Siemens SITRANS TR200 Temperature Transmitter

Overview

Siemens TR200 — the SITRANS TR200 — is a compact, DIN rail mounted temperature transmitter designed to convert RTD, thermocouple, resistance, and millivolt sensor signals into a standardized 4–20 mA output for control-panel installation. Built for reliable operation across the full ambient temperature range with potted electronics and NAMUR NE43-compliant sensor-failure alarming, the SITRANS TR200 gives panel builders and process engineers a compact, field-configurable signal-conditioning solution for Pt100 RTD inputs without the space and cost of a head-mounted transmitter. Its galvanic isolation and difference/average measurement functions make it a versatile choice for control cabinets throughout Oman’s process and utility industries.

As the official authorized partner and exclusive regional representative for Siemens, Seven Star LLC proudly supplies the Siemens TR200 temperature transmitter to industrial buyers across the Sultanate of Oman and the wider GCC. Every unit shipped from our regional stock is a genuine Siemens instrument, backed by full manufacturer warranty and in-country technical support, giving panel builders and system integrators in Muscat, Sohar, and Salalah confidence in authentic instrumentation rather than uncertain grey-market alternatives.

Measurement Principle

When wired to a Pt100 RTD, the SITRANS TR200 reads the platinum element’s resistance, which varies in a precise, repeatable relationship with temperature per IEC 60751, and linearizes that reading into a standard 4–20 mA current-loop signal that any downstream PLC or DCS analog input card can accept directly. Single or dual-point trim calibration, along with support for custom characteristic curves, allows the transmitter to be matched precisely to the connected RTD, reducing systematic error across the full measuring span. Because the RTD sensing element itself is solid-state with no moving parts, the overall signal chain introduces no mechanical wear and remains stable over long operating periods once correctly configured and trimmed.

The TR200 continuously supervises the health of the RTD input, and if a sensor open-circuit or short-circuit fault occurs, it drives the 4–20 mA output to a defined NAMUR NE43 alarm state so the connected control system can immediately distinguish a genuine process reading from a failed-sensor condition. This built-in diagnostic capability reduces the risk of a silent sensor failure going unnoticed on a critical monitoring loop, which is particularly valuable on unattended utility and process-monitoring panels operating continuously across regional industrial sites.

Engineering Design of the Siemens TR200

The SITRANS TR200 is housed in a compact, potted-electronics enclosure designed for standard 35 mm DIN rail mounting inside a control cabinet, with removable screw terminals for the RTD, thermocouple, or resistance input on one side and the 4–20 mA power/signal loop on the other. The potted construction protects the internal electronics from vibration, dust, and humidity inside control panels located in harsh industrial environments, while explosion-protected European variants extend its use into classified hazardous-area control rooms.

Configuration of range, sensor type, and alarm behavior is carried out via DIP switches and trim potentiometers on early variants, or through SIMATIC PDM software over HART communication on HART-enabled versions, giving specifiers the flexibility to reconfigure the transmitter in the field as process requirements change without swapping hardware. Galvanic isolation between the input and output circuits protects downstream control equipment from ground-loop and transient electrical interference, an important consideration in large industrial installations with long cable runs across multiple buildings or process areas.

Key Features

The Siemens TR200 temperature transmitter delivers compact, panel-mounted RTD signal conditioning built for reliable long-term control-cabinet service.

• The Siemens TR200 accepts RTD, thermocouple, resistance, and millivolt sensor inputs, giving panel builders a single transmitter platform for multiple sensor types.
• Converts Pt100 RTD signals into a standardized, linearized 4–20 mA output compatible with any standard analog PLC or DCS input.
• NAMUR NE43-compliant sensor-failure alarming drives the output to a defined fault state on an open or short-circuit RTD condition.
• Single or dual-point trim calibration and custom characteristic curves allow precise matching to the connected RTD sensor.
• Galvanic isolation between input and output circuits protects downstream control equipment from ground loops and electrical transients.
• The Siemens TR200 compact 35 mm DIN rail mounting saves control-cabinet space compared with head-mounted transmitter alternatives.
• Potted electronics construction resists vibration, dust, and humidity inside industrial control panels.
• Explosion-protected European variants extend suitability into classified hazardous-area control rooms.

Industrial Applications

The Siemens TR200 is widely specified in control-panel and switchgear-room installations across petrochemical, power generation, and general process industries throughout the region, wherever an RTD signal needs to be converted to a standard 4–20 mA loop before reaching a PLC or DCS analog input. District cooling plants and commercial HVAC control panels across Muscat rely on the TR200 to condition chilled-water RTD signals for building-management systems, while RO desalination plants and water treatment facilities use it to standardize temperature readings across multiple process skids feeding a central control room. The Siemens TR200 is also common in manufacturing and light-industrial facilities in Oman’s growing industrial zones also specify the TR200 for its compact DIN rail footprint, which simplifies retrofitting signal conditioning into existing, space-constrained control cabinets.

As the officially authorized partner for Siemens, Seven Star LLC distributes the Siemens TR200 temperature transmitter to panel builders, system integrators, and plant operators throughout Oman, the wider GCC, and specifically within the Sohar and Salalah economic zones, where petrochemical, metals, and logistics facilities depend on genuine, locally stocked Siemens instrumentation and responsive after-sales support. Hospitality developments and hospital complexes across Muscat also incorporate TR200-class transmitters into their building-management control panels, where reliable RTD signal conditioning directly supports energy efficiency and occupant comfort control. Sourcing through Seven Star LLC ensures customers in the region receive authentic Siemens hardware with full warranty coverage rather than uncertain third-party imports.
