      3151液位變送器是一種將壓力轉換成氣動(dòng)信號或電動(dòng)信號進(jìn)行控制和遠傳的設備。 它能將測壓元件傳感器感受到的氣體、液體等物理壓力參數轉變成標準的電信號(如4~20mADC等),以供給指示報警儀、記錄儀、調節器等二次儀表進(jìn)行測量、指示和過(guò)程調節。用于各種工業(yè)自控環(huán)境,涉及水利水電、鐵路交通、智能建筑、生產(chǎn)自控、航空航天、軍工、石化、油井、電力、船舶、機床、管道等眾多行業(yè)。

      當被測介質(zhì)(液體)的壓力作用于傳感器時(shí),壓力傳感器將壓力信號轉換成電信號。經(jīng)歸一化差分放大和輸出放大器放大,最后經(jīng)V/A電壓電流轉換器轉換成與被測介質(zhì)(液體)的液位壓力成線(xiàn)性對應關(guān)系的4~20mA標準電流輸出信號。

      When the pressure of the measured medium (liquid) acts on the sensor, the pressure sensor converts the pressure signal into an electrical signal. After being amplified by normalized differential amplifier and output amplifier, it is converted into 4 ~ 20mA standard current output signal which is linearly corresponding to the liquid level pressure of the measured medium (liquid) by V / a voltage current converter.

      3151自動(dòng)化0.1精度液位傳感器儀表是一種把非電量轉變的電信號的器件,而檢測儀表在模擬電路情況下,一般是包括傳感器、檢測點(diǎn)取樣設備及放大器(進(jìn)行抗干擾處理及信號傳輸),當然還有電源及現場(chǎng)顯示部分(可選擇),電信號一般分連續量、離散量?jì)煞N,實(shí)際上還可分成模擬量、開(kāi)關(guān)量、脈沖量等,模擬信號傳輸采用統一信號(4~20mADC等)。數字化過(guò)程中,檢測儀表變化比較大,經(jīng)過(guò)幾個(gè)階段,近來(lái)多采用ASIC專(zhuān)用集成電路,而且把傳感器和微處理器及網(wǎng)絡(luò )接口封裝在一個(gè)器件中,完成信息獲取、處理、傳輸、存貯等功能。在自動(dòng)化儀表中經(jīng)常把檢測儀稱(chēng)為變送器,如溫度變送器、壓力變送器等。

      3151 automatic 0.1 precision liquid level sensor instrument is a kind of device which transforms non electric quantity into electrical signal. In the case of analog circuit, the detection instrument generally includes sensor, sampling equipment and amplifier (for anti-interference processing and signal transmission), and of course, power supply and field display part (optional). The electrical signal is generally divided into continuous quantity and discrete quantity It can also be divided into analog quantity, switching value, pulse quantity, etc. the unified signal (4 ~ 20mADC, etc.) is adopted for analog signal transmission. In the process of digitization, the detection instrument changes greatly. After several stages, ASIC ASIC ASIC is widely used recently, and sensors, microprocessors and network interfaces are packaged in one device to complete information acquisition, processing, transmission, storage and other functions. In automatic instruments, the detector is often called transmitter, such as temperature transmitter, pressure transmitter, etc.

      在現代工業(yè)設備中,3151自動(dòng)化0.1精度液位傳感器儀表和檢測儀表是不可或缺的。從以下兩方面來(lái)看:傳統的工業(yè)設備如在其上增加了必要的傳感器,配備精密測量部件(附件),則其功能和精度可以提高,便于用戶(hù)操作和維護,安全等級也可以提高,設備可以增值;工業(yè)設備作為自動(dòng)化系統的控制對象或作為自動(dòng)化系統的一部分,必須能與自動(dòng)化系統的三部分(檢測、控制、執行)相兼容或提供接口,使之集成為一個(gè)有機的整體,無(wú)論是單機自動(dòng)化或作為大型自動(dòng)化裝置的一部分,都使該工業(yè)設備的用途擴大。綜上所述,作為工業(yè)設備本身增加傳感器和檢測儀表、測量?jì)x表或提供接口,是傳統設備更新?lián)Q代的必要條件。

      In modern industrial equipment, 3151 automatic 0.1 precision liquid level sensor and detection instrument are indispensable. From the following two aspects: if the traditional industrial equipment is added with necessary sensors and equipped with precision measurement components (accessories), its function and accuracy can be improved, which is convenient for users to operate and maintain, the safety level can also be improved, and the equipment can be added value; as the control object of the automation system or as a part of the automation system, the industrial equipment must be able to automatically and automatically The three parts (detection, control and execution) of the chemical system are compatible or provide interfaces, so that they can be integrated into an organic whole. Whether it is a single machine automation or a part of a large-scale automation device, the use of the industrial equipment will be expanded. To sum up, as an industrial equipment, adding sensors, measuring instruments or providing interfaces is a necessary condition for the upgrading of traditional equipment.

      在華恒儀表制造廠(chǎng)家看來(lái),具有比較高穩定性是作為3151系列儀表制造中很重要的生產(chǎn)基礎,立足于西安華恒儀表生產(chǎn)廠(chǎng)家的華恒儀表,以核心的電路板生產(chǎn)制造和金屬電容/擴散硅傳感器完全自主的能力,為廣大廠(chǎng)商提供特殊訂制,復雜工況專(zhuān)業(yè)設計,大宗客戶(hù)貼牌生產(chǎn)等一線(xiàn)式服務(wù).
