The CYYZ203CY micro melt pressure transmitter adopts a glass micro melt core body, which is an integrated stainless steel structure in contact with the measuring medium. The product has no sealing parts or welds inside, fundamentally eliminating the hidden danger of measuring medium leakage. This feature is applicable to the measurement of hazardous media such as hydrogen and oxygen. This structure determines its high impact resistance, so it is also suitable for measuring transient high impact media. It also has a variety of explosion-proof function options, including intrinsically safe, dust intrinsically safe, explosion-proof, and explosion-proof dust types. It can also choose the HART protocol communication, which is cost-effective. It also has the advantages of diverse output signals and wide range, making it easy to match different working conditions on site.
