Construction machinery is an important component of the equipment industry, and with the development of technology, the application of sensors in mechanical engineering is becoming increasingly widespread. As a device capable of sensing and measuring environmental parameters, sensors can convert actual physical quantities into electrical signals, providing important data support for construction machinery. Our products have a complete usage plan in construction machinery, such as measuring and monitoring the main pump pressure and pilot pressure of the hydraulic system, measuring and monitoring the displacement of the hydraulic cylinder, and measuring and monitoring the liquid level of diesel and hydraulic oil.
