液位傳感器如何運用在制藥企業?

液位傳感器運用十分廣泛,特別是在制藥行業的運用尤為重要。液位檢測和監控在醫藥行業的生成中扮演著重要的角色,液位監控直接影響到產品的質量,甚至關系到生產過程能否順利進行。同時,液位檢測設備作為重要的計量器具,是生產過程中安全的重要保證要素之一。合格的液位檢測設備、過硬的液位檢測技術,不僅為制藥企業的原料輔佐、半成品和成品質量保駕起航。因此為了保證產品質量的一致,只有科學地選擇液位檢測技術,才能保證檢測結果的可靠性,穩定性。

液位計就是測量罐體或箱體里液位的高度,顯示里面的液位的高度,液位的用途非常廣泛,液位有包括液位信號器和連續液位測量兩種。液位信號器是對幾個固定位置的液位進行測量,用于液位的上、下限報警等。連續液位測量是對液位連續地進行測量,被廣泛應用石油、化工、食品加工、制藥行業等。

對于制藥企業常用的幾種液位檢測技術主要采用壓力法、浮力法、電學法、超聲波法、雷達法音叉振動法等等,然而在制藥企業中,合成生產及污水處理中使用的強酸、強堿原料均為強腐蝕性物體,其儲罐及水槽的液位檢測應該選用非接觸式液位計。目前隨著制藥過程自動化的實現,部分制藥廠家使用光電液位傳感器來控制液位。依據光電液位傳感器利用液體導電的性能來監測液位高低。液位一旦觸及對應的極棒便產生開關信號,信號經處理后用于控制液位。其實液位開關結構簡單,可測量不同液位,適用于不要求連續顯示具體液位的場合。

  Liquid level sensors are widely used, especially in the pharmaceutical industry. Liquid level detection and monitoring plays an important role in the generation of the pharmaceutical industry. Liquid level monitoring has a direct impact on the quality of products, and even related to the smooth progress of the production process. At the same time, as an important measuring instrument, liquid level detection equipment is one of the important factors to ensure the safety in the production process. Qualified liquid level detection equipment, excellent liquid level detection technology, not only for pharmaceutical enterprises to assist raw materials, semi-finished products and quality assurance set sail. Therefore, in order to ensure the consistency of product quality, only the scientific selection of liquid level detection technology can ensure the reliability and stability of the test results.

The liquid level meter is to measure the height of the liquid level in the tank or the tank, showing the height of the liquid level inside. The liquid level has a wide range of uses, including the liquid level signal and continuous liquid level measurement. The liquid level signal is used to measure the liquid level in several fixed positions and alarm the upper and lower limits of the liquid level. Continuous liquid level measurement is a continuous measurement of liquid level, which is widely used in petroleum, chemical industry, food processing, pharmaceutical industry and so on.

Pressure method, buoyancy method, electrical method, ultrasonic method, radar tuning fork vibration method and so on are mainly used for several liquid level detection techniques in pharmaceutical enterprises. However, in pharmaceutical enterprises, the strong acid and alkali raw materials used in synthetic production and sewage treatment are strongly corrosive objects, and the liquid level detection of tanks and tanks should be carried out. The non-contact liquid level gauge is selected. At present, with the realization of pharmaceutical process automation, some pharmaceutical manufacturers use photoelectric liquid level sensor to control the liquid level. According to the photoelectric liquid level sensor, the liquid level is monitored by the performance of liquid conduction. Once the liquid level reaches the corresponding pole, a switch signal is generated, and the signal is processed to control the liquid level. In fact, the liquid level switch has simple structure and can be used to measure different liquid levels. It is suitable for occasions where the specific liquid level is not required to be displayed continuously.
