The TC11 Direct Immersion Thermocouple Probe is designed for compact industrial and OEM installations requiring fast, dependable temperature measurement without a connection head or complete thermowell assembly.Not every temperature measurement application requires a complete thermowell assembly or connection head. For many industrial and OEM installations, a compact, fast-responding thermocouple probe is the better choice. The TC11 Miniature Thermocouple Probe with Lead Wire is designed for direct immersion temperature measurement where space is limited and dependable performance is essential.

Manufactured using mineral insulated (MGO) cable, the TC11 combines excellent heat transfer with rugged mechanical strength, making it suitable for continuous operation in demanding industrial environments. The compact probe construction allows it to respond quickly to temperature changes while withstanding vibration, moisture, and harsh process conditions.

To suit a wide range of applications, the TC11 is available in Type J, K, T, E, and N thermocouples, with grounded, ungrounded, or exposed junctions depending on the required response time, electrical isolation, and process conditions. Multiple sheath diameters, immersion lengths, lead wire options, connector styles, and process fittings allow each sensor to be configured for the specific installation rather than forcing customers to adapt their equipment to a standard product.

A wide selection of sheath materials, including 304SS, 316SS, 321SS, Inconel® 600, Incoloy® 800, Monel, and other specialty alloys, makes the TC11 suitable for applications involving elevated temperatures, corrosive environments, and demanding industrial processes. The sensor can also be supplied with various insulation materials and armored lead wire options to match the operating environment and installation requirements.

The TC11 is commonly used in industrial furnaces, ovens, heat treatment equipment, plastics processing machinery, packaging equipment, food processing systems, laboratories, OEM machinery, pilot plants, and general process temperature measurement. Whether monitoring air, liquids, gases, or solid surfaces, the TC11 provides dependable temperature measurement for both new equipment and replacement applications.

Every application has different temperature ranges, process media, and installation requirements. If you’re unsure which thermocouple type, sheath material, junction style, or process fitting is best for your application, Tempotech Controls’ technical team can help you select the most suitable configuration before ordering. Calibration services are also available for applications requiring documented measurement accuracy.

Temperature Transmitter | Tempotech Controls Inc

PT2M44S

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.

Read transcript

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.
