It can measure the temperature within a wide range of -200°C to 420°C. The device operates on a two-wire system, making it cost-effective and easy to install. Equipped with a display, the transmitter allows for convenient and real-time monitoring of temperature readings directly on-site. With high accuracy, low power consumption, and reliable performance, this temperature transmitter is an excellent choice for demanding industrial applications.

Feature

The RTD temperature transmitter integrates the transmitter and the RTD sensor into one unit, allowing for the direct measurement of temperature in liquids, steam, and gaseous media within the range of -200°C to 420°C in various industrial processes.
It can convert the temperature into a 4-20mA standardized output signal that is proportional to the electrical signal of the RTD.
The SUCH transmitter components are miniaturized, allowing them to be installed within the wiring box of the RTD, thus forming an integrated temperature transmitter.
It offers high accuracy, low power consumption, a wide operating temperature range, and is stable and reliable in operation.
Featuring a silicone rubber sealing structure, the transmitter is resistant to vibration and moisture, making it suitable for harsh field environments.

Transmitter Technology Parameters
Input	Thermal resistance Pt100
Output	The output of a 4-20mA DC signal within the measurement range can be linear with the output resistance signal of a resistance temperature detector (RTD), and also linear with the input temperature signal of the RTD; it can also be linear with the millivolt signal from a thermocouple input, or linear with the input temperature signal of a thermocouple thermometer.
The Basic Error	± 0.2%, ± 0.5%
Transmission Mode	Two-wire system
Operating Power Supply	Ranging from a minimum of 12V to a maximum of 35V.
Rated Operating Voltage	24V
Load	The load resistance calculated limit: *RL(max) = 50(Vmin - 12) (For a 24V system, the load resistance can be selected within the range of 0 to 600Ω, with a rated load of 250Ω.) Note:** When adjusting the range, both the zero point and full scale need to be repeatedly calibrated. For thermocouple transmitters, a 30-minute preheating is required before calibration.

FAQ

Q1: How does the RTD temperature transmitter communicate with control systems? ❯

The RTD temperature transmitter communicates with control systems via a 4-20mA output signal, which is a standard in industrial applications for transmitting temperature data over long distances with minimal signal degradation. The 4-20mA signal is proportional to the temperature measured by the RTD sensor, making it easy for control systems to interpret and adjust process variables accordingly. Additionally, the transmitter supports HART (Highway Addressable Remote Transducer) communication, which allows for more advanced features such as remote configuration, diagnostics, and data collection. This dual output capability ensures the transmitter can integrate seamlessly into a wide range of control and monitoring systems, providing both basic and advanced functionality depending on the application needs.

Q2: What is the advantage of the built-in display? ❯

The built-in display of the RTD temperature transmitter offers a significant advantage by providing real-time, on-site temperature readings directly on the device. This eliminates the need for operators to constantly refer to remote control systems or external displays, making it easier to monitor temperature fluctuations and respond quickly to any issues. The display allows for immediate visual feedback, improving operational efficiency and helping to avoid potential system failures. Furthermore, the display can often show important diagnostic information or error codes, which helps in troubleshooting and maintaining the system. It is particularly useful in environments where real-time visibility and quick decision-making are essential.

Q3: How is the transmitter powered? ❯

The RTD temperature transmitter operates using a two-wire system, meaning it is powered by the same two wires that carry the output signal to the control system. This design simplifies installation and reduces wiring costs, as no additional power supply is needed. The power is typically supplied via a DC power source, and the transmitter draws the required energy from the 4-20mA signal loop. This makes the device energy-efficient and ideal for applications where minimizing power consumption is a priority. The two-wire system also enhances reliability by reducing the complexity of the installation and ensuring fewer points of failure in the power distribution network.
