Differential Pressure Smart Sensor
Overview
The differential pressure Smart Sensor extension clips on to
the bottom of your Smart-Vue Pro data logger enabling you to
compare the difference in pressure between two physically
separated spaces. The sensor detects the difference in
atmospheric pressure between where the Smart-Vue Pro is
located and other spaces.

Usage
The Differential Pressure Smart Sensor is often used for
monitoring in two different types of laboratory scenarios. In
many laboratories, ambient air pressure is used to control the
direction of particle flow. The differential pressure data logger
is placed outside the cleanroom so that people know it is safe
to enter, as shown in these two examples:
1. High pressure cleanrooms such as vaccine and organ
transplant laboratories in which the ambient pressure is
higher than the neighboring room, hallway or airlock in
order to help keep particles from entering the cleanroom.

particles from flowing in
2. Low pressure cleanrooms such as virology laboratories in
which the ambient pressure is lower than the neighboring
room, hallway or airlock in order to help keep particles
from exiting the cleanroom.

particles from flowing out
You may cascade pressure control with an airlock before
entering the cleanroom. Two differential pressure sensors
could be used in this case.
CAUTION:
The USB port on the side of the
Smart Sensor is not used at this time.
