Sea friends, please recommend some domestic temperature-sensitive brands!

It would be better if the question were more specific – are you installing it on-site or inside a control room cabinet?

If you clarify the technical requirements and recommend specific model products, it will be more reliable; at least you can compare the differences and advantages of each one. . Brands are like farts; I’m recommending some utterly worthless “farts” to you – they’ll knock you out, which can also be considered an accident. . . . . . {:3_51:}

There’s no need to use domestic temperature sensors; if you can afford it, use imported temperature sensors combined with domestic thermal resistors – the performance is quite good. If you want to use a complete set made in China, then it’s up to you; the quality of these products is more or less the same. Anhui Tiankang, Chuanyi, Shangziyi – there are many others

Beijing Guancheng Industrial Measurement offers a wide range of products, excellent quality, and competitive prices! 18513000810

For temperature control, imported products are still necessary; it is recommended to use Emerson-brand products. Domestic manufacturers such as Anhui Tiankang, Zhejiang Lunte, Shangziyi, and Chuanyi also produce high-quality products

Let’s take a look at the brands used by CNPC: Serial Number, Supplier Name, Grade, Remarks. 1. Shenzhen Te’an Instrument & Equipment Sales Co., Ltd. – Grade A; 2. Chongqing Chuanyi Automation Co., Ltd. – Grade A; 3. Zhejiang Aoxin Instrument Co., Ltd. – Grade A; 4. Suzhou Lanlian Fuji Instrument Co., Ltd. – Grade A; 5. Fujian Shangrun Precision Instrument Co., Ltd. – Grade A; 6. Zhonghuan Tianyi Co., Ltd. – Grade A; 7. Daqing Maghua Instrument & Scale Co., Ltd. – Grade B; 8. Daqing Oilfield Automation Instrument Co., Ltd. – Grade B; 9. Fuzhou Foguang Baitai Automation Equipment Co., Ltd. – Grade B; 10. Jilin Jihua Group Instrument Co., Ltd. – Grade B. International brands: 1. Beijing Yuandong Instrument Co., Ltd. – Grade A; International brand 2: Shanghai Azipell Control Instrument Co., Ltd. – Grade A; International brand 3: Shanghai Foxboro Co., Ltd. – Grade B; International brands

If by temperature variation we’re talking solely about the temperature variation modules, then those used by CNPC – well, I think they’re completely useless :Bro P thinks that the temperature-sensitive module he developed over a decade ago is far better than theirs. . . Alas~~~ it’s a pity that our village chief doesn’t allow us to sell the modules separately. Then let you guys evaluate the whole temperature-controlled unit.:lol

Cologne is good – it offers a good value for money and high quality as well. Domestic production

This is a high-quality temperature transmitter: the YR-ER213 intelligent temperature transmitter is manufactured by Changhui Instruments using American technology. It is suitable for handling signals from thermocouples (TC), resistance thermometers (RTD), and linear resistors (Ω), isolating the input signals and converting them into a 4-20mA two-wire output. Install the intelligent temperature transmitter and upgrade the sensor in the temperature sensor junction box to an integrated temperature transmitter ； The intelligent temperature transmitter is installed in a dedicated junction box, and can be mounted in industrial sites in horizontal, vertical, wall-mounted, or pipeline-mounted configurations (it can also display readings on-site when equipped with an LCD display) ； An intelligent temperature transmitter can upgrade a level gauge to a remote-transmission two-wire magnetic flap level gauge (or float level gauge) by receiving its resistance signal.
