英国通用电气有限公司的试验室曾制成一种精巧的钛酸钡应变仪,这种应变仪已被认为在振动测量的场所中极为有用,这是第一种在这个国家里被广泛采用的应变仪,并较旧的检查和测量振动的方法有许多优点,这些应变仪价廉,可靠,使用简单,同时小巧的尺寸使得它们能在不可容纳较大试验装置的各种情况下应用。 In the laboratory of General Electric Co., Ltd., Britain, a delicate barium titanate strain gauge was made. This strain gauge has been considered to be extremely useful in the field of vibration measurement. This is the first widely used in this country. Strain gauges, and older methods for checking and measuring vibrations, have many advantages. These strain gauges are inexpensive, reliable, and easy to use. At the same time, their compact size allows them to be used in situations where larger test devices cannot be accommodated.
