Submersible pressure transmitter is a hydrostatic pressure sensor. Because it can be put into water, the liquid level can be calculated by measuring the underwater static pressure, so it is also called throw-in water level transmitter / level transmitter / level sensor / level gauge. Submersible pressure transducer is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. Use advanced isolated diffused silicon sensitive element or ceramic capacitor pressure sensitive sensor. Convert static pressure into electrical signal. After temperature compensation and linear correction. Converted into standard electrical signals (such as 4 ~ 20mA, etc.). It can also equipped with digital display head or panel alarm indicator to read real-time display.
submersible pressure transmitter for level measurement
The submersible static pressure liquid level transmitter is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid, and uses the piezoresistive effect of diffused silicon or ceramic sensitive elements to convert the static pressure into an electrical signal. After temperature compensation and linear correction, it is converted into 4-20mADC standard current signal output.
The relationship between liquid pressure and depth:
P=P0+rh
Pressure at P-liquid depth h
P0-pressure at atmospheric pressure
H-liquid depth
Y-liquid density
what is the submersible pressure transmitter max depth?
For ordinary liquid level measurement, the range of 0m ~ 300m can already meet the needs of users. For deep well water level measurement, we can use our Deep Well Water Level Sensor, up to 1000 meters. Also supports customer customization.
What is the submersible level transmitter lighting protection function?
Lightning protection type Submersible pressure transducer is an outdoor type liquid level transmitter used in industrial fields that is free from frequent high-voltage overvoltage during lightning strikes and limits freewheel time and freewheeling value.
Why choose 4-20ma signal submersible pressure transmitter ?
The reason for using a 4-20ma current signal is that it is less susceptible to interference. And the internal resistance of the current source is infinite. The wire resistance is connected in series in the loop without affecting the accuracy. And it can be transmitted over ordinary twisted pairs for hundreds of meters.
How to install the submersible level transmitter ?
Submersible pressure pressure level transducers are designed for measuring ground and surface water pressure, temperature and water level.
The submersible pressure transducer is suitable for a wide range applications of Urban water supply and drainage,Sewage treatment, water tanks,Oil tank oil tanks, hydrogeology, reservoirs, rivers and oceans and other fields.
a. Submersible level sensor installation example in still water (deep well, pool, liquid tank)
b. Submersible pressure level transmitter installation example in moving water
Method 1: When the medium fluctuates greatly, a steel pipe is inserted into the water channel, and the internal
strength is about 4.5, and a small number of holes are formed at different heights on the opposite side of the
water flow direction, so that the flowing water enters the pipe.
Method 2: When the medium fluctuates greatly, it is also possible to filter the sediment by adding a damping
device and eliminate the adverse effects of dynamic pressure and waves to ensure measurement accuracy.
