Features
- Silicon-oil filled sensor element (diffused silicon)
- Sealed-gauge (sealed gage) pressure sensing
- Fully welded construction (no O-rings, no leakage risk)
- Anti-condensation design for humid environments
- Protection against forward and reverse overvoltage
Applications
- Industrial refrigeration units
- Multi-split and VRF air conditioning systems
- Precision computer-room air conditioning
- Inter-row / aisle cooling systems
- Air-source heat pumps
Performance specifications (reference conditions)
- Test/reference temperature: 20–25 °C
- Reference power supply: 5 VDC
