[New Product Preview] Six-Parameter Oil Quality Sensor: Improves Safety and Efficiency in Hydraulic and Fuel Systems
In industrial settings, the condition of oil directly determines equipment lifespan and operating costs. Traditional monitoring often requires multiple instruments—thermometers, viscometers, and densitometers—which not only takes up space but is also prone to misjudgments due to inconsistent synchronization. The ZH-600 six-parameter oil quality sensor, developed by ZHYQ, simultaneously measures six key parameters: temperature, dynamic viscosity, […]

Pressure Sensor Core Introduction
History of Piezoresistive Sensors: In 1954, C.S. Smith discovered the piezoresistive effect of silicon and germanium, which states that when an external force is applied to a semiconductor material, its resistance changes significantly. From the 1960s to the 1970s, silicon diffusion technology advanced rapidly. Technicians diffused strain resistors directly onto a silicon crystal surface, selecting […]
