The SA1-RTD surface-mount RTD temperature sensor mounts on flat or curved surfaces and provides Class A accuracy for critical temperature monitoring applications. Based on a 2 x 2 x 0.8 mm thin-film platinum RTD and supplied with bare 3-wire leads as a standard configuration (connector optional), itcan be customized for use in a wide variety of applications. The sensor can be easily applied with its selfadhesive

backing, or positioned permanently with OMEGABOND™ cements.
Use the SA1-RTD to monitor chip, heat sink, and environmental temperatures in electronic devices; check piping or ducting temperatures;monitor motor and transformer core heat; test insulation capabilities; and check other applications in which surface and/or gradient temperatures need to be monitored or controlled.

Rated 5 out of 5 by from Communication There were some issues with raw materials and was never communicated. I had to expedite the order to find out that the order has been delayed. However, Omega was very helpful to escalate the issue and sort out the raw material issue in good time.

I'm interested in purchasing one of these, but I can't find information regarding acceptable current bounds; can you give me an estimate on minimum required current to operate this sensor, and maximum not to toast it?

Asked by: EAML
Hi EAML Thank you for the inquiry. 1 mA or less is the specified current level. A higher current can lead to self heating error and should be avoided. Lower current levels can be used and the level is determined by the instrumentation used. We do not have a specification on mA levels which can damage the sensor. Best regards OMEGA

It says, 'back can be reapplied' in the product description. Is there back adhesive material that can be used for this RTD?

Asked by: RTD_engineer
The SA1-RTD if carefully removed can be reattached but each time will lose some of its adherent properties. Sometimes when it no longer sticks a piece of Kapton tape can be laid over the top to hold it in place,

What is the best method to cut the PFA wire covering to get access to more of the leads?

Asked by: Brad Nickname in Use
Omega sells the TW-6 which is designed to remove the outer insulation of wires with ease. You can enter TW-6 in the search box on Omega's web page for further details.

Would the self-adhesive work on a concrete surface?

Asked by: gd65
Thank you for your inquiry. No, the adhesive will not work on a concrete surface.

What are the dimensions (width and thickess) of the cable?

Asked by: Dave Z
Thank you for your inquiry Dave Z. The wire gauge of this sensor is 26 AWG. It has a nominal size of 0.060" x 0.064".

In the spec sheet, there are tolerances listed for down to -200°C. My application requires use down to -100°C; is -73°C the cutoff for optimal precision, or does the sensor stop working below this minimum temperature rating?

Asked by: emj2
These RTD probes will work down to -100C and lower but the adhesive is not effective below-73C so the should be mechanically secured.

What is the recommended method of calibrating these sensors?

Asked by: Pharma_L
Thank for your inquiry. Surface Wire Sensor when calibrated, is done before the adhesive pad is attached. Not after. We recommend purchase calibrated sensors from OMEGA.
