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.

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 tells you the length of the wire in inches for that specific part number. I will send a ticket in to have this issue resolved.

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.

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.

What is the accuracy of these SA3-J-120-SRTC?

Asked by: Linnie
Thank you for engaging with OMEGA. The accuracy of the SA3-J is greater of +/- 2.2°C or 0.75%

is it possible to have a connector that measures temperatures from -40 to 180 or whatever high tempoerature with these thermocouples or there is just a connector from -26 to 180 as mentionned.

Asked by: moun1992
Thank you for your inquiry! Often, the T/C connectors aren't rated for the same temperatures as the thermocouples they are connected to, this is fine. However, the T/C connector type should always match the T/C type.
