7NG0357-0BA01-0CF0-ZE27 SIEMENS Exclusive SITRANS TF320 Temperature Transmitter Original Brand New

The SIEMENS 7NG0357-0BA01-0CF0-ZE27 SITRANS TF320 is a rugged and reliable temperature transmitter designed for demanding industrial applications. Housed in a die-cast aluminum dual-chamber enclosure, this transmitter ensures durability in environments where safety and reliability are paramount. The device supports wall or pipe mounting, providing flexibility during installation, and comes with one configurable input along with a galvanically isolated 2-wire output. Its explosion-proof enclosure (Ex d/XP) ensures compliance with stringent international standards for hazardous areas, making it a trusted choice for industries where safety cannot be compromised.

Designed as a 2-wire transmitter with a 4–20 mA analog output, the SITRANS TF320 accepts a wide range of sensor inputs including RTDs such as Pt100 (IEC 60751), thermocouples, Ω, and mV signals. Input signals are amplified and linearized, while galvanic isolation between input and output guarantees secure and reliable signal integrity. For thermocouple measurements, the device incorporates an internal cold junction compensation to maintain accuracy.

Overview

The SITRANS TF320 is available with and without HART communication interface. It offers universal sensor input, configuration through PC software, HART communicator, or optional local operation. Thanks to its advanced diagnostics and flexible setup, the transmitter adapts seamlessly to modern industrial requirements.

Function and Configuration

The HART-enabled version allows parameterization via SIMATIC PDM or a hand-held communicator, providing convenient access to diagnostics and online configuration. The non-HART model can be programmed with SIPROM T software and a dedicated modem. Optional local operation enables quick access to essential parameters directly on the device. In case of sensor failure, interruption, or short circuit, the SITRANS TF320 automatically detects errors, while test terminals allow direct measurement of 4–20 mA signals without disturbing the current loop.

Principle of Operation

By processing resistance thermometer or thermocouple signals, the SITRANS TF320 produces a stable, temperature-linear output signal ranging from 4 to 20 mA. This ensures dependable temperature monitoring and reliable integration into existing automation systems. The transmitter’s combination of robust design, versatile communication, and diagnostic features makes it a cornerstone for safe and efficient industrial temperature measurement.
