What is a submersible level transmitter and where is it used?
A submersible level transmitter is a device designed for continuous liquid level measurement while fully immersed in the medium. It is widely used in sewage, wastewater, deep wells, and industrial tanks.
How does a level transmitter measure liquid level?
A level transmitter uses a pressure sensing element (piezoresistive sensor) to detect hydrostatic pressure, which is proportional to the liquid height, and converts it into a standard output signal.
What makes this level transmitter suitable for sewage applications?
This model features a steel cage protection design, anti-corrosion materials, and IP68 sealing, allowing reliable operation in high solids, sludge, and debris environments.
What is the typical accuracy of an industrial level transmitter?
Industrial level transmitters typically offer ±0.5% FS accuracy, with higher precision options up to ±0.25% FS, depending on configuration.
Can this level transmitter be used in hazardous areas?
Yes, it is designed with explosion-proof certification (Ex d IIC T6 / Ex ia IIC T6), making it suitable for hazardous industrial environments.
What output signals are available for integration?
This level transmitter supports 4–20mA, voltage outputs, and RS485 Modbus RTU, enabling easy integration with PLC and SCADA systems.
