Sanitary RTD with Ingold Port


Sanitary RTD sensors with ingold port are designed to be used in sterilizers, bio-reactors , food, dairy, beverage, pharmaceuticals and chemical industries, where hygiene takes top priority. The ingold port fitting offers a clean instrumentation mounting without compromising on the ease-of-use of a removable sensor. In gold port connections are bore cylinders that are welded to tanks into which plugs with O-ring seals are installed. This design has the flexibility to specify the O-ring location to minimize the “dead” space, which allows a clean installation. The ingold solution is ideal for sanitary vessels and fermentation applications. The RTD sensor is built with SS316L sheath. As the sheath does not bend, a sheath length greater than 300 mm is not recommended. The sheath terminates into a die cast, weatherproof aluminium head. The RTD sensors measure temperatures between -50 and 200°C. Its 3 wire Pt100 RTD element can be constructed in single or dual assembly in Class A/Class B as per the IEC 751 standard for RTD sensors. The terminal head of the RTD sensors has a standard 1/2” BSP (F) single cable entry and a single compression cable gland with the option of dual cable entry and double compression glands. Stainless steel terminal heads or transition joint assemblies can also be constructed.
