HHGP type differential pressure transmitter produced by our company is anew-pattern transmitter through bringing in foreign advanced technology and equipment. The key raw materials, components and parts are all imported. The whole machine is strictly assembled and tested. The design principle of our product is advanced; the types are multiple; and the installment and use are simple and convenient. Because the appearance completely blends the structure merits of currently the most popular and widely used two types of transmitters (Rosemount3051 and YOKOGAWA EJA)at home, it gives the users a completely new feeling. Meanwhile in terms of the installment it can be replaced with traditional 1151,CECC, etc. series of products, and has strong versatility and capability of replacement. In order to adapt the increasing improvement and development of domestic automation standard the series of products have exquisite design; furthermore they have the intelligentized function of HART site mainline protocol.
