The HQB-3000-LP Intelligent Level Transmitter is a high-precision, highly stable pressure measurement product independently designed and manufactured by our company. It features an imported monocrystalline silicon sensor chip and a differential pressure dual-diaphragm structure, combined with a dedicated digital circuit. Through signal amplification, linearity correction, anti-interference processing, surge protection, and other signal processing technologies, it provides an integrated solution with standard industrial signal output. The transmitter supports BLE 5.0, allowing users to connect directly to the device via a smartphone app to view and modify parameters. It is primarily used for liquid level measurement.
