Practice every matching question in batches of 20, with every available option.
An operator was told to control the temperature of a reactor at 60 °C. The operator set the set-point of the temperature controller at 60. The scale actually indicated 0 to 100% of a temperature range of 0 to 200 °C. This caused a runaway reaction by over-pressurizing the vessel, which resulted in injury to the operator. The actual set-point temperature was
Flow measuring instruments with different specifications (zero and span) are available for an application that requires flow rate measurements in the range of 300 litres/h to 400 litres/h. The appropriate instrument for this application is the ONE whose specifications are

The range of standard current signal in process instruments is 4 to 20 mA. Which ONE of the following is the reason for choosing the minimum signal as 4 mA instead of 0 mA?
A thermocouple having a linear relationship between 0 °C and 350 °C shows an emf of zero and 30.5 mV, respectively at these two temperatures. If the cold junction temperature is shifted from 0 °C to 30 °C, then the emf correction (in mV) is
