NFGP2002 Smart Gauge Pressure Transmitter
The NFGP2002 smart gauge pressure transmitter uses monocrystalline silicon piezoresistive sensing technology to measure the pressure, level or density of liquids, gases and steam. It outputs a 4-20 mA DC signal and supports remote configuration and monitoring through communication devices.
Product Overview
▅ Product Features
1. Using monocrystalline silicon piezoresistive technology, the performance is stable and the accuracy can reach ±0.075% FS;
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 years.
▅ Applicable scenarios
Oil and gas industry, food processing, pulp and paper, electric power energy, chemical industry, marine equipment.
