1. Introduction oil pressure sensor
pressure sensor, a piezoresistive effect by the pressure signal into an electrical signal. Oil pressure sensor is the industry’s most commonly used sensors, which are widely used in various industrial automation environment, involving water conservancy and hydropower, construction machinery, aerospace, transportation, petrochemicals, machine tools, pipes and many other industries. As an important part of the hydraulic equipment, a pressure sensor for pressure measurement and control, he can treat the sensed pressure and timely accurate measurement test result is transmitted to the subsequent display or control.
