TEC Elements, Resistive Heaters, Thermistors, and Thermocouples

Features

Thorlabs offers a wide range of thermal management accessories, including thermoelectric coolers, resistive heaters, thermistors, and temperature transducers. Thermoelectric coolers are ideal for total and precise temperature regulation. These devices can both cool and heat, allowing for quick response to thermal drift or shock. For applications that require only heating or steady-state regulation slightly above room temperature, resistive heaters are a reliable and easily regulated heat source. Regardless of application, temperature monitoring is essential for any temperature regulation system. Thorlabs' thermistors and thermocouples provide precise and accurate temperature measurements.

We offer three different thermoelectric coolers (TEC3-2.5, TEC3-6, and TEC1.4-6), all of which are ideal for medium to large heat-pumping applications. These work well with both our TED200C 12 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers, which are compatible with the PRO800 Chassis. When using a TEC for thermal regulation, care should be taken to electrically isolate both sides of the TEC.

Thorlabs offers three types of resistive heaters: foil, cartridge, and metal ceramic. The HT10K and TLK-H are resistive foil heaters with a pressure-sensitive adhesive backing and a 10 kΩ NTC thermistor integrated directly onto the heater. The HT15W is a miniature 15 W cartridge heater, which can be used for many applications requiring small areas to be heated. Our metal ceramic heaters come in either round (HT19R) or square (HT24S and HT24S2) geometries and provide fast thermal response. These small but high powered heaters are ideal for thermal regulation of optical components. All of the heaters sold here are compatible with Thorlabs' TC200 temperature controller.

We also offer three models of thermistors and temperature transducers. The TH10K is a 10 kΩ thermistor with 1 °C accuracy that is meant to be used in common TEC applications. The TH100PT is a 100 Ω platinum Resistance Temperature Detector (RTD) with a positive linear temperature response. These thermistors are compatible with the TC200 temperature controller. Finally, the AD590 is an integrated circuit (IC) temperature transducer with an output current that is proportional to absolute temperature. All our thermistors and AD590 temperature transducers are compatible with the TED200C 12 W Benchtop Laser Diode Temperature Controller and our rack-mountable temperature controllers. For high temperature applications, constantan or manganese wires may be used.

Response from Mike at Thorlabs: Thank you for your feedback. The temperature range for the HT10K and TLK-H is -32 to 100 °C (-26 to 212 °F). Based on your feedback this specification has been added to the web presentation for these parts.

I don't see a maximum temperature spec on HT10K or TLK-H. Can you provide this information?

What is the maximum operational temperature for the HT19R heater element? The heater element HT19R ships with a note saying the maximum is 180 C, while the data sheet online says 400 C.

Response from Sean at Thorlabs: Thank you for your pointing out this inconsistency. 400 °C is the correct maximum temperature specification. It appears that the item shipped with an older, incorrect version of the spec sheet; we are working with the production team to get the items in inventory corrected now.

How long are the leads on the HT10K? Or can you just solder on your own?

Response from Tim at Thorlabs: Thank you for your feedback. We will add the cable as a standalone item shortly (with HIROSE connectors for mating with TC200). For immediate assistance with a compatible cable, please contact us at techsupport@thorlabs.com.

Would be great if Thorlabs also sold connecting cable (connector one end and alligator or other quick clips on other end) to go between Thermistor, heating elements and one of the standard temperature controllers.

Performance values of the TEC are given above as a function of TH, the temperature of the hot surface of the TEC. Imax is the maximum allowed current across the TEC element and Vmax is the maximum allowed voltage difference. These values should not be exceeded. Qmax is the maximum heat load that the TEC can handle; Tmax is the maximum temperature difference between the hot and cold surfaces of the TEC in a dry nitrogen environment.

When choosing a TEC, it is important to know the heat load of the system (how much heat must be transferred away from the device) and to match that load with a capable TEC. The TEC should be rated for a maximum heat load above that which is emitted by the system. Proper thermal contact is necessary for optimal heat transfer. Ensuring that the TEC is of proper size for the system is important as well as using thermal tape or grease to help facilitate heat transfer. It is important to note that the heat transfer efficiency is affected by the ambient environment. Large changes in background temperature or significant humidity can hamper heat flow. These factors should be taken into account when choosing an appropriate TEC.

These 1" x 3" (25.4 mm x 76.2 mm) foil heating elements are useful for many lab applications. They have an integrated thermistor for closed-loop temperature control and an acrylic pressure-sensitive adhesive backing for easy installation. Both models use the same heating element and are compatible with our TC200 temperature controller. Additionally, the TLK-H includes a 6-pin hirose connector for direct connection to the TC200 with no soldering. Both heaters are flexible for use in applications such as heating lens tubes, as shown in the photo to the right. In this application, the lens tube can be isolated from the rest of the system using a Thermally Insulating Adapter.
