1.use high quality cable with air duct; can choose field display;
2.two kinds of sensors are optional, various application conditions, ceramic sensor
with big hole design, anti-blocking, anti-corrosion.
3.use imported silicon piezoresistive sensor with high accuracy and good stability;
3.directly put into the measured liquid, simple installation.
Application Case
HCDB-30 liquid level meter , Simple type, silicon piezoresistive sensor, without head, not directly with field display.The max measuring range can reach 350m ( can customized if beyond this range) . The output signal has two options : (4-20) mA or RS45 standard protocol .
Principle
The input level gauge is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. The pressure signal is converted into electrical signal by the pressure sensor, and then converted into standard current signal or digital signal after temperature compensation and linear calibration. When the liquid level transmitter is put into a certain depth in the measured liquid, the pressure formula of the sensor diaphragm is as follows:
Ρ = ρ * g * H + Po
in the formula :
P → Pressure on the sensor diaphragm
ρ → The density of the liquid being measured
g → Local gravitational acceleration
H → The depth of where level sensor is in the liquid
P0 →Liquid surface atmosphere pressure
Use meter pressure sensor , connect the cavity of the level gauge witho the atmospheric pressure through the air tube to offset the P0, so we can get P = ρ * g * H, Obviously, the liquid level height can be obtained by converting the measured pressure value. That is: H = P/(ρ * g)
