the company's Itemp portfolio has been continuously improved and developed, with increased functionality and housing options enabling the range to meet new industry requirements. Endress and Hauser's latest release - the Itemp TMT82 4-20mA HART temperature transmitter - features a second sensor input.

This can be used as a hot sensor back-up; if one sensor input fails, the device will automatically switch to the second. It can also be used to measure differential or average temperatures and drift detection between two elements. The HART signal opens up a range of additional diagnostic functionality over standard 4-20mA devices, including sensor-open or short-circuit alerts and sensor corrosion warnings. The new device will automatically send a signal to the control system to inform of the error, indicating a possible cause and suggesting remedies to overcome the issue.

For continuous measurement and diagnostics display plus additional service features, users can add the TID10 display. This plug-on display shows actual measured value as well as measurement point identification information. On attachment to the Itemp TMT82, it runs a start-up phase in which various device information and settings are shown in sequence, including sensor type, connection type and measurement range. This simplifies the identification of the measurement point during calibration and maintenance.

In the event of an alarm, an error message will appear on the display. When used with Endress and Hauser's range of display heads, the TMT82 temperature transmitter with TID10 process display instantly upgrades standard temperature assemblies for maximum data availability with minimum expenditure.

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.
