The GUARDIAN series of Smart Pressure, Temperature and Multivariable Transmiters uses the most advance, mature, and reliable sensors to offer customer a perfect balance between exceptional performance and price. These transmiters were designed meticulously by combining advanced microprocessor technology and digital capacitance measurement technology. The powerful functions and high-speed computing capability of the microprocessor make it have excellent qualifications such as smart, high precision, high reliability, stable zero and so on. Its LCD can display many physical parameters (e.g. pressure, temperature, current and so on). It can realize the functions such as zero adjustment, range settings by key-press operation, and it is easy for field testing. NCS-PT105Ⅱ series Smart Pressure Transmitter supports HART, FF, and PA 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..
