Submersible Chemical Level Sensor with PTFE Probe working principle
Like other hydrostatic pressure level sensors, our Submersible Chemical Level Sensor with PTFE Probe uses the hydrostatic pressure method to measure.
When the liquid level transmitter is put into a certain depth of the liquid to be measured, the pressure on the liquid surface of the sensor is: P=p.g.H+P0
In the formula:
P: pressure on the liquid surface of the sensor, unit: Pa
p: Density of the liquid to be measured, unit: kg/m3
g: local gravity acceleration, unit: m/s2
P0: Atmospheric pressure on the liquid surface, Unit: Pa
H: Depth of the sensor into the liquid, unit: m
At the same time, the atmospheric pressure P0 on the liquid surface is introduced into the back pressure chamber of the sensor through the air guide cable to offset the P on the liquid surface of the sensor. Let the pressure measured by the sensor be: P=p.g.H
Obviously, by measuring the pressure P, the liquid level depth H can be obtained. The pressure signal sensed by the sensor is converted and amplified by the circuit, and is output as a standard signal after compensation.
More Featured Level Sensors
The input part of the Chemical level sensor with PTFE probe is made of PTFE material, which is especially suitable for measuring corrosive high-temperature liquids. The sensor and signal processing circuit are designed inside the junction box. When the PTFE gas collector is inserted, it is necessary to measure the inside of the liquid and collect the pressure signal.
The liquid level pressure signal collected from the gas in the PTFE gas collecting barrel transmits the pressure to the sensor through the PTFE capillary. This avoids direct contact between the sensor and the measured medium. It is suitable for highly corrosive situations and other occasions. It effectively solves the problem of Difficulties in level measurement of corrosive liquids and sewage.
We at Sino-Inst supply various level sensors, in addition to Chemical level sensors with PTFE probe, there are also hydrostatic level transmitters, ultrasonic level meters, radar level meters, magnetostrictive level transmitters, etc. If you need to purchase a Chemical level sensor or have related technical questions, please feel free to contact us!
