Rosemount Inc. is a subsidiary of Emerson Electric Company. Its headquarters is located in Shakopee, Minnesota , where they manufacture measurement instrumentation such as pressure, temperature, level, DP flow, and wireless, as well as analytical and detection instrumentation for gas analysis, liquid analysis, combustion measurement and flame ...
By far the most common devices used in industry have a nominal resistance of 100 ohms at 0 °C and are called Pt100 sensors ("Pt" is the symbol for platinum, "100" for the resistance in ohms at 0 °C). It is also possible to get Pt1000 sensors, where 1000 is for the resistance in ohms at 0 °C.
The Callendar–Van Dusen equation is an equation that describes the relationship between resistance (R) and temperature (T) of platinum resistance thermometers (RTD).. As commonly used for commercial applications of RTD thermometers, the relationship between resistance and temperature is given by the following equations.
The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems.
[5] [4] Temperature control is used to maintain the desired temperature of the first fluid. A temperature sensor transmitter (TT) is located in the first fluid at its outlet from the heat exchanger. This measured temperature is fed to the temperature controller (TIC) where it is compared to the desired set point temperature.
PT100 or PT-100 may refer to: A type of the Taurus PT92 pistol; A type of resistance thermometer; Panzerfaust, a German anti-tank weapon of World War II
PICkit 2. The PICkit 2 was introduced in May 2005 [2] to replace the PICkit 1. The PICkit 2 has a separate programmer/debugger unit which plugs into the board carrying the chip to be programmed, whereas the PICkit 1 is a single unit.
The MITS 816 calculator kit used the chipset and was featured on the November 1971 cover of Popular Electronics. This calculator kit sold for $175, or $275 assembled. [11] Forrest Mims wrote the assembly manual for this kit and many others over the next several years. As payment for each manual he often accepted a copy of the kit.
