|how to calibrate the radar transmitter for measuring the
exact tank level if tank is having agitator moving

|If an Instrument has 550 ohm internal resistance and the
cable used for that instrument is 0.5 ohm per meter
resistance. If the voltage is 12volt.How much length cable
can be used?
|A temperature sensor (RTD) connected via a temperature transmitter is adjusted to give an output of 4ma at 60 deg and 20 ma at 600 deg.
This output (4-20ma) from the transmitter is connected to an IGBT-inverter to control a high speed (-12,000 to +12,000 RPM) DC motor.
And in the inverter it is programmed as, for 4ma the motor speed will be -3,000 RPM and for 20ma the motor speed will be +10,000 RPM.
The question is : If the motor speed is +5,500 (RPM), what will be the temperature?
(-sign indicates that the motion is in reverse direction).
