Hydrostatic Pressure Transmitters is an instrument that measures the hydrostatic pressure or differential pressure exerted by a hydrostatic head.
Feel the measured pressure through the remote transmission device installed on the pipeline or container. The pressure is transmitted to the main body of the transmitter through the filling silicone oil (or other liquid) in the capillary tube. Then there is the delta chamber and the amplifier circuit board in the main body of the transmitter. Convert into 4-20mA DC signal output. It can communicate with a HART handheld communicator to set, monitor, or form an on-site monitoring system with the host computer.
What is Hydrostatic Pressure?
Hydrostatic pressure is the pressure generated by the weight of the liquid above the measurement point when the liquid is stationary. The height of the liquid column with uniform density is proportional to the hydrostatic pressure. As the weight of the fluid exerting downward force from above increases, the hydrostatic pressure increases in proportion to the depth measured from the surface.
If the fluid is inside the container, the depth of the object placed in the fluid can be measured.
Formula for calculating hydrostatic pressure as follows:
Phyd = h.ρ.g
Prel = h.ρ.g
Pabs = h.ρ.g + Patm
Phyd = Hydrostatic Pressure (Pa)
Prel = Relative Pressure (Pa)
Pabs = Absolute Pressure (Pa)
Patm = Atmospheric Pressure (Pa)
h = Liquid Height (m)
ρ = Liquid Density (kg/m3)
g = Local Gravity (m/s2)
The above calculation formula is also the working principle of hydrostatic liquid level sensor.
What is a dydrostatic pressure sensor?
The hydrostatic pressure sensor measures the hydrostatic pressure applied by the hydrostatic head. Output 4-20mA.
Use a hydrostatic pressure transmitter to measure the storage tank and pump inlet. And other applications where hydrostatic pressure is used to determine the liquid level.
What is a hydrostatic level sensor?
Hydrostatic Level Sensor measures the hydrostatic pressure by the submersible pressure sensor. The static pressure of the liquid is proportional to the height of the liquid. Then the static pressure was converted into an electrical signal. Convert to analog signal output or 4-20mADC. With digital display. For water level measurement, hydrostatic level sensor is a low cost type. Different types of measuring cells are used in level measurement based on the hydrostatic principle.
SenTec Hydrostatic Level Sensor design with Lightning protection, anti-corrosion, explosion-proof optional. IP68 is optional.
