DPT20 Differential Pressure Transmitter
Model: DPT20
The DPT20 measures air and non-combustible, non-corrosive gases in ranges from 0–10 to 0–250 mm WC (bi-directional) and is configured with its front keys. It is intended for HVAC systems, clean rooms and general industrial applications.
- Easy panel mounting
- Ranges from 0–10 to 0–250 mm WC, bi-directional
- Configuration via keys
- Version with inbuilt buzzer or with 4–20 mA output
- Push-on connections for 3/16" tubing
