300140940 Union Ball Valve Industrial Water Treatment PVC 150PSI Corrosion-Resistant Valve

1. Sanitary Conductivity Sensor with Integrated Temperature Compensation​

The GF Signet 300140940 is a hygienic conductivity sensor engineered for precision measurement in pharmaceutical and biotechnology applications requiring EHEDG compliance. Featuring a ​four-electrode measurement principle​ and ​PEEK/316L stainless steel construction, this device delivers ​​±0.5% accuracy​ across ​0.1–2000 mS/cm ranges​ with ​​≤5s response time. Its ​IP68-rated housing​ withstands ​150°C SIP cycles​ and ​chemical exposure​ while meeting ​ASME BPE standards. The sensor incorporates ​integrated PT1000 temperature compensation​ and ​auto-ranging capability​ for seamless operation across varying conductivity levels. Designed for WFI (Water for Injection) systems, CIP monitoring, and buffer preparation, this sensor provides ​cell constant verification​ and ​contamination detection​ through advanced diagnostics. Certified for ​​-20°C to +130°C operation, it enables ​long-term stability​ with ​**>12-month calibration intervals**​ in most applications.

​2. Critical Applications & Technical Advantages​

This conductivity sensor excels in mission-critical processes including ​WFI quality verification​ (<1.3 μS/cm at 25°C), ​CIP chemical concentration monitoring​ (0.5–5% NaOH), and ​buffer dilution control. Key advantages include ​four-electrode technology​ eliminating polarization errors, ​316L stainless steel electrodes​ resistant to corrosive cleaners, and ​smooth surface finish​ (Ra≤0.8 μm) preventing biofilm accumulation. The sensor's ​integrated temperature compensation​ ensures accuracy across ​0–100°C​ without external probes, while ​auto-cleaning readiness​ supports ultrasonic cleaning attachment integration. With ​**>24-month service life​ in aggressive chemicals and ​quick-disconnect tri-clamp fitting**, it reduces maintenance downtime. The device's ​gold-plated contacts​ and ​EMI-shielded cable​ ensure signal integrity in electrically noisy environments.

​3. Advanced Functionality & Compliance Features​

​Measurement Integrity​ utilizes ​four-electrode technology​ with ​frequent automatic calibration verification​ and ​temperature-compensated readings​ referenced to 25°C. ​Smart Diagnostics​ include ​electrode fouling detection​ through impedance monitoring and ​platinum coating degradation​ assessment via frequency response analysis. ​Hygienic Design​ features ​crevice-free construction​ meeting EHEDG Class I criteria and ​drainable housing​ preventing fluid entrapment. ​Compliance Coverage​ includes ​3-A Symbol 74-03, ​FDA 21 CFR 177.2600​ materials registration, and ​EC1935/2004​ for food contact materials. The sensor's ​pre-amplified signal output​ enables long cable runs without signal degradation, while ​optional MODBUS/Profibus output​ facilitates direct PLC integration. ​ATEX Zone 2 certification​ allows deployment in hazardous areas with flammable solvents.
