传感元器件是实现信息的检测、转换和传输的元器件,通过它可将各种非电的物理参量转换为电量,以它为核心可装配成多种有特定功能的传感器。它是仪器仪表的关键组成部分之一,人们常称之为仪器仪表的“眼”、“耳”、“鼻”、“舌”及“皮肤”。它们主要用在各种各样的仪器仪表和自动化装置中。 Sensing component is a component that can detect, convert and transmit information. Through it, it can convert all kinds of non-electric physical parameters into electric quantity. With it as the core, it can be assembled into many sensors with specific functions. It is one of the key components of instrumentation and is often referred to as the “eye”, “ear,” “nose,” “tongue,” and “skin” of instrumentation. They are mainly used in a wide range of instrumentation and automation devices.
