A newly hired chemical engineer at Hypothetical Industries is responsible for monitoring and maintaining temperatures for one of the company's exothermic reactions. The process uses a platinum resistor thermometer to measure the temperature of the process, the properties of which are given below. The reaction's ideal range is between 250°C - 350°C. Below 250°C, the catalyst ceases to function, and above 350 °C, it can be classified as a runaway reaction. The engineer can control steam and cooling water to regulate the process temperature.
Describe what changes the engineer should make to either the flow rate of the coolant or the steam to keep the system functioning optimally.
Case I: RT = 25ohms
Case II: RT = 13.9ohms
Case III: RT = 19.4ohms
An OpAMP has a GBWP of 100MHz and a slew rate of 10V/us and AVoc = 160dB at DC. Assume VCC = +/- 15 Volts. a. If the opamp is configured as a non inverting amplifier with voltage gain of 50.

An LVDT is used in an accelerometer to measure seismic-mass displacement. The LvDT and signal-conditioning output is 0.31 mV/mm with a +/-2 cm maximum core displacement.
A certain amplifier has an open circuit voltage gain of unity,and input resistance of 1 MΩ, and an output resistance of100Ω. The signal source has an internal voltage of 5 Vrms and an internal resistance of 100kΩ. The load resistance is 50Ω.
Devise a system that will convert this temperature range into an 8-bit digital word with conversion from 00H to 01H at 200°C and from FEH to FFH at 350°C . An ADC is available with a 2.500-V internal reference. At 200°C a type K TC produces 8.13 m..
