Immersible 260C RTD permits immersion in aggressive chemicals. PFA fluorocarbon molding ensures chemical sealing at high temperature. The two- or three-wire flat design fits through 1.4-mm gaps and is flexible for surface mounting. The sensors are also refractory-sealed for ±0.05C stability. The RTD allows the process tighter control and minimizes calibration expense because of its stability. Applications include those that need accurate temperature measurement under high humidity or submerged conditions.
