Core Functions of The 9008373 02 UV Transmitter on PureBallast EX BWTS
1. Real-Time UV Dosage Monitoring
With an ultra-wide 0–3000 W/m² range, this EX2C transmitter precisely tracks UV intensity from clear offshore seawater to turbid nearshore water. Its intrinsically safe circuit eliminates spark risks in flammable vapor zones, meeting USCG ≥772 W/m² and IMO ≥252 W/m² minimum compliant UV thresholds.
2. Intelligent Lamp Power Optimization
Real-time UVI data enables the LDC 3.1 Ex cabinet to dynamically adjust 6kW UV lamp output (50–100%):
Clean water → reduced power → extended lamp life
Turbid water → full power → maintained disinfection dosage
3 Automatic Flow Control
Combined with EX flow meter and V201-8 control valve:
USCG Mode: Flow auto-limited when UVI < 772 W/m²
IMO Mode: Flow capped when UVI < 252 W/m²
4 Predictive CIP Maintenance
Declining UV readings trigger the 30-hour mandatory CIP cycle reminder on the HMI—preventing W140 overdue alarms and invalidation of type approval.
5 Fault Diagnosis
Instantly detects UV lamp failure, cracked quartz sleeves, or fouling—then automatically reduces rated flow and logs fault data for PSC audit traceability.
Question You Might Concern
Q1: What is the part number for the Alfa Laval PureBallast EX UV intensity transmitter?
A: The correct part number is 9008373 02 (model EX2C SUV 20.2 Y2 C 40°), measuring 0–3000 W/m².
Q2: What BWTS models is this sensor compatible with?
A: It fits all Alfa Laval PureBallast EX 1000, 1500, 2000, and 3000 USCG & USCG HP reactors with 6kW medium-pressure UV lamps.
Q3: Do I need field calibration after installation?
A: No. All FiverUVC transmitters are factory pre-calibrated against standard UV light source—no on-site calibration required.
Q5: What happens if I use a bad quality replacement sensor?
A: Bad quality sensors may trigger W151 low UV alarms, void type approval, limit treatment flow, and risk PSC detention.
Q6: How does the UV transmitter help with regulatory compliance?
A: It provides continuous UV intensity logging—creating a digital audit trail for USCG, IMO, and port state control inspections.
Q7: What is the measuring range of this sensor?
A: 0–3000 W/m²—suitable for both clear offshore and turbid nearshore water conditions.
Q8: Can I replace the sensor myself?
A: Yes. It is 1:1 OEM compatible—identical dimensions and wiring. However, we recommend consulting a qualified marine engineer or our
technical support team.
