Description

Technical Field

[0001] The utility model relates to the technical field of signal acquisition devices, in particular to a dual-sensor signal acquisition device. Background Art

[0002] A dual sensor is a sensor that can detect two parameters at the same time. Its principle is to use two sensing elements to measure two different physical quantities at the same time. Compared with traditional single-parameter sensors, dual sensors have the advantages of high sensitivity, high precision, and fast response time. They can be used in a variety of fields, such as gas sensing, biosensing, electrochemical sensing, etc. The working principle of a dual sensor is similar to that of a single-parameter sensor, but it uses two independent sensing elements. The sensing elements can be capacitors, resistors, micro-electromechanical systems (MEMS), etc., and their changes reflect the physical quantity being measured. Under the control of the signal processor, the output signals of the two sensing elements are calculated to obtain the final measurement result. Signal acquisition equipment is a medical research instrument used in the fields of biology, electronics and communication technology, and computer science and technology.

[0003] The existing dual-sensor signal acquisition device is not easy to disassemble and assemble, which is not convenient for subsequent maintenance and inspection. Secondly, when the device is fixed on the wall surface, it is mostly fixed with fastening screws. The fastening screws will become loose after long-term use, affecting the use and installation of the dual-sensor signal acquisition device.

[0004] Secondly, the external structure of the dual-sensor signal acquisition device has poor protection. Dust and particle adsorption and accumulation in the dual-sensor signal acquisition device will reduce its service life, which urgently needs to be developed. Utility Model Content
