High-speed data acquisition T070B
The T070B four-channel distributed strain acquisition card is an Ethernet-based dynamic strain acquisition device with four 24-bit resolution synchronous measurement channels and a sampling rate of up to 30kS/s per channel.
Product Description
The T070B four-channel distributed strain acquisition card is an Ethernet-based dynamic strain acquisition device with four 24-bit resolution synchronous measurement channels and a sampling rate of up to 30kS/s per channel. It supports network topology to expand the number of acquisition channels and can meet the needs of high-precision dynamic measurement, such as dynamic weighing, strain analysis, dynamic force measurement and distributed state monitoring.
Summary
Sensors based on the strain principle are widely used in industry, scientific research, military and other fields. With the increasing degree of industrial automation, the real-time response of automatic control is stronger, and edge computing requires more data. The requirements for testing are further upgraded from qualitative testing to quantitative testing. In the fields of new energy, automobile assembly manufacturing, industrial robots, intelligent transportation, civil engineering and the Internet of Things, traditional static or low-speed acquisition is difficult to match the needs of dynamic measurement. The T070B four-channel distributed strain acquisition card expands the traditional force measurement response frequency from 100Hz to 10kHz on the basis of providing measurement accuracy.
