NFDP2001-LT Smart Differential Pressure Level Transmitter
The NFDP2001-LT smart differential pressure level transmitter is mainly used for liquid level measurement. It converts the measured pressure signal into a 4-20 mA DC output and supports remote configuration and monitoring.
Product Overview
▅ Product Features
1. Using monocrystalline silicon piezoresistive technology, the performance is stable and the accuracy can reach ±0.075% FS + the influence of the diaphragm system;
2. The high overload protection diaphragm realizes the large pressure overload protection function;
3. The use of high-performance EMC protection circuit modules effectively reduces the impact of electromagnetic disturbance on the output of the product;
4. The stability is strong up to ±0.2% SPAN/5 year
▅ Applicable scenarios
Oil and gas industry, food processing, pulp and paper, power energy, chemical industry, marine equipment.
