Capacitance pressure transmitter
ZW1151GP seriesCapacitance pressure transmitterIs the introduction of foreign advanced technology and equipment production of new type of transducer, the key raw materials, components and parts are imported, the whole machine after assembled and tested strictly, this product has the advanced design principle, the variety specification is complete, installation convenient use, etc.Due to the appearance on the total integration of the current domestic zui is popular, is suitable for the continuous improvement of the domestic automation level and development.
Second, the working principle:
ZW1151GP series capacitance pressure transmitter process pressure by both sides or one side of the isolation diaphragm, pouring the liquid to the center of the delta chamber to measure the diaphragm.Center diaphragm is a tensioning of elastic element, it is the effect on the pressure difference on both sides of the deformation displacement, the displacement is proportional to the differential pressure, zui large displacement is about 0.1 mm, the displacement of the change in capacitance differential capacitance is formed on the plate, by electronic circuit to convert the differential capacitance of the two wire 4 ~ 20 madc signal output.
Applications:
ZW1151GP series capacitance pressure transmitter is mainly used for measuring the pressure of gas, liquid and steam, and then convert them into 4-20 ma. DC signal output.It can measure the exhaust system, distillation tower, evaporator and absolute pressure of crystallizer, etc.Widely used in petroleum, chemical, electric power, papermaking, food, and municipal industries such as whole series of differential pressure, pressure, absolute pressure measurement.
