Negative pressure transmitter is a new type of negative pressure transmitter, (gauge pressure) to measure the minimum pressure of 0.6KPa. (Can be migrated to negative pressure transmitter), the key raw materials, components and parts are imported, the whole machine after rigorous assembly and testing, with advanced design principles, a complete range of specifications, easy to install and use and so on. Negative pressure transmitter appearance of the integration of Rosemount 3051 and Yokogawa EJA structural advantages, but also a direct replacement for the traditional 1151, CECC series of negative pressure transmitter, has a strong generality and substitution ability. Negative pressure transmitter in addition to small and exquisite design, at the same time with HART field bus protocol intelligent function. Excellent measurement performance for pressure, differential pressure, level, flow measurement, widely used in a variety of industrial automation environments, involving petroleum pipelines, water conservancy and hydropower, railroad transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipeline air supply, boiler negative pressure, and many other industries!
Negative pressure transmitter working principle
When the pressure of the medium directly on the sensor diaphragm, so that the diaphragm produces with the medium pressure proportional to the micro-displacement, so that the sensor's resistance changes, and the electronic circuit to detect this change, and convert the output of a standard signal corresponding to this pressure.
