Lunte specializes in the design and manufacture of temperature sensors and nuclear measurement instruments, involved in industries such as industrial, nuclear power, and is recognized as a national-level "little giant" enterprise and a "hidden champion" enterprise in Zhejiang Province.
The bimetallic thermometer is a field measurement instrument suitable for measuring medium and low temperatures, capable of directly measuring the temperature of gases, liquids, and steam. This thermometer is characterized by its low cost, easy installation, and the ability to read measurements on-site, making it a partial replacement for other types of measuring instruments. It is widely used in industries such as petroleum, chemical, steel, and power generation.
Product Overview
The working principle utilizes two metals with different coefficients of thermal expansion bonded together. One end is welded to a fixed point, while the other end twists and deforms as the temperature changes, converting this deformation into a deflection angle of the pointer, which indicates the temperature.
According to the structure, it can be divided into universal type, axial type and radial type. According to the function, it can be divided into luminous, remote transmission and electric contact, etc.

Recommended Products
Used for temperature measurement at the top of coke oven regenerators, with a thermocouple insertion depth of nearly 2 meters. It features a reinforced square box and support ribs to prevent deformation when installed horizontally in high-temperature environments. The adjustable insertion depth is facilitated by a movable flange connection.
Sheath of flexible thermocouple is drawn by special stainless steel in special process, so it is muchsofter thantraditional ones, but the performance is same, despite of flexibility. Flexible thermocouple can be inserted intozigzag thermowell and measure temperature of various structure inner the reactor.
