Technical Features
• Compact pressure sensors for industrial applications in liquid and gaseous substances.
• Piezo-resistive, flexibly suspended silicone measuring cell in an oil-filled, all-welded special steel enclosure.
• The stable mechanical construction provides a reliable protection for the measuring cell against the test substance and immunes it against pressure peaks and vibrations.
• Absolute pressure: pressure related to vacuum (0 bar).
Programming Specification
| Calculation of the refrigerant temperature with device special version SB0000R2 The ALMEMO® Version V6 devices (2590-2/-3S/-4S, 2690, 2890, 8590, 8690, 5690) can be used a for continuous temperature measurement (resolution 0.1K) with absolute pressure sensors (resolution 0.001 bar compulsory). Both pressure and temperature can be selected or continuously indicated and recorded. | |||||
