GENERAL
Smart differential pressure transmitter is a highly sophisticated and advanced device that has revolutionized the way pressure is measured and monitored in various industries. It is a highly reliable and accurate tool that helps industries to maintain efficiency and safety while optimizing their operations.
Â
Â
FEATURES
1.Widely used for measuring differential pressure (or pressure), level, density of liquid, gas or steam and convert the value of above into current signal output or digital protocol output.
2.The pressures are directly applied to the isolating diaphragm that provide isolation and resistance against process fluid corrosion.
3.Being microprocessor based, the electronic circuit is extremely versatile and accurate.
4.Combined with the sensor precision, it provides the high accuracy and range ability.
5.Transmitter performance is improved by continuous monitoring of the sensor temperature and corresponding corrections.
6.A local display permits easy reading and writing of data
