Description

Multipoint thermometers are commonly used to measure temperature curves in reactors or fuel depots, or to detect so-called "hot spots." To obtain a fast response time, the individual measuring points are pressed to the inside of the tube well by a pressure spring, which forms an integral part of the thermometer or, ideally, an already present component of the reactor. The connection terminal or temperature transmitter is placed in the connection housing, which can be a component of a multi-point thermometer or can be mounted separately on a wall or pipe. The DS71 offers excellent reliability, practicality and safety. It can use multiple measurement points to perform a variety of temperature measurements throughout the reactor, while providing flexibility for installation. In addition, this flexibility ensures that the sensor tip remains in continuous contact with the inner wall of the bend, even in the event of bending deformation. These characteristics, along with replaceability, speed of response, bimetallic drive, and point density have made the design a standard used throughout the industry, and the purge design utilizes a thick-walled center support tube that provides purge gas throughout the entire length of the pipe and the entire length of the pipe. The purge protects the internal sensors of the tube well and the thermocouple.
