其結(jié)構(gòu)設(shè)計緊湊,雙支設(shè)計可同時提供兩路獨(dú)立的測量信號,互為備份,增強(qiáng)了測量的可靠性和安全性。在安裝方面,它配有適配多種安裝方式的接口,無論是固定在墻壁、管道還是其他結(jié)構(gòu)上,都能輕松實(shí)現(xiàn)穩(wěn)固安裝,且安裝過程簡便快捷,無需復(fù)雜工具與技術(shù)。
在性能表現(xiàn)上,它對溫度變化的響應(yīng)迅速,能夠及時捕捉室內(nèi)溫度的細(xì)微波動,確保測量數(shù)據(jù)的實(shí)時性。長期使用過程中,其抗干擾能力強(qiáng),不受電磁場、灰塵等常見室內(nèi)環(huán)境因素的顯著影響,保證測量精度持久穩(wěn)定。此外,它還具備良好的耐腐蝕性能,可適應(yīng)室內(nèi)不同濕度、化學(xué)物質(zhì)濃度等環(huán)境條件,使用壽命長,維護(hù)成本低,是室內(nèi)溫度測量的理想選擇。
English Introduction
The WREK-440 dual-element platinum resistance thermometer is a high-precision temperature measurement component specifically designed for indoor environments. It is made of high-quality platinum material, which ensures good stability and repeatability. Within the wide temperature range of -200℃ to 850℃, it can accurately and stably output resistance value signals that are linearly related to temperature. It meets the temperature monitoring needs of various indoor locations, such as laboratories, temperature-controlled warehouses, and clean rooms, providing a reliable basis for environmental control and temperature management.
The thermometer features a compact structure with a dual-element design, which provides two independent measurement signals. This redundancy enhances the reliability and safety of the measurement. In terms of installation, it is equipped with interfaces that are compatible with multiple installation methods. Whether it is mounted on walls, pipes, or other structures, it can be easily and securely installed without the need for complex tools or techniques.
In terms of performance, it responds quickly to temperature changes, allowing it to capture even the slightest fluctuations in indoor temperature and ensure the real-time nature of the measurement data. Over long-term use, it has strong resistance to interference and is not significantly affected by common indoor environmental factors such as electromagnetic fields and dust, ensuring the accuracy of the measurement remains stable. Additionally, it has good corrosion resistance, allowing it to adapt to different indoor environmental conditions, such as varying humidity levels and chemical concentrations. It has a long service life and low maintenance costs, making it an ideal choice for indoor temperature measurement.
