METHOD TO CONTROL QUALITY OF INSTALLATION OF INTERNAL REACTOR HEAT SENSORS

摘要

FIELD: measurement equipment.SUBSTANCE: method to control quality of installation of internal reactor heat sensors includes input of a heat sensor into a thermal control channel, comprising a tip of smaller diameter with a seat and heating of a sensitive element by passing an electric current pulse via heat electrodes. Duration of heating is chosen as not more than the index of thermal inertia of the heat sensor. The cooldown thermogram is registered. As the heat sensor is input, additional thermal resistance is created between its working end and seat by fixation of the working end in the "failure to reach" position to the seat. Heat sensor readings are registered both in process of heating and in process of subsequent spontaneous cooling of the sensitive element, at the same time the working end is sent to the seat.EFFECT: production of valid data about quality of installation of internal reactor heat sensors.2 cl, 3 dwg
