The intelligent monocrystalline silicon remote level transmitter utilizes advanced MEMS technology from Germany to achieve high accuracy and stability under high overpressure. It features a unique double-beam suspended design and is embedded with a German signal processing module. This transmitter accurately measures differential pressure and converts it into a 4~20mA DC output signal. It can be operated locally using three buttons or remotely via a universal manual operator, configuration software, or smartphone app, allowing for display and configuration without affecting the output signal.
1. High Accuracy: The differential pressure transmitter can achieve high accuracy measurements within the range of -4 to 4MPa. The standard calibration range reference accuracy is ±0.2%.
2. Excellent Environmental Adaptability: Equipped with intelligent static pressure compensation and temperature compensation, the transmitter is protected from the effects of temperature, static pressure, and overpressure, minimizing comprehensive measurement errors on-site.
3. Outstanding Operational and User Convenience: Features a 5-digit LCD display with backlighting.
4. Offers various display functions (refer to selection notes)
5. Integrated three-button quick operation for on-site adjustments.
6. Available in various corrosion-resistant materials.
7. Comprehensive self-diagnostic functionality.
1. Oil/Petrochemical/Chemical Industry: Paired with throttling devices for precise flow measurement and control. Accurately measures pipeline and storage tank pressure and liquid level.
2. Electricity/Urban Gas/Others: Requires high stability and precision for pressure, flow, and level measurements.
3. Pulp and Paper Industry: For pressure, flow, and level measurements in environments needing resistance to chemical and corrosive liquids.
4. Steel/Non-ferrous Metals/Ceramics: Used for furnace pressure and vacuum measurements, demanding high stability and precision.
5. Mechanical Equipment/Shipbuilding: Utilized in settings where stable measurements of pressure, flow, and liquid level are critical under strictly controlled conditions.
