Plastic submersible 4-20mA liquid level sensors are a type of hydrostatic level sensor that uses a pressure-sensing element to measure the hydrostatic pressure of the liquid. The sensor is typically housed in a durable plastic casing that is resistant to a wide range of chemicals. The 4-20mA current output signal is a standard industrial signal that can be easily integrated with various process control and monitoring systems.
Advantages
- Chemical Resistance: The plastic casing material is selected for its compatibility with a wide range of chemicals, making these sensors suitable for use in aggressive environments.
- Submersible Design: The sensors can be fully submerged in the liquid, allowing for continuous level measurement even in turbulent conditions.
- 4-20mA Output: The 4-20mA current output signal is a robust and reliable signal that is less susceptible to noise and interference than voltage signals.
- Cost-Effective: Plastic submersible sensors offer a cost-effective solution compared to other types of level sensors, such as ultrasonic or radar sensors.
Applications
- Chemical Processing: Monitoring the level of acids, alkalis, and other corrosive chemicals in storage tanks, mixing vessels, and process lines.
- Water and Wastewater Treatment: Measuring the level of water or wastewater in tanks, sumps, and clarifiers.
- Pharmaceutical Industry: Measuring the level of liquids in mixing tanks, reactors, and storage vessels.
Selection Considerations
- Chemical Compatibility: Ensure the sensor’s casing material is compatible with the specific chemicals being measured.
- Measurement Range: Select a sensor with a measurement range that is appropriate for the application.
- Accuracy: Consider the required accuracy of the level measurement.
- Installation Requirements: Consider the installation requirements, such as the mounting method and cable length.
Plastic submersible 4-20mA liquid level sensors are a versatile and reliable solution for a wide range of liquid level measurement applications.
