NCS-PT105Ⅱ Series Smart Pressure Transmitter
NCS-PT105Ⅱ series Smart Pressure Transmitter with advanced, mature, reliable 3151 capacitance sensors has been 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..
According to the type of measurable pressure:
Model | Pressure type |
NCS-PT105ⅡSG | Gauge pressure transmitter |
NCS-PT105ⅡSA | Absolute pressure transmitter |
NCS-PT105ⅡSD | Differential pressure transmitter |
NCS-PT105ⅡSH | Differential pressure transmitter for high static pressure |
According to the protocol:
Model | Communication Protocol type |
NCS-PT105ⅡH | HART |
NCS-PT105ⅡF | FF H1 |
NCS-PT105ⅡP | PROFIBUS PA |
As a transitional communication protocol in fuildbus, HART protocol achieves digital transmission on the existing analog transmission lines, and is compatible with existing analog signal control system. Either FF H1or PROFIBUS PA is a new generation of digital communication protocol, used in field connection, and linking field devices. International Standard IEC61158-2 is used in physical layer. Therefore, either FF H1or PROFIBUS PA is fieldbus actually.
As following, Smart Transmitter with HART protocol is named as HART Smart Transmitter; Smart Transmitter with FF H1 protocol is named as FF Smart Transmitter; Smart Transmitter with PROFIBUS PA protocol is named as PA Smart Transmitter, All of these (Transmitters with the three types of fieldbus protocol) are named as Smart Pressure Transmitters or Smart Transmitters. In addition, HART Smart Transmitter has passed explosion-proof certification from National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation (NEPSI).
