Products Shenzhen Oriental Million and instrumentation company produced PT311L1 hydrostatic level transmitter is the use of hydrostatic water level or level measurement principle is an important application of the pressure sensor. Using micro-machining technology to produce high-sensitivity silicon pressure sensitive element is the heart of the resistance level sensor, complemented by a dedicated cable with ventilation ducts and a special water sealing technology, both to ensure the water seal immersion sensor, but also makes Reference pressure chamber communicates with the ambient air pressure, to obtain accurate results and excellent stability. PT311L1 level transmitter adopts the international advanced level of dry ceramic capacitive sensor with temperature compensation or isolated diffused silicon diaphragm pressure sensor, as the sensing element, which greatly improves the performance of the product. Widely used in petroleum, chemical, power plants, urban water supply and drainage, hydrology and water exploration in areas such as liquid level measurement and control.
