Abstract
The utility model discloses a platinum resistor temperature sensor, which comprises a junction box, a junction box joint, a platinum resistor reinforcement tube, a sensor protective tube, a thin film platinum resistor element, a direction-adjusting nut, a pressure-resistant protective base and a sealing cushion. The cable outlet direction of the junction box can be randomly adjusted by the direction-adjusting nut, thereby facilitating simplification of the complexity of wiring and beautification of the mounting process. The pressure-resistant protective base, the junction box and the platinum resistor reinforcement tube adopt a split-type structure, thereby realizing repair, verification and replacement of the platinum resistor temperature sensor without closing pipeline flow of the platinum resistor temperature sensor. The thin film platinum resistor element is embedded in the sensor protective tube through epoxy resin, and the periphery of the thin film platinum resistor element has no air gaps, thereby effectively resolving the problem of moisture condensation.
