Further areas of application include processing with changing media in which residues could cause mixing or contamination of the media. Like the standard model, HDA 4700 with a flush membrane for relative pressure measurement in a high pressure range via a stainless steel measurement cell with a thin film DMS.
The pressure connection is completed at the front with a fully-sealed stainless steel membrane and filled internally with a pressure transfer fluid, which transfers the process pressure to the measurement cell hydrostatically.
The output signals 4 .. 20 mA or 0 .. 10 V facilitate connections to all HYDAC measurement and control devices as well as connection to standard evaluation systems (e.g PLC control units).
- Flush front pressure connection
- Accuracy ≤ 0.25 % typ.
- Extremely robust sensor cell
- Very accurate temperatures
- Excellent EMC characteristics
