SELF-ACTING PRESSURE CONTROLS
This tutorial examines various types of self-acting pressure controls, including direct-acting bellows-operated, diaphragm-operated and pilot-operated valves, and has guidelines on how to select and install them correctly. Pressure-reducing valves are considered together with pressure-maintaining valves and surplussing valves, along with some typical applications. The direct link is at bit.ly/1ixLr3d.

PRESSURE SIGNAL CONDITIONING
This basic tutorial explains such basic concepts as optimum feedback resistance, instrumentation, measurement, output, simple signal conditioning, error, circuit and calibration. In addition, it discusses ratio, excitation, sensor signal conditioning, pressure, feedback, amplifiers, excitation current and more. The PDF also contains links to a variety of other pressure-sensing tutorials. The direct link is at bit.ly/1mbSXAk.

SMART SENSOR CALIBRATION
This tutorial explains the common principles of calibration, re-ranging and trim as they apply to various kinds of transmitters. The principles apply to all kinds of smart sensors, but there is special emphasis on differential pressure transmitters. Subjects covered include sensor trim, range setting and current trim. The free PDF is available at bit.ly/TlFPx4.

PRESSURE SENSOR COMPENSATION
This technical paper discusses the implementation of a novel digital temperature compensation method developed for piezoresistive pressure sensors for the field of capacitive sensors. Possibilities for the compensation of sensor parameters such as sensor nonlinearity and temperature sensitivity are analyzed. Different approaches to digital descriptions of sensor characteristics, such as two-dimensional rational polynomial description and Chisholm approximants, are investigated and reported. Results of sensor response are compared against reference pressure sources, and the most effective digital temperature compensation is proposed. The direct link is at bit.ly/1uUwXKZ.
