Siemens QBM3230U03UD Air Differential Pressure Sensor,
The Siemens QBM Series Air Differential Pressure
Devices use a proven sensing technology to delivery
accurate and repeatable data in applications that require
monitoring of differential pressure.
Applications
QBM Series Differential Pressure Devices can use in a wide range of HVAC and general building
management applications where differential air pressure
monitoring in required.
Typical applications for the QBM3230 include control of
variable speed fans in VAV systems and monitoring of
pressure differentials in clean room applications.
The QBM81 can be wired NO or NC and provide a digital
output with adjustable differential pressure trip point.
Common applications include monitoring of air filters
and general indication of high/low differential pressure
situations.
