QBE64-DP4 PRESSOR SENSOR

Description

The QBE64-DP4 is a Siemens differential pressure sensor designed for measuring pressure, vacuum, and pressure difference in HVAC systems, water circuits, and industrial air/liquid applications. It converts differential pressure into a standard analog signal for use in building automation and control systems.

This sensor is commonly used in air handling units (AHU), filters, pumps, and flow monitoring systems where accurate pressure feedback is required for system control and efficiency.
