The BT8000 Series intelligent level transmitter is a high-reliability submersible level measuring instrument designed for continuous monitoring across hydrology, municipal water supply, petroleum, chemical, and geological exploration industries. Built with a high-quality silicon piezoresistive sensing element, it features full-range digital linear calibration and digital temperature error compensation across the complete operating range.
To guarantee zero maintenance in field conditions, compensation parameters are securely stored in non-volatile memory to eliminate calibration loss. Integrated power monitoring and watchdog timer circuits prevent program crashes, while the fully sealed stainless steel IP68 enclosure delivers maximum stability in harsh aquatic and chemical environments.
2. Main Features
- Advanced Digital Compensation: Digital linear and thermal calibration with no mechanical potentiometer drift caused by vibration.
- Smart Circuit Protection: Built-in watchdog timer, power-supply monitoring, anti-surge protection, EMI suppression, and reverse-polarity protection.
- Non-Volatile Memory: Calibration parameters are stored safely to prevent data corruption or loss.
- Standard Industrial Output: Two-wire 4–20mA current loop system for effortless DCS/PLC integration.
- Rugged & Explosion-Proof: Fully sealed IP68 construction (316L optional) with Exia ⅡC T6 intrinsically safe compliance.
