Abstract

The invention provides an impeller-type flowmeter flow high-speed sampling sensor to solve the problem that conventional sampling sensors are short in detecting distance, poor in diamagnetism and inaccurate in measuring. The impeller-type flowmeter flow high-speed sampling sensor mainly comprises a high-speed sampling probe and a sensor controller, a coil, a coil support and a protecting support are arranged in the high-speed sampling probe, and the sensor controller comprises a power-source power supply device, a radio wave generating device, a raid wave receiving device, a sampling recognition device, an edge steep pulse generating device, a sampling signal converting device and a sensor signal outputting device. The impeller-type flowmeter flow high-speed sampling sensor is suitable for various impeller-type flowmeters to realize high-speed measuring, and has the advantages of micro power consumption, wide voltage, good temperature characteristic and voltage resistance, excellent output signal and the like; in addition, the impeller-type flowmeter flow high-speed sampling sensor is free of any resistance on an impeller, long in detecting distance, good in resistance to ferromagnetism and accurate in measuring, and different shells can be chosen for different purposes.

Description

technical field [0001] The invention relates to a high-speed sampling sensor, in particular to an impeller-type flowmeter flow high-speed sampling sensor, which belongs to the field of sensor sampling. Background technique [0002] The impeller flowmeter is widely used as a device for measuring gas and liquid flow, and its key component is the measuring sensor. Most of the existing impeller flowmeters are assembled and debugged during production and manufacturing. The effective detection distance is small, the detection speed is low, the temperature drift is large, and the requirements for the application environment are high. Once damaged, maintenance and replacement need to be shut down. Trouble with maintenance. In addition, the existing impeller flowmeter itself has poor anti-pollution effect and poor anti-interference ability; additional protection devices are required for protection, which makes the production and inspection of the flowmeter difficult, and the probabi...
