Cwb120 small temperature transmitter is a smaller and more compact temperature measurement sensor than cwb130. It is also made based on standardized PT100 or PT1000 temperature sensor elements and high performance special signal conditioning circuit. The temperature sensor adopts German high-quality temperature platinum resistor, combined with Zetian sensor mature production technology, the product performance is excellent, the maximum measurement temperature can reach 125 degrees. Cwb120 structure adopts laser welding and stainless steel structure, which has strong anti shock and anti-interference ability; it is beautiful, compact and solid, especially suitable for applications with limited installation space.
