These thermocouples can be used in outdoor and wet environments, including bright sunlight, with little to no effect on performance or accuracy. Our unique construction techniques provides a fast responding thermocouple junction in a thin and flexible mounting pad. These SA3 thermocouples are available in 2 styles, stripped #30AWG solid leads, or with a miniature color coded connector.

Specifications
Thermocouple: ANSI color code J/K/T/E or IEC color code JI/KI/TI/EI
Accuracy: Special limits of error
Junction Type: Ungrounded sensor construction
    • Polyimide tape base with silicone adhesive and paper peel sheet
    • Polyimide tape cover
    • PFA insulated and jacketed 30 AWG cable
    • Glass filled nylon connector when specified
Temperature Range:
    Sensor: -17 to 260°C (0 to 500°F)
    Connector: -29 to 180°C (-20 to 356°F)
Insulation Resistance: 100 M? minimum at 100 Vdc at room temperature and sensor mounted to surface
Rated 1 out of 5 by from fragile, thin wire and insulation, not robust Fragile, thin wire and insulation, not robust. One wire broke after first use.

Rated 1 out of 5 by from adhesive did not stick to stainless steel poor adhesive. Did not stick to cleaned stainless steel surfaces. Had to apply anothe layer of fiberglass high heat tape to get them to stay in place.

Rated 5 out of 5 by from Self-adhesive thermocouples This tc serves its purpose well! Easy to install but you have to be very careful not to damage it.

Rated 1 out of 5 by from False advertisement - very disappointed Even now you picture shows a thermocouple with a yellow connector at the end. I ordered the parts thinking that it was connectorized, but received the TCs with bare wire. Very disappointed in Omega.

Rated 3 out of 5 by from Fragile If you want to remove and re-apply these thermocouples don't be surprised if junctions break giving false data. For the first application they work well.

Rated 5 out of 5 by from Great product Worked great for the application. Well made and consistent.

Rated 5 out of 5 by from Love This Product! Works like a Charm! Need to attach these to a wax surface to go through an investment casting process and study how long the molds take to dry. These self adhesives work fantastic to stick to the mold and I would recommend.

Rated 4 out of 5 by from Lab Test Works good in lab test and connects to equipment well.

In the product details, there is a column called "Minimum Temperature Measurement". The result is in inches.....specifically 36in for the device I ordered. What does that mean?

Asked by: Korpz
Thank You for your question. That is a website error. The length in inches describes the length of the wire being used in for that part in accordance to that part number. I will submit a ticket in order to have that category title fixed.

What is the accuracy of the SA3-K-SRTC? What is the response time of the SA3-K-SRTC?

Asked by: Insert here
Thank you for your inquiry. The accuracy of the SA3-K-SRTC is +/- 1.1°C or 0.4% of the reading, whichever is greater. For response time, please email temp@dwyeromega.com

are these well insulated electrically, what if these are pasted on high voltage copper bus bars with voltage up to 500V to 1000V are there any other products that for surface mount application that can be used on copper bsubar with 1000V on it.

Asked by: Amit
Hi Amit, The adhesive pad is electrically insulative but we do not provide a voltage rating. If applied to a surface with potential the leads should be considered to be at the same potential. Best regards OMEGA

1. what is the accuracy of SA3-J-SRTC? 2. what is the response time of SA3-J-SRTC? 2 seconds or 0.3 seconds? Thank you

Asked by: Validation guy
Surface Thermocouple achieves response times of less than 0.15 seconds.

I want to measure the metal tube surface temperature inside a tube in shell heat exchanger (undergraduate lab). The environment would be steam/water up to about 120 degrees C. Will the SA3 thermocouples function in this environment? Other suggestions?

Asked by: Rolf
Thank you for your inquiry Rolf. This probe works on wet environments that don't include the full water immersion and powerful water jets.

Can you get this item already attached to a connector for high temperatures?

Asked by: cyto
This would need to be handled by contacting the Temperature Engineering group directly at temp@omega.com.

Are these thermocouples applicable in Vacuum environment (5torr- 10torr) pressure? at around 200 deg.

Asked by: Anirudh
Thank you for your inquiry. These sensors are NOT vacuum rated.
