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.
Multipoint Thermocouple and RTD
Multipoint Thermocouple (Resistor) is suitable for production sites where temperature gradients are not significant and where simultaneous measurements at multiple locations or multiple measurements at a single location are needed. It is widely used in devices such as synthesis towers, reactors, and storage tanks. Based on the structure, it can be classified into integrated temperature sensing elements and separately removable types.
A multi-point flexible thermocouple suitable for temperature measurement in butanediol (BDOsynthesis reactors, with a maximum operating pressure rating of 2500 # (design pressure of 34.8MPaand design temperature of 204 '℃), and equipped with a pressure instrument for leakage detection.
It is used in coal-water slurry water-cooled wall gasifier (Tsinghua furnace, Jinhua furnace, Luxi furnace, etc.); There are 3 temperature sensors, two K-type and one B-type, the K type is used to measure the temperature of the annular cavity and the water wall temperature, and the B type is used to measure the temperature of the furnace combustion chamber, and the double-layer anti-leakage and detachable structure are set.
Our company has a variety of multi-point thermocouples suitable for ethylene glycol reactors. According to the process requirements, it can be divided into: single branch multi-point, multi-branch multi-point; Fixed, core-pullable, leak-proof and so on.
It is suitable for temperature measurement inside various reactors, especially hydrogenation reactors, with multiple independent casings fixed with T-beam brackets to prevent casing from bending, and equipped with sealing chambers and leakage detection pressure gauges.
The cross-shaped temperature measurement thermocouple is a product developed by our company for measuring the temperature at the top of the blast furnace. Four sets of thermocouples are arranged in a cross layout, allowing for maintenance and replacement of thermocouples without shutting down the furnace. The thermocouple is held firmly against the inner wall of the casing by a spring, ensuring more accurate temperature measurement and more sensitive response.
The thermocouple is flexible and can be bent. The product uses three different sealing methods and a four-layer leak-proof structure, with a double-layer independent sealing chamber. It is also equipped with a pressure gauge or pressure sensor for monitoring.
The multipoint thermocouple is sealed with high-pressure sealing filler and metal compression fittings. A protective cover is installed beneath the flange surface to prevent the accumulation of dust at the flange root of the mounting tube from causing hydrogen embrittlement and corrosion of the thermocouple.
insertion depth can be adjusted ±250mm. The casing is a stainless steel bellows with a pressure resistance of 1MPa. The head is equipped with a fastening block for attaching to the hammer.
The single multi-point thermocouple produced by our company is a plurality of thermocouples in an armored tube, which is made by pulling the armor directly through the porous magnesium oxide column through multiple coupling wires, which has the advantages of flexibility, voltage resistance, leakage prevention, etc., and the thermocouple is a flexible structure.
RTD is flexible and bendable; The length of a single stick can reach up to 150m; With special mounting components, the thermal resistance in the interlayer in the storage tank, the inner and outer tank walls, the purge pipe, the bottom of the inner tank and other positions can be effectively installed and fixed
With special installation components, the RTD in the interlayer. inner andouter tank walls, purge pipe, and inner tank bottom can be effectivelyinstalled and fixed.With special installation components, the RTD in the interlayer. inner andouter tank walls, purge pipe, and inner tank bottom can be effectivelyinstalled and fixed.
