FAQ

Q1: What is the importance of a differential pressure sensor in a system? ❯

It provides accurate pressure change data, helping ensure efficient and safe system operation.

Q2: How is a differential pressure signal generated? ❯

When the pressures at the two ports differ, the diaphragm bends. This bending changes the sensor's capacitance, resistance, or piezoelectric properties, generating a measurable electrical signal.

Q3: What output signals does the digital differential pressure sensor support? ❯

Available signal types include 4-20mA, 0-5V, 0-10V, and RS485, making it easy to connect to various control and monitoring systems.
