Descripción general del producto
The NCS-TT305 series Transmisor de temperatura HART is a high-precision, low-drift, high-reliability field device for process control. It integrates a broad set of functional modules, supporting both general temperature detection and more complex control strategies.
The transmitter uses digital signal processing, is compatible with a wide range of RTD and thermocouple sensors, and covers a wide measuring range. Its simple field-to-control-room interface helps reduce installation, commissioning, and maintenance costs.
The NCS-TT305 series supports 4-20mA + HART output with local LCD display, and is used across the petroleum, chemical, power, and metallurgy industries.
