Model 228 Insertion/Submersion Toroidal Conductivity Sensor

---

MOULDED of Polypropylene, or glass-filled PEEK or glass filled Tefzel. INTEGRAL RTD for temperature compensation

FEATURES AND APPLICATIONS The Model 228 is available in two materials: PEEK, and Tefzel,1 for optimal corrosion and temperature resistance. Polyetheretherketone (PEEK) provides excellent corrosion resistance and is available in standard temperature (120°C) and high temperature (200°C) versions. The Tefzel1 version is ideal for use in highly concentrated oxidizing acids (H2SO4, HNO3) and Hydrofluoric acid (HF). Note: PEEK and EPDM are not suitable for these acids. The Model 228 features rigid construction that will stand up to high vibration applications such as oil well drilling mud shaker trays. A single piece 304 SS tube supports the toroid coils and reinforces the threaded mounting shaft. This subassembly is then molded in chemically resistant plastic. There are no seams or welds that can crack and cause leakage and subsequent failure. 1 Registered Trademark of E. I. du Pont de Nemours & Company
