Product introduction

The PN53 series micro differential pressure transmitter adopts a thermal-type low-pressure sensor core. It utilizes a micro-flow channel integrated into the sensor chip to detect airflow changes and determine air pressure.

PN53 features strong overload capacity, excellent electromagnetic interference resistance, wide measuring range, and multiple signal outputs. It is widely used for measuring air or neutral gases in systems such as HVAC, process control, environmental monitoring, clean rooms, and other applications requiring micro differential pressure detection.

Note: The selection guide is for parameter selection only. Final product configuration is defined by corresponding factory code.

The pressure sensing core is calibrated at a reference absolute pressure of 1Bar (100,000Pa). As the sensor uses a thermal principle, altitude/atmospheric pressure variations affect output. Use the following formula to compensate:
ΔPeff = ΔPsensor × (100,000Pa / Pabs)
Where:
ΔPeff = compensated micro pressure difference
ΔPsensor = current output from the sensor
Pabs = absolute pressure at installation location (i.e., local atmospheric pressure in Pa)
