The MPTC-02 Multipoint Temperature Sensor, together with a guide tube and heat sink is designed for use in industrial processes in which it is necessary to monitor the temperature at a number of positions within a vessel, a reactor, a column or a process system. By measuring at a number of points with a single assembly, engineers obtain a better understanding of the temperature gradients and process conditions than is possible with a single-point sensor.
The MPTC-02 has a design that includes a guide tube and contact with a heat sink. The individual thermocouples are fitted into the guide tubes, and the heat sink blocks ensure that there is constant contact between the guide tubes and the outer protective tube. This kind of construction also means that the thermocouple elements are easier to handle and maintain in the field.
The sensor is available with Type K, J, T or N thermocouples ; both grounded and ungrounded thermocouple junctions can be provided. A wide variety of sheath materials—such as 304, 316 and 321 stainless steel, Inconel 600, Incoloy 800, Monel and Pyrosil D—enables the assembly to be set up to meet various process requirements.
The MPTC-02 is especially well suited to use in distillation and separation processes, for carrying out temperature profiling in heat exchangers, for polymerisation, for chemical processing, in reactors, in distillation columns, for crude-oil desalting, and for use in fluidised catalytic cracking and visbreaking units.
For demanding installations, the available enclosure types are aluminium, stainless steel and cast iron, and NEMA 4X and IP68 ratings are provided for continuous outdoor use. Explosion-proof enclosure types are also available for use in hazardous locations.
For any applications in which documented verification is required, temperature calibration traceable to NIST up to 1200°C can be provided. Additionally, radiographic examination, pressure testing and NDT testing can be requested.
The MPTC-02 offers a configurable approach to multipoint temperature profiling, process optimization, and the monitoring of critical temperatures in complex industrial processes.

Temperature Transmitter | Tempotech Controls Inc
A temperature transmitter takes the temperature data from a sensor, like an RTD or thermocouple, and converts it into a standard signal, usually 4-20mA or 0-10V. This signal can be sent to control systems, PLCs, or monitoring equipment to keep track of temperature in real-time.

Video Transcription: Temperature Transmitter Technology & Application
[00:05] A temperature transmitter is a critical component in industrial automation that converts low-level sensor signals into standardized outputs. This ensures accurate, reliable, and long-distance signal transmission for complex control systems.
[00:14] Thermocouple and RTD sensors are the industry standards for measuring the temperature of processed media. However, in challenging environments—characterized by high temperatures, electromagnetic interference (EMI), or long cable runs—the raw signals from these sensors can degrade.
[00:33] This signal degradation, often caused by wire resistance and electrical noise, can lead to inaccurate readings. To mitigate these issues, temperature transmitters are used to amplify, condition, and convert sensor data into a standardized 4-20mA output, ensuring high-integrity data across the plant.
[00:59] Several signal types are used depending on the application:
4 to 20 mA Analog Signal: The most common standard, highly resistant to noise and ideal for long distances.
0 to 10V: A common analog option, though more susceptible to signal loss over length.
Digital Signals (HART & Modbus): Used for advanced remote communication and diagnostics.
RS485/RS232: Essential for integrating transmitters with PLCs and SCADA systems.
[01:35] The Tempotech TT367 series temperature transmitters are engineered for versatility. They offer precise sensor-transmitter matching and robust protection against interference. Configurable via the HART protocol, these units allow for easy setup and reliable field operation.
[01:56] Key reliability features include open/short-circuit detection, incorrect wiring alerts, and NAMUR NE43 failure standards. The TT367 supports RTD, TC, Ohm, and Millivolt inputs, making it a universal solution for your instrumentation needs.
[02:26] With integrated dot-matrix displays and easy configuration options, our transmitters provide the precision you can trust. Contact our technical sales team today to find the best transmitter for your application.
