Description

Temperature probe detection rod

Technical Field

The utility model relates to a graphite furnace technical field specifically is a temperature probe detects stick.

Background

A graphite furnace: also called graphite resistance furnace, can control the temperature of the heating area of the optical fiber prefabricated rod very precisely. Fluctuations in the temperature gradient in the region of the glass softening temperature lead to an unstable fiber diameter.

The infrared temperature measuring probe must be over against the hottest area of the heating body to monitor the temperature all the time.

The temperature of the graphite furnace (heating the optical fiber preform device to 2100 ℃) is monitored by a temperature measuring probe (directly facing to a middle hole phi 14mm of the heat-preserving barrel). At present, the heating body needs to be taken out when the graphite furnace is cleaned, the heating barrel is probably touched, the hole position of the temperature measuring probe is not aligned due to the movement of the heating barrel, and therefore the temperature measurement is inaccurate. If the temperature measurement is inaccurate, the temperature measurement is abnormal after the graphite furnace is started, the furnace needs to be stopped, and the furnace is disassembled and reassembled after the graphite furnace is cooled.
