From "Pressure Conductor" to "Cable"
The electronic differential pressure level transmitter system consists of two high-precision pressure sensors (mounted at the top and bottom of the tank, respectively) and an electronic computing unit. The two sensors are connected by a single, ordinary electrical signal cable, completely replacing the complex oil-filled capillary tube.
The "master transmitter" reads the pressure signal from the "slave transmitter" in real time and calculates the differential pressure value at high speed using its built-in microprocessor, thereby accurately converting it into liquid level, volume, or mass. This "electronic" architecture fundamentally eliminates the risks of temperature drift and capillary leakage, allowing measurement to return to its essence.
Key Advantages
1. Ultra-high precision, full temperature range assurance
The new product is equipped with a high-sensitivity MEMS single-crystal silicon sensor or a high-performance ceramic sensor, ensuring ultra-high measurement accuracy and long-term stability. Even under conditions of drastic temperature changes, the elimination of the susceptible capillary effectively minimizes the impact of temperature on measurements.
2. Say goodbye to capillary, extremely simple installation and maintenance
For storage tanks tens of meters high, the length limitations and liquid column collapse risks of traditional capillary tubes have posed selection challenges. The new product only requires two small-size process connections at the top and bottom of the tank (starting from G½), enabling easy installation. This not only significantly reduces procurement and installation costs but also means that future maintenance will not require replacing the entire capillary tube; only the faulty sensor needs to be replaced, greatly reducing spare parts inventory and downtime.
3. Intelligent Connectivity, Leading the Digital Future
Adapting to the needs of Industry 4.0, the new product can be equipped with Bluetooth communication, enabling on-site commissioning and fault diagnosis via smartphone or tablet, eliminating the need for frequent trips between the tank top and bottom, significantly improving commissioning and maintenance efficiency. Simultaneously, its powerful self-diagnostic function can monitor sensor, circuit, and process anomalies in real time, enabling predictive maintenance and preventing problems before they occur.
Wide Range of Applications
Adaptability: Whether it's the harsh corrosive media of the chemical industry, the stringent hygiene requirements of the food and pharmaceutical industries, or the high-temperature, high-pressure steam environments of the power industry, YIGEQI new products can handle them all with ease. Especially for applications requiring high-precision inventory management, such as liquefied gas storage tanks, reaction vessels, and beer fermentation tanks, it is an ideal replacement for traditional differential pressure or radar systems.
