Hydrostatic level transmitter LFT3000

for oilfor waterfor liquids

Product overview
LFT3000 submersible liquid level transmitter uses a high-performance pressure sensor as the measuring element to measure liquid depth and convert it into a standard output signal via a dedicated signal-conditioning circuit, establishing a linear correspondence between output signal and liquid depth. It measures level from the transmitter tip to the liquid surface when immersed and is suitable for water and liquid level measurement and control in oil, chemical, power, municipal water and hydrological applications.

Features

• Oil-filled diffusion silicon sensing core with high precision and high overload capacity.
• Corrosion- and wear-resistant construction compatible with a range of liquids.
• Built-in temperature compensation; optional Modbus-485 (RS-485) communication for intelligent models.
• Removable stainless-steel top cap protects sensing diaphragm and allows easy cleaning.
• Double-layer waterproof top sensor structure for improved sealing; enclosure rated IP68 for continuous submersion.
