Novel pressure measurement device

The invention relates to the easy crystal gas phase pressure measurement technical field, more specifically a novel pressure measurement device which uses a stainless steel pressure pipe to transmit pressure, and prevents crystal substances from eroding a transmitter. The cylindrical shell center of a pressure transmitter inserting into a device is welded with a helical stainless steel pressure pipe, and transmitter oil is injected into a whole pressure pipe, thereby saving money and reducing maintenance costs. In order to achieve the purposes, the novel pressure measurement device comprises a pressure transmitter, a conduit, a flange and a plurality of valves; the central section of the flange is provided with a through hole, and the flange is fixedly connected to the conduit; the other end of the conduit is in connection with the pressure transmitter; the pressure pipe is provided with a stop valve. The novel pressure measurement device also comprises a helical pressure pipe and a cylindrical shell; the cen
