The PL-type PT1000 temperature sensor comes with a thermal installation sleeve, supporting sensor replacement under pressure, allowing maintenance without draining the pipeline, significantly improving the maintenance efficiency of large-diameter pipeline networks. The product's accuracy class complies with the IEC 751 standard, offering high pairing precision, and is especially suitable for applications with small temperature difference measurements in heat meters.

Our company designed and manufactured a heat meter temperature sensor production line independently in 2010, with an annual production volume of 500,000 pairs. The heat meter temperature sensor consists of five components: temperature sensing element, thermal conductor, protective sheath, mounting thread, and lead wires. It generally uses Pt1000, tolerance level B, pairing accuracy less than 0.06℃. It stands out with high accuracy, fast thermal response, and stable performance.
PL type pt1000 rtd: Suitable for use in the main hot water pipe of communities. The heat meter comes with a protective tube equipped with G1/2 fixed thread, thus when it is time to replace, the user only needs to unfix the inner temperature sensor and slide it out to replace it, there is no need to drain the main pipe. It is suitable for DN65~DN250 hot water pipes.
