 Sensitive elements in quartz temperature transmitters are temperature-sensitive quartz resonators and transducers pressure - Manometric quartz resonators.
Calibration characteristic resonators described polynomial of second or third degree (approximation error of no more than 0.05% and 0.02%, respectively). F (P) = f O + A 1 * P + A 2 * P 2 + A * P 3 3
To compensate for the temperature error of temperature and frequency response is described as a polynomial of second or third degree (see example in Fig. Below).
