7NG0340-0BA01-0CF0-ZE27 SIEMENS Exclusive SITRANS TF320 Temperature Transmitter Original Brand New

The SIEMENS 7NG0340-0BA01-0CF0-ZE27 SITRANS TF320 is a robust and highly reliable temperature transmitter designed for precision measurement in demanding industrial environments. It comes with a single chamber enclosure, making it suitable for both wall and pipe mounting applications. The transmitter offers one configurable input and a galvanically isolated 2-wire output, ensuring stable and interference-free signal transmission. With HART communication support (4–20 mA), it allows flexible integration into existing automation systems while ensuring easy parameterization and diagnostics.

Engineered for reliability, the SITRANS TF320 features a die-cast aluminum enclosure that is flameproof and explosion-proof, making it suitable for hazardous locations. Equipped with M20 x 1.5 connections, the device provides secure installation and protection against harsh environments. This transmitter is designed to support a wide range of input signals including RTD Pt100 according to IEC 60751, thermocouples, resistance, and millivolt signals, offering unmatched versatility in temperature measurement applications.

Overview

The SITRANS TF320 is a 2-wire temperature transmitter with optional HART communication interface. It offers a universal input for almost all types of temperature sensors and can be configured via PC, HART 7 communicator, or optional local operation. This flexibility makes it suitable for diverse applications across industries where precise and reliable temperature monitoring is required.

Function and Configuration

With HART protocol version 7, users can configure the device using a PC or handheld communicator. For versions without HART, configuration is possible through PC using SIPROM T software and a special modem. Optional local operation enables fast access to essential parameters directly on the device, reducing setup time.

Principle of Operation

The SITRANS TF320 amplifies and linearizes input signals from RTDs, thermocouples, resistances, or mV sources. Both input and output are galvanically isolated, ensuring signal integrity. The integrated cold junction provides accurate thermocouple measurements. The device delivers a linear 4–20 mA output, with HART models offering digital communication for diagnostics, online monitoring, and remote configuration. Built-in sensor monitoring allows detection of interruptions or short circuits, and test terminals enable direct measurement of output current without disrupting operations.
