SITRANS TR320 (HART, Universal) là một bộ chuyển đổi nhiệt độ của Siemens, được thiết kế để chuyển đổi tín hiệu nhiệt độ từ các cảm biến nhiệt độ thành tín hiệu dòng điện 4 đến 20 mA và hỗ trợ giao thức HART, cho phép truyền thông hai chiều giữa cảm biến và hệ thống điều khiển, giám sát.

Dưới đây là một số điểm nổi bật về SITRANS TR320 (HART, Universal) của Siemens:

4 to 20 mA Output: SITRANS TR320 chuyển đổi tín hiệu nhiệt độ thành tín hiệu dòng điện 4 đến 20 mA, là một tín hiệu phổ biến trong hệ thống điều khiển và giám sát quy trình công nghiệp.
HART Communication: Bộ chuyển đổi SITRANS TR320 hỗ trợ giao thức HART, cho phép gửi và nhận dữ liệu nhiệt độ thông qua một giao thức truyền thông thông minh. Giao thức HART cung cấp truyền thông hai chiều giữa cảm biến và hệ thống điều khiển, giúp giám sát trạng thái của cảm biến và thực hiện cấu hình từ xa.
Universal Input: SITRANS TR320 được thiết kế với đầu vào "Universal", có thể hoạt động với nhiều loại cảm biến nhiệt độ khác nhau, bao gồm cả RTD và thermocouple, giúp đơn giản hóa quá trình cài đặt và tích hợp vào hệ thống điều khiển và giám sát.

SIL2/3 (with order note C20)

Application

SITRANS TR320 transmitters can be used in all sectors. Their compact design enables simple mounting on standard DIN rails on-site in protective boxes or in control cabinets. The following sensors/signal sources can be connected over their universal input module:

Resistance thermometer (2-wire, 3-wire, 4-wire connection)
Thermocouples
Linear resistance, potentiometer and DC voltage sources

With HART communication interface:

The output signal is a load-independent direct current from 4 to 20 mA in accordance with the input characteristic, superimposed by the digital HART signal.

Transmitters of the "intrinsically safe or Zone 2 increased safety" type of protection can be installed in hazardous areas. The device meets the requirements of the EU Directive 2014/34/EU (ATEX), the FM and CSA regulations as well as other national approvals.

Function

Without HART communications interface

For the SITRANS TR320 without HART functionality, parameters are assigned with the PC. Available for this purpose are a special modem and the software tool SIPROM T.

With HART communications interface:

The SITRANS TR320 is configured via HART. The configuration can be carried out using a handheld communicator or, more conveniently, with a HART modem and the SIMATIC PDM configuration software. The configuration data are then permanently stored in the non-volatile memory (EEPROM).

After correct connection of input and supply voltage, the transmitter outputs a temperature-linear output signal and the diagnostics LED is green. In case of external errors, e.g. sensor short circuit or interruption, the LED flashes red; an internal error is indicated by a permanent red light.

An ammeter can be connected at any time for checking and plausibility via the test terminals. The output current can be read without any interruption, or even without opening the current loop.
