HDA 4700-HC Electronic Pressure Transmitters with HCSI sensor recognition

To extend the number of sensors on the HMG 4000, the special CAN-based HCSI sensors were developed. The HCSI sensors, easily identified by their red type label, are automatically recognized along with all their characteristics by the HMG 4000.

Up to 28 HCSI sensors can be connected to the HMG 4000 via the Y-distributor (available as an accessory) to set up an HMG-internal bus system. The data are transmitted using CAN-based bus protocol.

Like all pressure transmitters of the HDA 4700 series, the HDA 4700-HC also has a very accurate and robust sensor cell with a thin-film strain gauge on a stainless steel membrane.

Due to their outstanding temperature and EMC characteristics, together with their compact dimensions, these instruments can be used in a wide fi eld of applications in the mobile and industrial sectors.

Special features:

• Fully automatic recognition by, and voltage supply from, HYDAC measuring instruments HMG 4000
• Automatic transfer of measuring range, measured value and measurement unit
• Accuracy ≤ ± 0.25 % FS B.F.S.L.
• Highly robust sensor cell
• Very small temperature error
• Excellent EMC characteristics
• Excellent long term stability
• Very compact design
