It has been found that Angstrom Incorporated's thermal control system has failed due to a mercury-filled bulb sensor failure. Modern regulations prohibit mercury sensors from being used in thermal control systems, so you must research and convince management to select a suitable electronic thermal sensing element from the many available today. You must be able to maintain, calibrate, and set up the sensing system that will be replaced when it is necessary for replacement. Ensure that the sensing system is accurate over a temperature range of 50 C to 200 C. Present a comparison of NTC and PTC sensors. Are they sufficient to meet the requirements of Angstrom or do they require a different thermal control system?
