The summary obtained from measurement transducers pressure gauge diaphragm type. It found that labor is a high resolution measurement up to the third decimal position. Make the values that pass the error to find the average value are different, at least until there is no difference at all and have found that the point at which there is no calibration error Loei. By the percentage error occurs, there may be a result of the chemical properties of the material. The loss of signal power and resistance stiffness of the device.Keyword.
