The measurement of electrical properties is made by driving the sensor into oscillation with a crystal impedance meter, gain-phase analyzer, spectrum analyzer or similar device, and measuring the resultant parameters.
CrystalTech measures and records electrical data using Saunders Model 150D and Model 110HF Crystal Impedance Meters. With the 150D meter, resistive and capacitive loads and drive level are user selectable. We typically test sensors at 200 ohms, 30 pF, and 50 m watts, respectively.CrystalTech provides statistical summaries of 25 readings of fifth overtone oscillation at both 50 m watts and 20 m watts for each sensor. A summary of third overtone oscillation is also provided.
The following electrical parameters are included as typical values to aid in the design of oscillator circuits.Note:
| Total Capacitance between Tabs: | 2.50 pfd (typ) |
| Motional Capacitance of Crystal: | 0.10 ffd (typ) |
| Nominal Pressure Sensitivity: | 2.4 hertz per psi (typ) |
| Inductance: | 5.5 henry (typ) |
