A New Type of High Temperature Remote Pressure Transmitter Description
Technical field:
This invention is a new type of high-temperature remote pressure transmitter, which can be applied to high-temperature dielectric corrosion resistance, high temperature 300 °C ~ 600 °C measurement, can be widely used in chemical, electric power, metallurgy, pharmaceutical and other fields.
Industry technology situation:
Currently, the pressure transmitters at home and abroad are composed of diaphragms, connecting flanges, stainless steel capillary tubes, pressure differential pressure transmitter bodies, and high-temperature filling fluids. However, in the measurement of high-temperature media, this filling solution is liable to have a high boiling point and poor fluidity in a high temperature medium environment, thereby affecting the capillary transmission speed. Causes the pressure value to appear sluggish. The expansion of the filling fluid causes damage to the diaphragm and cannot be repaired. It is difficult to use in a high-temperature medium measurement environment above 300°C.
Technological innovation:
In order to overcome the current remote transmission pressure in the current market, the differential pressure transmitter is difficult to use in high temperature environment, the maximum length of the capillary tube is 15 meters, and maintenance and maintenance are inconvenient. Specially invented a new type of high-temperature remote transmission pressure and differential pressure transmitter. This transmitter consists of two different connection areas. It uses high-temperature filling area combined with a high-temperature sensor and a high-temperature cable to achieve high-temperature filling at high temperatures. The liquid is in direct contact with the high-temperature medium, so that the high-temperature sensor is away from the high-temperature medium, so that the ultra-high-temperature remote transmission pressure and differential pressure transmitter can be used in high-temperature medium measurement above 300°C at the same time. The traditional remote transmission pressure and differential pressure are transmitted to the pressure and differential pressure transmitter body through the capillary-filled silicone oil to measure the pressure. The traditional disadvantage is that the capillary can not exceed 15 meters in length. Once the capillary oil leaks, This will lead to the entire transmitter measurement can not be achieved; maintenance needs to send back to the manufacturer re-welding filling, and this new type of high temperature remote pressure differential pressure transmitter also makes up for the traditional remote pressure, differential pressure transmitter Inadequate, in the measurement work encountered the damage of the transmitter can immediately notify the manufacturer to do a new set of high-temperature areas and high temperature sensor area debugging, users get the goods directly through the communication cable and pressure, differential pressure transmitter body Communication, which greatly saves time and maintenance costs.
