| The stability and reliability of a pressure transmitter plays a critical role in industrial process control. As a testing and calibrating device, pressure calibrator is absolutely necessary in this process. The traditional calibrator for pressure sensor and transmitter is huge in volume with complicated procedure, which can not satisfy the field need for its inconvenience. In recent years, some foreign companies have developed new portable pressure calibrators, and there is still a wide gap between pressure calibrators made at home and abroad both in quality and in accuracy. Therefore, even if the price of foreign products is much higher than that made domestically, the foreign products is still highly competitive and covers most part of market share. It is an urgent task for us to develop our own firm, durable and easy- to- work portable pressure calibrator to occupy our domestic market.A new portable pressure calibrator is developed which based on Si-diffused pressure sensor and processor of high accuracy. By adopting separate structure of pressure generation bump and mainframe, it can be used for calibration and maintenance for pressure gauge, pressure sensor, transmitter, level meter and other pressure instrument. The advanced technology and unique creativity of this product contribute its high quality, which can compete with foreign products.The new developed pressure calibrator can still work outside laboratory and working area to assure the validity of industrial control system by the greatest extent. The launch of the portable pressure calibrator greatly alleviates labor intensity of operators and greatly improves their working efficiency and preciseness.Based on good command of performance and perfect appearance and its unique application background, the product has competitive price to ensure the successful market prospect. |
