I need to replace 2 Ashdown Control pressure transmitters in an existing system. The part numbers are
- DNXD1G860, range 0-40kPa gauge
- DNXD1G870, range 0.60kPa gauge
As a minimum I need to find spares, but preferably I would like to replace with transmitters that have an improved zero drift. What can you offer?
The DMP331 uses silicon strain gauge technology which should have better zero drift than the DNX which is based on older stainless steel diaphragm LVDT technology.
Please note that unlike the DNX, the DMP331 is a fixed range device and not adjustable.
