2. Product description
The differential pressure sensor DS85P is used to measure small differential pressures
of non-aggressive gases, especially air.
2.1 Intended use
The area of application is, for example, air conditioning technology, room pressure mon-
itoring or filter control. A signal of 0...10 V DC is available to the user as an analogue
output. The area of application is, for example, in air-conditioning technology for the con-
trol of fans, room pressure monitoring or filter control.
2.2 Functional description
A soft silicone diaphragm with a corresponding measuring spring is used as the sensor,
which is fine-tuned to each measuring range. The deflection of the diaphragm is meas-
ured contactless with a differential transformer and converted into a standardized output
signal by the electronics. The ranges from 0...50 Pa to 0...6000 Pa are covered by three
measuring range groups, and in each device group four calibrated measuring ranges
can be selected via a 2-pole DIP switch.
3. Montage
The differential pressure sensor DS85P is designed for wall mounting. Please consider
the following factors when selecting the location:
•
The mounting surface must be sufficiently firm and vibration-free.
•
The environment must comply with the climatic conditions specified in the
technical data.
VORSICHT
Material damage
