Micro soil temperature sensor and transmitter
1、 Product Introduction
Due tothe requirements for the measured flow field and placement position, it isnecessary to measure the temperature in situ and reproduce the temperaturechange law of the pulsating flow field without interfering with the flow fieldstate. There are often strict requirements for the miniaturization of theexternal dimensions of the sensor. The HC-28 micro temperature sensor isdesigned for the above working conditions. This series of products uses micromachined platinum thermistor PT100/PT1000 as the core component, stainlesssteel structure, high-precision integrated electronic components, and usesinternational advanced miniaturization production and packaging technology toexquisitely package the sensor chip and circuit board. The product has a small volume,compact structure, light weight, strong durability, and excellent measurementaccuracy, reliability, and stability. This series of products is particularlysuitable for civil engineering, geotechnical mechanics, and shrinkage. Manyresearch fields and on-site applications such as model testing; This product issealed with glue and can be soaked in water for use, completely waterproof.
