Pressure Differential Sensor

---

The PMD440 series is a small form factor pressure differential sensor. This series of products use high-reliability silicon piezoresistive differential pressure sensors as the core components, and output standard industrial signals after temperature compensation, digital circuit correction and signal conditioning. 

The PMD440 series is a small form factor pressure differential sensor. This series of products use high-reliability silicon piezoresistive differential pressure sensors as the core components, and output standard industrial signals after temperature compensation, digital circuit correction and signal conditioning. Each type of product has undergone processes such as careful design, component selection, process verification and curing, cyclic loading and aging, and environmental simulation testing to ensure that each product is stable and reliable.
PMD440 series differential pressure transmitter is widely used in various differential pressure measurement due to its excellent accuracy and reliability. Especially in coal mine, oil field, chemical industry, civil explosion, environmental protection, medicine, water affairs, shipping and other industries
