- AO952 monocrystalline silicon diaphragm pressure transmitter
measuring principle
The product uses the diffusion silicon sensor for differential pressure measurement, which is specially used for tapwater and sewade reatment titer tank detecion of head oss, it can measure the diterence between two noints oliquid level.
The head loss meter can be combined with the AOB instrument to form a head controller. The two processconnection heads of the transmitter are connected to the pressure point at the pool surface and the pressure poinbehind the filter material, as shown in the figure on the right below. This allows you to obtain the head change beforeand after the filter layer, and accurately measure the state of the fiter layer based on this parameter.main features
Range: 0~20KPa-70KPa;
accuracy :+0.2%FS;
High precision, good stability;Good seismic resistance, no mechanical moving parts;
Dual overload protection;
Shell material: aluminum (conventional), stainless steelapplication scenarios
It is suitable for pressure measurement in industrial field. According to thetemperature, pressure,corrosiveness,explosion-proof requirements,safety
requirements, measurement range and other working conditions of each type of
medium, various types of products are selected.
