FUNCTION
Functional description
Static differential pressure transducers function according to the static differential pressure measurement principle. The
sensor is a cylinder that consists of two chambers (one for positive pressure and one for negative pressure) separated by
a diaphragm. If there is equal pressure in both chambers, the diaphragm is in the middle between the chambers and is
not deformed. If there is a pressure difference, the diaphragm deforms towards the chamber with the negative pressure.
The degree by which the diaphragm deforms is a measure for the differential pressure. This is why the voltage signal is
proportional to the differential pressure.
Principle of operation – room pressure control
① Controller EASYLAB TCU3 or LABCONTROL TCU-LON-II
In a lab, the room pressure transducer is typically linked to the supply air controller; in a clean room, it is linked to the
extract air controller.

Installation details
INSTALLATION DETAILS
Installation and commissioning
Choose a suitable installation location (reference room with stable pressure)
Ensure sufficient cross section and careful placing of the measuring tubes
Connect the differential pressure transducer to the controller or monitoring system
Supply voltage from the EASYLAB TCU3 controller or TCU-LON II (supply voltage for the differential pressure
transducer must be equal to the supply voltage provided by the controller)
Cosider the warm-up time of the sensor
Do not install the sensor near sources of interference such as transformers, senders, motors, or heat sources
Choose a stable installation location as shocks or vibration may distort the output signal
Installation should be vertical, with connections pointing downwards; this installation position corresponds to the
factory setup for calibration; it also prevents the ingress of condensate from the pressure tubes.
