ZZC
Measurement is accurate and reliable
The sensor adopts a number of excellent performance technology (ReflexTM sensor safety diagnosis, CO2 and CH4 infrared sensing technology), with high accuracy, good stability, long life and other characteristics.
The n display is clear and intuitive
Using LCD large LCD screen, gas concentration number and bar chart display at the same time, and rich status icon display, multi-color backlight.
Operation of n is simple and quick
Full function site open cover non-intrusive operation.The magnetic rod is used to adjust the instrument on site.
The n-case is strong and durable
Aluminum alloy or stainless steel shell, strong corrosion resistance.
Function of n is rich and practical
The same shape structure is suitable for a variety of sensors, low purchase and operation cost, long sensor life, three relays output and two inlet line entrance can be expanded to install the local alarm, can set the maintenance plan, with fault diagnosis function.
The n-explosion-proof certification is complete
Suitable for dangerous places in zone 1 and 2 under various industrial and mining conditions, with several international mainstream institutions certification: GB, CCCF, KTL, ATEX, UL, CSA, IEC.
n Multiple signal outputs
1) Three-wire system 4-20mA industrial standard current signal connection mode (Source or Sink optional), can be connected to various gas alarm controllers, or PLC, DCS, SCADA and other systems.
2) Excessive range transmission and suppression (the user can set) and fault occurrence, to facilitate the system collection and processing of different current signals.
3) The three programmable relay output and Modbus RTU bus signal output are optional for various application requirements.
n Easy to install
Professional design of the general installation support, optional remote installation, make the instrument site installation convenient and fast.
n Easy maintenance
The sensor and transmitter adopt modular design, each module components are all plug and plug connection, it is easy to replace the components on site.
