Lasense Piezoelectric Vibration Speed ​​Sensor

piezoelectric vibration speed sensor is composed of a piezoelectric sensor with a built-in micro amplifier and a precision integrating circuit. When the traditional magnetoelectric vibration sensor vibrates with the measured object, relative motion occurs between the coil and the permanent magnet, thereby generating a voltage signal in the coil that is proportional to the vibration speed, so the vibration speed can be measured. The ULT22 series uses piezoelectric crystals as sensitive elements. There are no relatively moving parts inside the sensor, which will not cause wear and aging. Therefore, it has a longer working life and better stability and reliability. ULT22 piezoelectric speed sensor is suitable for vibration monitoring, fault diagnosis, vibration analysis of bearings, grinders, machine tools and other mechanical equipment. It is widely used in electric power, metallurgy, machine tools, chemical industry, automobile manufacturing and other industries, gradually replacing traditional magnetoelectric vibration. speed sensor. This product has small mass, small size, easy installation, and can be installed vertically, horizontally or at any angle; it has wide frequency response, good linearity, and excellent dynamic characteristics; it has a long working life, reliable operation, and long-term reliable operation.

Merchant qualification:

Lasense Technology is a laser gas sensing company. Based on many years of original technology accumulation in the field of laser sensing by returnee R&D teams from the Chinese University of Hong Kong, Stanford University, and the Hong Kong Polytechnic University, it independently develops and produces ultra-high-speed gas sensors in Qianhai, Shenzhen and Hong Kong, China. Highly sensitive gas sensing instruments and IoT online monitoring systems. The team focuses on the precise measurement of carbon-containing gas elements and real-time monitoring of greenhouse gas pollution sources, using world-leading new spectroscopy technology to fill the market gap for such high-end domestic instruments. Since its establishment in November 2020, the Lasense Technology Project has continuously completed angel round financing with Inno Angel Fund and completed angel + round financing with China prosperity capital. In the national strategy of "carbon peaking and carbon neutrality", Lasense assumes the task of accurate and quantitative measurement of gas concentration, uses independent patents to solve the gas data needs of government monitoring and corporate customers' carbon trading, and builds it in the "double carbon" era. A new benchmark for domestic precision instruments.
