Differential pressure transmitter 450
The differential pressure transmitter Type 450 is a robust sensor housed in a compact casing, making it ideal for use in a wide range of applications with air and neutral gases. Contamination by small dust particles poses no problem for this transmitter. The Type 450 is particularly well-suited for HVAC applications.
In addition to the analog output, the Type 450 is also available with a digital I²C output. The output signals are temperature-compensated, linear, and amplified. Installation is straightforward and can be done directly onto a PCB.
- Suitable for low-pressure ranges
- Excellent accuracy and long-term stability across the entire measuring range
- Output signal temperature-compensated from -10 … +80 ºC
