12.a. What is the purpose of thermostat number 2, IN7, in the mixing vat machine?A. This thermostat is used to monitor the temperature of the incoming fluids.B. This thermostat is used to prevent an over-temperature condition in the event thermostat one sticks open.C. This thermostat is used to turn off the mixing motor after the mixture reaches temperature.D. This thermostat is used to shut off the heater when the chemical mix reaches setpoint.12.b. Why are motor current readings from a frequency inverter not exact readings of motor current?A. Because the output of a frequency inverter is not a sinewaveB. Because a frequency inverter adds a DC voltage level to the AC waveformC. Because a frequency inverter uses a lower voltage sinewaveD. Because the inverter pulses the motor with various sinewave frequencies
Why is a low-voltage thermostat normally more accuratethan a high-voltage thermostat?
LVDT can be used as the primary sensing element .
