RTD (Resistive Temperature Device) is a sensor that changes resistance with temperature in a linear relationship. RTDs are the most common temperature sensors used with rotary temperature transmitters. They may be specified as PT-100 indicating platinum-tungsten with a resistance of 100 at 0? C, PT-200, or PT-2000 and typically have a temperature coefficient of a = 0.00385.

Changes in temperature affect the elasticity of the metal flow tube, making it necessary to use an RTD for compensation to achieve the best possible flow and density accuracy. The RTD on Micro Motion sensors is also used to perform calculations for % concentration, standard volume conversion, and to provide a temperature output See similar questions...

Usually an electrical reference or excitation source is required for sensors whose electrical properties are measured. A thermocouple produces a potential difference between the two dissimilar metals that varies with temperature and is repeatable. The measurement is therefore a voltage. The resistance of an RTD changes with temperature, therefore, a constant DC current excitation source is used as a reference to produce a proportionally changing voltage. See similar questions...

Yes. This has been available since 23rd October 2006. You will need to purchase a wax tachograph disc scanner (available here from the Truck Trader RTD online shop) to digitally read the analogue wax disc. Having made this investment you will then have a single digital system to extract, store, analyse and report on your tachograph data. Remember that from May 06 your driver has been, by law, required to carry 15 days worth of tachograph data with him in the cab. See similar questions...

Each time you start Truck Trader RTD the software automatically checks to see whether there is a newer version available. If there is a newer version you will be asked whether you want to download it or continue with the version you have. See similar questions...

Yes. Support is available on 09074 021402 (50p/min) between the hours of 0800 and 1830 Monday to Friday. Yes. Digital analysis systems only read Driver's cards, they never delete any of the activities recorded to it. If you have any questions or queries with the Tachomaster System you may find the answer either in the FAQs on the web site, in the Tachomaster Software Help or Site Help. See similar questions...

Yes. The 658T is a 2-channel instrument. Both channels have dipswitches to select the type of RTD sensor and 10 ohm Cu is an option. Further, you can calibrate the channels within the range of the sensor type selected. First, the Intellipack 801T, 811T and 851T Transmitters offer a linearizer function in the transmitter configuration page of the Acromag Intellipack software package. See similar questions...
