PRISMA Instruments & Gauge .Bourdon France In continuation with its endeavour to provide products of best quality to clients, we have developed RTD with Nickel conductor in Mineral Insulated Construction for the first time in India. The basic difference between the conventional & Nickel conductor is material of conductor. In conventional, it is inst Nickel in newly developed MI. 1. Most important advantage is that the RTD element is welded on to conductors and not brazed. As such same RTD can be used for much higher temperature of up to 6000C . In conventional RTD with copper conductor, brazing...

RTD temperature transmitters convert the RTD resistance measurement to a current signal, eliminating the problems inherent in RTD signal transmission via lead resistance. Errors in RTD circuits (especially two and three wire RTDs) are often caused by the added resistance of the lead wire between the sensor and the instrument. Transmitter input, specifications, user interfaces, features, sensor connections, and environment are all important parameters to consider when searching for RTD temperature transmitters. Trans mitter input specifications to take into consideration when selecting RTD temperature...
