The ISA Controls Well 8783/SS90 is a precision-machined thermowell used to house and protect temperature measurement probes such as RTDs, thermocouples, and temperature transmitters. Installed directly into piping or vessels, this well isolates the sensing element from direct process contact, enabling safe removal for calibration or replacement without shutting down the system.

Constructed from high-grade stainless steel, the 8783/SS90 model delivers excellent resistance to corrosion, chemical exposure, and elevated temperature conditions. Its robust mechanical strength provides enhanced protection against fluid velocity, mechanical stress, and pressure effects.

Commonly utilized in oil & gas, petrochemical, power generation, and process manufacturing, this ISA Controls thermo well contributes to long-term measurement stability, equipment longevity, and overall process safety.
