First, static pressure input level transmitter Product Description:

The BPY800 hydrostatic input type level transmitter was developed by introducing advanced advanced diffusion silicon pressure sensors and IC Sensors circuit technology. It uses the silicon etching process and silicon wafer superposition of two cutting-edge technologies in the world, which is a high The quality of static pressure level measurement instrument, won the title of high-tech products, widely used in petroleum, chemical, metallurgy, environmental protection, food, water conservancy, urban water supply, oil and other industries level measurement. The superior quality of the Huo-Fang Fangyuan BPY800 static pressure level transmitter meets the needs of China's industrial automation and measurement automation in some industries for high-precision liquid level detection instruments.

Second, static pressure level transmitter features:

1, good stability, high precision, high performance and price ratio

2, directly into the measured medium, the installation is very convenient

3, solid structure, no moving parts, high reliability, long service life

4. High-precision measurement can be made from water, oil, and high-viscosity pastes without being affected by bubbling, deposition, and electrical properties of the measured medium.

5, no material fatigue and wear, not sensitive to vibration, impact

6, with power inverting polarity protection and overload current limiting protection

Third, the static pressure input level transmitter works:

The principle of static pressure measurement

When the level transmitter is put into a certain depth in the tested liquid, the pressure of the sensor's flooding surface is P=pgH+Po.

P: Pressure on the sensor's flooding surface Unit: Pa

P: depth of liquid to be measured Unit: kg/m3

G: Local gravitational acceleration Unit: m/s2

P0: Atmospheric pressure on the liquid Unit: Pa

H: Depth of sensor input liquid Unit: m

At the same time, the air pressure cable is used to introduce the atmospheric pressure Po on the liquid surface into the back pressure chamber of the sensor to lower the P of the sensor liquid surface, so that the pressure measured by the sensor is: P=pgH. Obviously, by measuring the pressure P, The depth H of the liquid level can be obtained. The pressure signal sensed by the sensor is amplified by the circuit conversion and is compensated and output as a standard signal.

Note: This model should measure the level of the open container

Closed container is measured with a 1151DP or 1151LT differential pressure transmitter
