6) Draw a circuit labeling all components for a device to measure temperature and convert the temperature to a 0 to 10 VDC single for a 0 to 500 °C input using the AD594.

7) The reason that the AD594/AD595 had an onboard thermocouple was?

8) Given an RTD at 0 degrees C has a resistance of 103 ohms what is it at 375 degrees C if it is made of Tungsten.

11) What types of industrial applications can an accelerometer be applied?

12) Draw a strain gauge circuit and its external components to attach to a conveyor mounted only at the ends to measure the load at the center of the conveyor. What type of testing would you need to do to establish a baseline and calibration curve for this sensor?

13) The circuit in question number 10 needs to be connected to a Labview network with both the input and output being tracked by Labview - select an interface to get this data into Labview (do not use the sensor daq) without the need for additional interface circuitry and justify your selection against cost, speed, and ability to have additional channels for other sensors. There are a tremendous number of manufacturers of DAQs, most interface to Labview.

14) What is an open collector input why is it used on some sensors.

15) List three types of vibration sensors and discuss how they operate.

16) What effect will temperature change have on a strain gauge mounted to steel and describe the multiple ways this can be compensated for by a user.
