NFDP2001 Smart Differential Pressure Transmitter
The NFDP2001 smart differential pressure transmitter measures differential pressure, flow, level, density and pressure of liquids, gases or steam. It provides a 4-20 mA DC output with remote configuration and monitoring capability.
Product Overview
▅ Product Features
1. Using monocrystalline silicon piezoresistive technology, the performance is stable and the accuracy can reach ±0.075%FS;
2. The maximum range ratio is 100:1, and the measurement range can be adjusted flexibly;
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 and can reach ±0.2%SPAN/5 year
▅ Applicable scenarios
Oil and gas industry, food processing, pulp and paper, electric power energy, chemical industry, marine equipment.
