NCS-TT306H series HART temperature transmitter

NCS-TT306H series HART temperature transmitter is a high-precision, low-temperature drift, and high-reliability product, including head-mounted NCS-TT306H and rail-mounted NCS-TT306H-R. It is indispensable in process control. Field equipment. The device integrates a wealth of functional modules, which can not only implement general detection functions, but also implement complex control strategies.

NCS-TT306H adopts digital technology and can be applied to a variety of thermal resistance and thermocouple sensors. It has a wide range and a simple interface between the field and the control room, and can greatly reduce installation, operation and maintenance costs.

NCS-TT306H series temperature transmitter supports 4-20mA+HART protocol and LCD display, and can be widely used in petroleum, chemical, electric power, metallurgy and other industries.

NCS-TT306 Series HART Temperature Transmitter wiring shown:

The power supply and bus signal of the temperature transmitter share a pair of cables, which are called bus cables. It is recommended to use the dedicated fieldbus cable recommended by IEC61158-2. Signal cables and bus cables should not share conduits or open wire troughs with power cords of other equipment, and should be kept away from high-power equipment. The shielded wires at both ends of the bus are grounded using single-ended grounding.
