1. Digital Circuit Design: Ensure the system is steady with strong anti-interference.
2. Connector Design: the system is optic coupled with 6 optic sensors which complies with API standard and one ground bolt.
3. Compatibility: compatible with optic sensor for many brands, such as Sentry, Chevron, Liqui, Dixon.
4. Self-Checking: ensure more safety.
5. Standard Design: design the plug in accordance with API standard,match to API socket.
6. Static Electricity: reduce the electrostatic ground resisic which during truck body and ground less than 550Ω.
7. Voice Light Alarm Signal: control the system working situation timely.
8. Different capacity available: relay switch signal output,the interface capacity 250VAC/30VDC.
