A capacitive level sensor has the dimensions and properties shown below .what is the capacitance c in picofarad.
H=4m
h=3.9m
a=1.0 mm(Millimetre)
b=6.0 mm(
E=8.8542*10 picofarad/ meter
K=78.5
Please explain ABB 266MRT, 266GRT and 266ART Pressure transmitters with seals (DP).how to calibrate as a level transmitter? And , is there a need of zero suppression in this model?
