The article deals with a piezoelectric force sensor, that bases on the use of piezo ceramics PZK 850. These types of sensors were used due to characteristic of the piezo-material (i.e. crystal) particularly for dynamic force measurement only. The developed sensor is suitable to measure static forces up to 50 N; the principle of the measurement of static forces bases on the crystal vibration being damped with the acting static force, whereby corresponding resonance frequencies are determined. The article describes the physical principle of the operation and the technical design of the sensor; there are presented two slightly different variations of the sensor. Further there are stated basic calculations of the sensor parameters and of the corresponding resonance frequencies. Finally, individual force-voltage characteristics are determined and respective results and possible use of such types of sensors are discussed.

本文介绍了一种基于压电陶瓷PZK 850的压电力传感器。由于压电材料（即晶体）的特性，特别是仅用于动态力测量，因此使用了这些类型的传感器。开发的传感器适合测量高达50 N的静力；静力的测量原理基于作用有静力的晶体振动被衰减，从而确定了相应的共振频率。本文介绍了传感器的物理原理和传感器的技术设计；提出了两种略有不同的传感器变化形式。此外，还陈述了传感器参数和相应谐振频率的基本计算。最后，
