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.
Thermocouple And RTD
Thermocouples and thermal resistors are commonly used with display instruments and computers to directly measure the temperature of liquids, steam, gas media, and solid surfaces in various production processes within the range of -40°C to 1600°C. Due to their simple structure, low cost, and easy maintenance, they are widely used in industries such as petroleum, chemical, steel, and power.
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.
The spring structure makes measuring end of spring loaded thermocouple or RTD adiustable. The adjustablerange of insertion length is about 15mm. Measuring end sticks to top of thermowell, making measurement fastand accurate. Spring loaded thermocouple or RTD is applicable to all kinds of thermowell.
It is suitable for temperature measurement of rotary kiln and other equipment, and the wireless temperature measurement system can transmit the temperature measurement signal remotely and wirelessly, and the wireless receiver has a display function.
It is used for direct measurement of various medium and high pressure small diameter (DN15~DN150) pipes.
It is suitable for temperature measurement and control in ultra-high pressure places in the production process of petroleum and chemical industry, especially in high-pressure polyethylene production equipment. The product is welded and sealed with double-layer packing, which can be used under 300MPa working condition for a long time.
Sectional connection can be used, the high temperature section uses a metal armor layer, and the non-hightemperature section can use high temperature compensation wire excess.
polypropylene (PP) plant reactor; It has a double-layer leak-proof structure; The measuring end is in direct contact with the medium, with fast response and high precision; The thermal response time is τ0.5<3s.
Thermowell of chemical fiber purpose RTD has a shrink structure. lt is thin in measuring end, so the sensortouches media wel, making measurement fast-response and accurate. Chemical fiber purpose RTD matchesthe requirement of low pressure and high accuracy in chemical fiber industry.
RTD Inside of measuring end Special cling structure (patented technology), it is applicable to occasion ofintense vibration.
With scale on the thermowell, thermocouple or RTD is applicable to the occasion of low tightness.Insertion length is adjustable by movable compression thread.
Right-angle thermocouple is applicable to high temperature production field. On occasions that gasesdo harm to connection head or thermocouple can not be installed horizontally or vertically, right-anglethermocouple is also suitable. Process connection: movable flange or movable compression thread.
Indoor thermometer is applicable to cold storage, oasthouse, thermostatic chamber, air-conditioned roomcommunications room, warehouse and other indoor or outdoor room which needs to control measurementIt measures accurately and is easy to install.
The casing or component of the corrosion-resistant thermocouple (resistance) is wrapped in polytetrafluoroethylene, known as the "king of plastics." It is resistant to the corrosion of most acids, alkalis, and organic substances. With a temperature measurement range of <200°C, it can replace expensive metal protective tubes such as high-nickel alloys, titanium, and tantalum. It has advantages such as low cost and ease of processing.
