KPT1000-DP Monocrystalline Silicon Intelligent Differential
Pressure Transmitter
1.Introduction
The KPT1000-DP single crystal silicon differential pressure transmitter uses a single crystal silicon sensor chip made of advanced German MEMS technology, a double diaphragm structure, and exquisite production technology to achieve high precision and ultra-high stability of the product. The embedded intelligent signal processing module achieves the perfect combination of pressure and temperature compensation, providing reliable measurement accuracy and excellent long-term stability under a wide range of static pressure and temperature changes.
The KPT1000-DP single crystal silicon differential pressure transmitter can be used to measure the liquid level, density, and pressure of liquid, gas, or steam, and convert it into a 4-20mA DC (superimposed HART communication) current signal output;
Remote and local parameter setting function configuration is realized through Hart or RS485 communication and panel buttons.
2.Features
- High precision level: German high-precision single crystal silicon sensor chip, accuracy ≤ ±0.05%.
- Strong load resistance: double overload protection diaphragm design, single overpressure can reach 42MPa.
- Excellent environmental adaptability: intelligent static pressure compensation and temperature compensation eliminate the influence of temperature, static pressure and overload on the transmitter, and minimize the comprehensive test error on site.
- Excellent long-term stability: stability can be maintained at 0.1FS%/3 years.
- Flexible remote assistance debugging function: remote and local parameter setting function configuration is realized through Hart or RS485 communication and panel buttons.
3.Applications
- Petroleum/Chemical/Fossil: Matched with throttling devices, it provides accurate flow measurement of pipeline and tank pressure and liquid level.
- Electricity/City Gas: Places that require high stability and high precision pressure, flow, and liquid level measurement.
- Pulp/Papermaking: Used for furnace pressure, negative pressure measurement and other places that require high stability and high precision measurement.
- Steel/Nonferrous Metals/Ceramics: Used for pressure, flow, and liquid level measurement places that require chemical resistance and corrosion resistance.
- Mechanical Equipment/Shipbuilding: Used for places that require stable measurement under strict control of pressure, flow, liquid level and other indicators.
