7NG0350-0BA01-0AF0-ZE00 SIEMENS Exclusive SITRANS TF320 Temperature Transmitter Original Brand New

The SIEMENS 7NG0350-0BA01-0AF0-ZE00 SITRANS TF320 is a modern, dual-chamber temperature transmitter engineered for highly reliable industrial process measurement. With a rugged die-cast aluminum enclosure and versatile mounting options for wall or pipe installations, this device delivers robust performance even in demanding environments. It supports one configurable input with galvanic isolation and offers a standard 2-wire output, making it an ideal choice for precise and stable temperature monitoring in various process industries.

The SITRANS TF320 is available with or without HART communication, ensuring flexibility for different user requirements. The HART-enabled version provides full digital communication alongside the traditional 4–20 mA output, enabling advanced diagnostics, configuration, and process optimization. For non-HART versions, configuration is carried out using PC software tools such as SIPROM T, offering convenient and reliable parameterization. With automatic error detection for sensor failures or short circuits, the device ensures maximum operational security and reliability.

Overview

This transmitter features a universal input that supports RTDs, thermocouples, resistance signals, and millivolt inputs. The integrated cold junction ensures accurate thermocouple measurement, while signal amplification and linearization provide stable and precise output performance. Its two-wire design minimizes installation complexity, and the optional local operation allows users to configure key parameters directly on the device.

Function

The SITRANS TF320 automatically detects sensor interruptions, short circuits, and abnormal operating conditions, enhancing overall system reliability. Practical test terminals allow engineers to measure 4–20 mA signals directly with an ammeter without disturbing the output loop, simplifying maintenance and troubleshooting. Combined with PROFINET and SIMATIC PDM compatibility, this transmitter ensures seamless integration into modern automation systems.

Principle of Operation

The transmitter receives input signals from sensors such as RTDs or thermocouples, amplifies and linearizes them, and transmits the measured values as a direct current output. The galvanic isolation between input and output protects against interference, ensuring safe and accurate measurement. In the HART version, digital communication supports live diagnostics, remote configuration, and enhanced process control, allowing operators to achieve greater efficiency and reliability.
