7NG0340-0BA01-0BF0-ZE27 SIEMENS Exclusive SITRANS TF320 Temperature Transmitter Original Brand New

The SIEMENS 7NG0340-0BA01-0BF0-ZE27 SITRANS TF320 is a precision-engineered temperature transmitter designed for industrial applications requiring reliability, flexibility, and safety. With a single chamber enclosure suitable for wall or pipe mounting, this device is built with a robust die-cast aluminum housing that provides durability in demanding environments. It features a configurable universal input and a galvanically isolated two-wire output, making it ideal for integration in both standard and hazardous areas with intrinsic safety and non-incendive field wiring approvals.

This transmitter supports resistance thermometers (RTD), thermocouples (TC), and millivolt signals, offering wide compatibility across process industries. The inclusion of an internal cold junction ensures accurate thermocouple measurement, while the HART communication protocol enables seamless configuration, diagnostics, and data transmission. The TF320 version without HART functionality can also be configured using SIPROM T software, ensuring versatile usability across different installations.

Overview

The SITRANS TF320 operates as a two-wire transmitter, with and without HART capability. Its universal input accommodates nearly any type of temperature sensor, delivering linear and reliable output in the range of 4 to 20 mA. With simple configuration through PC tools or handheld communicators, as well as optional local operation, users can achieve rapid setup and parameterization without complexity.

Function

Built to meet the needs of modern process industries, the device combines accuracy with intelligent monitoring. The transmitter detects sensor interruptions and short circuits automatically, safeguarding the measurement chain. Practical test terminals allow direct current loop checks without system interruption, minimizing downtime during maintenance. Its design ensures galvanic isolation between input and output, increasing safety and reducing interference.

Principle of Operation

By amplifying and linearizing input signals from thermocouples, RTDs, or resistance measurements, the SITRANS TF320 ensures stable and accurate results. The HART-enabled version supports digital communication for diagnostics and real-time data monitoring, complementing the analog signal transmission. This flexibility makes the transmitter a dependable choice for applications in chemical plants, energy production, or any industry where precise temperature control is essential.
