Smart pressure transmitters,rent in a microprocessor to increase the accuracy and versatility of the transducer, while retaining the traditional output signal format of a 4–20 mA analogue current signal representing the total input pressure span. This retention of a standard signal output allows direct replacement of a traditi

PLIC

Measuring mass flow using the Coriolis principle,sensor. The paper is included as a good example of the way in which a description which could have been extremely mathematical and difficult to comprehend has been made accessible by a careful step-by-step approach to the underlying theory. (Eds.)

Silicon sensors meet integrated circuits,ted electronic circuitry for signal processing. The extremely small, relatively cheap sensors which can be made using these techniques have potential applications particularly in the field of medicine, where sensors implanted in the body can detect chemical and physical parameters for diagnosis and

泥土谦卑

Optical measurement methods,aper introduces the laser as a light source, and a range of light detectors. The technical detail of this first section is of interest, but a full understanding of the physical principles is not necessary for later sections of the paper. This paper deals with some of the ‘traditional’ optical sensin

正式演说

Measurement errors and instrument inaccuracies,is perfect; all introduce errors into the process of measurement. This paper discusses systematic and random errors, and introduces some of the mathematical concepts by means of which the likely effects of errors can be predicted.

How to calibrate flowmeters and velocity meters,er systems component inaccuracies. In some cases, where system components are subject to drift, or where extreme accuracy is required, a calibration procedure may be used many times a day. In other cases, where long-term stability of components is good, calibration may only occur once a week or once

HEAVY

Noise suppression and prevention in piezoelectric transducer systems, is specific to a piezoelectric accelerometer/charge amplifier combination, the description of sources of noise and how to reduce noise pick-up is applicable to a wide range of measurement situations using electrical transmission of the transducer output signal.
