General Piezoelectric Theory | PCB Piezotronics
The resulting force on the crystals is easily calculated using Newton's Second Law of Motion: F=MA. Pressure and force sensors are nearly identical and rely on an external force to strain the crystals.

TN-26 Why Is MEMS the Preferred Technology for High Shock ... - PCB
accelerometers typically have mass motion from nanometers to microns. Previously, this small amo. nt of motion has precluded the achievement of any significant damping. In the past year, advanced MEMS processing technology has enabled.
Hermetic Connectors: Essential for Space-Bound Equipment
With its decades of experience and engineering expertise, Positronic understands how to design, develop, and manufacture the perfect hermetic connectors for testing space-bound technology. Why Hermetic Connectors?
What is a shock? - Temposonics
Sensors in industrial environments are usually exposed to shock and vibration loads. To ensure that the sensors can withstand such loads without damage, shock and vibration tests are carried out and values such as 150 g/11 ms and 30 g/10...2000 Hz are specified in the technical data.
HART-Enabled Vibration Transmitters - Wilcoxon Sensing Technologies
HART-enabled 4-20 mA vibration sensors make it easier and more convenient to analyze vibration data on your critical rotating equipment using existing HART networks as part of your process automation, condition monitoring and machinery diagnostics application.
Engineering Assets - All Sensors
Sensors for measuring pressure exceeding 15 psi have virtually no position sensitivity. Because the diaphragm of the sensor has mass, and because the mass to diaphragm thickness ratio increases as the pressure range decreases, the sensitivity to position increases as the pressure range decreases.
4-20 mA LPSTM series transducer selection guide
Wilcoxon’s loop powered sensors (LPSTM) are self-contained 4-20 mA vibration transmitters. LPSTM transducers can directly input a 4-20 mA signal to a plant’s control system and make the vibration condition of machines available to operating personnel. Machinery critical to the operation of the plant can be monitored continuously.

frequency is pictorially represented by a decreasing mass size from left to right. By convention, we assign to each oscillator a ratio of critical viscous damping of ξ = 0.03. Figure 4 provides enhanced definition of one of these oscillators.
P31 – MediaNugget - ssi-sensors.com
The P31 MediaNugget™ absolute & gauge pressure sensors are piezoresistive sensors without signal conditioning for low-cost OEM applications. The MediaNugget™ family of micro-machined, absolute pressure sensors has optimum media isolation for use with both harsh and benign media.

effects. If the acceleration-compensation mass is further adjusted, the sensor’s frequency response is also enhanced. This is called “frequency tailoring.”
Patrick L. Walter, Ph. D - PCB
It is possible to manufacture a placebo blast transducer, i.e., one that produces no piezoelectric output, using z-cut quartz. The placebo transducer can be applied in the test in the same manner as any of the operational transducers, but it will not respond to mechanical inputs (pressure, acceleration, strain).
