Water Pipe Explosion Proof Pressure Transmitter
Water Pipe Explosion Proof Pressure Transmitter Description:
Water Pipe Explosion Proof Pressure Transmitter series smart pressure transmitter with advanced, mature, reliable Piezoresistive Silicon Sensors has been designed meticulously by combining advanced microprocessor technology and digital capacitance measurement techniques. Its LCD can display many physical parameters such as pressure, temperature, current. It can be realized zero adjustment, range settings and other features by key-press operation, and easy to on-site tests.
Water Pipe Explosion Proof Pressure Transmitter supports HART, FF H1, Profibus PA, Profibus DP protocol and can measure pressure, differential pressure, liquid level, flow, and other industrial parameters. It can be widely used in the petroleum, chemicals, electricity, and metallurgical industries, etc.
