Differential pressure transmitter

Relative and differential pressuretransmitter 450
Type 450
The pressure transmitter type 450 is a robust sensor integrated in a compact housing for the use in various applications
with air or neutral gases. Pollutions with small particles do
not harm the function of this pressure transmitter.
The type 450 is ideal for HVAC applications.
Additionally to the analogue output the pressure transmitter
type has a digital output I2C. These output signals are temperature compensated, linear and reinforced.
The transmitter is fitted directly on a PCB.
