1. Product Overview
The +GF+ Signet 159 001 826 is a high-performance ultrasonic level transmitter engineered for continuous non-contact liquid level measurement in demanding industrial environments. Featuring a PVDF sensor housing with IP68/IP69K protection, this device withstands corrosive chemicals, high-pressure washdowns (up to 100 bar), and extreme temperatures from -40°C to +80°C. Its advanced 75kHz ceramic transducer delivers precise measurements up to 10 meters with ±1% accuracy, even in challenging conditions with foam, vapor, or agitator interference. The sensor incorporates IntelliTrack™ echo processing to filter false signals and automatic temperature compensation. Designed for SIL 2 applications per IEC 61508, it offers dual-output options (4-20mA HART/RS-485 Modbus) and comes with a 1.5" NPT process connection for versatile tank mounting. Ideal for water treatment, chemical processing, and food manufacturing.
2. Key Technical Parameters
- Measurement Range: 0.25–10 m (liquid), 0.15–5 m (solids)
- Accuracy: ±1% of reading or ±3mm (whichever is greater)
- Beam Angle: 8° narrow beam (-3dB point)
- Output Signals: 4-20mA HART + RS-485 Modbus RTU
- Process Connection: 1.5" NPT male (316L SS)
- Pressure Rating: 3 bar @ 20°C (4 bar peak)
- Temperature Compensation: Integrated PT1000 sensor
- Electrical Protection: Reverse polarity, 4kV surge, short-circuit
- Certifications: ATEX/IECEx Zone 0 (Gas), Zone 20 (Dust), SIL 2
- Housing Material: PVDF (Kynar®) with Viton® seals
3. Primary Applications
This sensor excels in critical industrial scenarios:
- Wastewater Treatment: Sludge level monitoring in clarifiers with heavy foam
- Chemical Processing: Concentrated acid tank measurement (up to 98% H₂SO₄)
- Food & Beverage: CIP-compliant level control in dairy processing tanks
- Pharmaceutical: USP Class VI-certified bioreactor level monitoring
- Power Generation: Cooling tower basin level management
- Pulp & Paper: Stock tank control with steam compensation
- Mining: Leachate level tracking in tailings ponds (pH 1-14 resistance)
- HVAC Systems: Glycol solution monitoring in district cooling plants
Its PVDF construction resists chlorine, hydrocarbons, and caustic solutions while maintaining accuracy in temperatures from freezing brine solutions to hot process liquors.
