Temperature Measurement
Transmitters for rail mounting
SITRANS TR300 two-wire system, universal, HART
■ Overview
■ Application
SITRANS TR300 transmitters can be used in all industrial 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 thermometers (2, 3 or 4-wire system)
• Thermocouples
• Resistance-based sensors and DC voltage sources
The output signal is a direct current from 4 to 20 mA in accordance with the sensor characteristic, superimposed by the digital HART signal.
Transmitters of the "intrinsically safe" type of protection can be installed within potentially explosive atmospheres. The devices
comply with the Directive 2014/34/EU (ATEX).
■ Function
"HART" to beat - the universal SITRANS TR300 transmitter
• Two-wire devices for 4 to 20 mA, HART
• Device for rail mounting
• Universal input for virtually any type of temperature sensor
• Configurable over HART

The SITRANS TR300 is configured over HART. This can be done
using a handheld communicator or even more conveniently with
a HART modem and the SIMATIC PDM parameterization software. The configuration data are then permanently stored in the
non-volatile memory (EEPROM).
Once the sensors and power supply have been correctly connected, the transmitter outputs a temperature-linear output signal and the diagnostics LED displays a green light. In the case
of a sensor short-circuit, the LED flashes red, an internal device
fault is indicated by a steady red light.
The test socket can be used to connect an ammeter at any time
for monitoring purposes and plausibility checks. The output current can be read without any interruption, or even without opening the current loop.

The digital accuracy is the accuracy after the analog/digital conversion including linearization and calculation of the measured
value.
An additional error is generated in the output current 4 to 20 mA
as a result of the digital/analog conversion of 0,025 % of the set
span (digital-analog error).
The total error under reference conditions at the analog output is
the sum from the digital error and the digital-analog error (poss.
with the addition of cold junction errors in the case of thermocouple measurements).
