“…Measurements were performed with an angular resolution of 0.5 crankangle degrees and a Yokogawa DL708E oscillographic recorder was used. The pressure sensor was calibrated according to the usual method [22] based on a quasi-steady calibration by means of a deadweight tester with NPL and NIST traceability. With this procedure, the relative error obtained from the calibration of the transducer was ±0.7%.…”

“…Waves of the bulk acoustic type (BAWs) can be invoked Figure 41. Selected applications of piezoelectric transducers with respect to both the direct piezoelectric effect (active transducer) and the converse piezoelectric effect (passive transducer) [222] (with permission from Springer-Verlag, Heidelberg) Figure 42. Schematic overview of acoustic gravimetric devices, illustrating the principles of wave propagation and design [228] (with permission from VDE-Verlag, Berlin) a) BAW; B) SAW; C) APM; D) LW substrates for microgravimetric applications through the use of either AT-or BT-cut plates derived from a single crystal of a-quartz, where ''AT'' and ''BT'' refer to cuts with specific orientations relative to the main axis of the crystal (see below and [229]).…”

“…The temperature dependence of the relative frequency for various cuts of quartz crystal is shown as a function of the angle of cut in Figure 57 [262]. More detailed theoretical treatments of piezoelectric solids and their properties are provided by [222], [263][264][265]. Another more sophisticated approach based on dynamic quantum mechanics is presented in [266].…”

“…KING was the first to use a quartz microbalance ''QMB'' (in 1964) as a gas-phase detector in an analytical application [207], [208]. Numerous more recent papers discuss the fundamentals [209][210][211][212][213][214][215][216] and applicability [217][218][219][220] of bulk acoustic wave (BAW) piezoelectric resonators as chemical and biochemical sensors in the gas phase as well as in liquids, but physical devices for the measurement of pressure, temperature, or distance have attracted greater commercial interest [221], [222]. Nevertheless, quartz microbalances based on bulk acoustic waves do find frequent use in analytical research and development.…”

“…En efecto, en este caso, sería necesario desarrollar una herramienta especifica para simular las condiciones cambiantes de presión en cilindro, una tarea demasiado compleja y cara. Por tanto, se ha empleado un método tradicional [185] basado en la calibración cuasi estacionaria, mediante un equipo hidráulico de pesos muertos Hotek 9000 series.…”
