Acid and Alkali RTD - With Teflon Coating

RAA310 / RAA312 / RAA320

Teflon Coated RTD sensors are designed to measure temperature in highly corrosive acids and alkalis. The RTD sensor measures temperatures up to 200 °C. The sheath is constructed of SS316 / SS316L and then Teflon (PTFE) coated to protect the RTD element from corrosion and heat degradation by the acidic or alkaline medium. An optional Teflon coated Titanium Sheath will give the product an even longer life. Angular assemblies are available on request which enable the RTD sensor to be installed in complex positions. Its 3-wire Pt100 RTD element can be constructed in single or dual assembly in Class B as per the IEC 751 standard for RTD sensors.The standard terminal head is made of plastic; polypropylene (PP) heads can also be designed on request.
