Wear-resistant RTD (PT100)

Brief Description

The WZPN-331 wear-resistantRTD (PT100) produced by Shanghai Automation is mainly used in the field whichmay cause heavy wear with low temperature medium (-200-450℃),like power plant circulating fluidized bed, cement and chemical plant etc. The WZPN-331 wear-resistant RTD(PT100) from our company is of international level with advanced technology,the special wear-resistant material guarantee its long-service life (1~2 years)without influence on measuring lag. Protection tube is wear-resistant,high-temperature oxidation resistant, as well as vulcanization-resistant,liquid iron powder resistant, limestone resistant, rush-resistant,vibration-resistant etc.
