4-20mA analog output for direct communication to DCS system or RS485 ModBus RTU output optiona.
Relay output for connecting external device
LCD display screen(LED display screen optional)
Advantage: Sensor module(block) design on -spot replacement s and automatically distinguish sensor fault and current display fault simultaneously.
When the sensor out of service or the sensor fails, the user can check and solve the problem by replacing spare modules,saving the time and cost.
The LCD display and LED display module can be interchanged, supporting swift hot swap,support plug and play functionality.
The sensor module and the connection interface in the detector have jack and plug prevent improper insertion.Just spin and press the plug gently,the plug can be inserted the jack.
The sensor module of the detector can be replaced by the same type module and the different gas sensor module,and different range sensor module. The detector can distinguish and operation itself.
Whatever the sensor module is chosen to replace the original one, there is no need to re-calibrate it. The detector automatically distinguishes the sensor module, reads the ex-factory calibration value and the related setting value and operates detecting when the self-inspection is done.
Password verification for repeat operation, avoid fault operations.
-40~+70 following compensation for accurate detecting.
Twp grade visual alarms on-site and Relay (connected with audible/visual alarms or drive exhaust device).
User-selectable alarm setpoint(s).

Specially design for solar-public electricity system, which is in exchange of the solar system, it has power switch where there is a shock by the battery or utility grid, and also the utility grid supply charging module. Its energy saving, and also ensures the power supply. It also has the same function of eprc.

Specifications: 12v, 12/24v, 5a, 10a, 15a

Use mcu and professional software as the control center to fulfill intelligent soc control, protection to overload, outside and insdie short circuit, reverse connection, thunder and lightining, pv panel reverse current, over charge and discharing etc, usd pwm high efficiency charging way and temperature compensation.

Industry level production standard, led indication on system condition.

NCS Series of Intelligent Transmitters are digital, intelligent, network-based, merged with advanced, reliable and stable sensor technology, to be designed as a new generation of Fieldbus Intelligent Transmitter.



NCS Series of Intelligent Transmitter have been designed with high precision and high reliability, high stability. The pressure, temperature, currents and other physical quantities are displayed on LCD module. Zero drift, range settings and many other functions, are realized by the magnetism bar operation. The interoperability between different systems and equipments are realized by the Equipment Description Document, which is compatible to a variety of device management software, and adapting to harsh electromagnetic environment. NCS Series of Intelligent Transmitter have been used in inflammable and explosive places according to Intrinsically Safety Design.

The Fieldbus Technology is used in NCS-TT105 Intelligent Temperature Transmitter, which is a new generation of Fieldbus Intelligent Temperature Transmitter, also an indispensable field device in control processing. It is integrated with a variety of functional modules, to realize not only the general testing functions, also the complicated control strategy.



Digital technology is applied in NCS-TT105, which has been used in a wide range of thermal resistance and thermocouple sensors. It has a wide measuring range. Because of the simple interface between the field and control room, the costs of installation, operation and maintenance are reduced a lot.



NCS-TT105 Series of Intelligent Temperature Transmitters, complied with FF Protocol, have been widely used in petroleum, chemical, metallurgy, electricity, cement,etc.
