NFDP2001-LP Smart Remote-Seal Differential Pressure Transmitter
The NFDP2001-LP smart remote-seal differential pressure transmitter is used for level, density, pressure and flow measurement of liquids, gases or steam where remote diaphragm seals are required for harsh or special process conditions.
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;
▅ Applicable scenarios
Oil and gas industry, food processing, pulp and paper, electric power energy, chemical industry, marine equipment.
