* 12/13/96 31 Intro-1 (= Transparency 19) We need to know temperature to compensate for its affect on the elasticity and rigidity of the metal flow tubes, which determine how the tubes responds specifically to flow and density. We’ll discuss that again later. The temperature indicated by the RTD also represents the temperature of the process with considerable accuracy. In current Micro Motion sensor design, the RTD temperature is equivalent to a thermowell sensor in terms of indicating process temperature. * 12/13/96 4 Intro-1 (= Transparency 2) Note: TX-2 depicts a system based on the RFT9739. For the same system with the RFT9712, use TX-144; for the IFT9701, use TX-145. Use TX-2 to orient the class: Point out corresponding components on the PMDs. Don’t spend a lot of time at this point explaining what particular components do or how to operate them. Also, don’t confuse things at this point by using model designations. Make sure class understands the distinction between the transmitter interface (used to communicate with the transmitter but generally not required for normal operation) and the peripheral interface (which is usually the operating interface with the flowmeter). * 12/13/96 4 Intro-1 (= Transparency 2) Note: TX-2 depicts a system based on the RFT9739.
