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.

Good RTDs
RTDs are performing well, as expected. No issues regarding quality or anything else.

Excellent Turn-Around Time
Amazed at the extremely short-lead time. It arrived prior to the expected arrival time, and kept the project it was needed for Operationally Ready prior to the Completion Timeline.

As Advertised
I have used these on several projects, and the work exactly as advertised. I have not had a problem with any of them.

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?
Hi EAML,
Normal excitation current is 1mA or less. Minimum current level is determined by the instrument being used.
Higher levels will cause readings to be affected by self heating errors. We do not have established current level which can cause burnout.
Best regards
OMEGA

What are the color codes of the 3 wires?
Does anyone know what the colors correspond to? Thanks.

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

Hi, could you please send me or link here a "Resistance vs Temperature table" for the SA1-RTD (3 wires)? Regards.
Thank you for your inquiry Sborzy. Please review the following link for the table: https://assets.omega.com/tech-ref-legacy-pdfs/z252-254.pdf

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

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

Does anybody have a recommendation for temperature sensing device to connect to this sensor? One that could connect to a computer, ideally.
You may want to consider the SA1-RTD-80 with the HH804U handheld meter along with the software HH800-SW (windows software and USB cable) which allows for real time data logging to a PC.
For extensive data logging a DC power jack is available
HH804U Meter $173.88 each in stock
Comes complete with HH804-CONNECTOR (one per channel), protective rubber boot,
NIST certificate (no points), 4 “AAA” batteries, and operator’s manual.

HH800-SW $23.18 in stock
Windows software and USB cable (USB models only)

If a thermocouple can be considered in place of a RTD , for example the SA1-K-72- SRTC is a good option. We offer the Thermocouple Data logger with USB interface the OM-EL-USB-TC which accepts a J, K or T type thermocouple. This plugs directly into a USB Port – No USB cable is required
https://www.omega.com/en-us/control-and-monitoring-devices/data-loggers/p/OM-EL-USB-TC-Series
and the specifications sheet is: https://br.omega.com/omegaFiles/das/pdf/OM-EL-USB-TC.pdf
Thank you for your question.

The data sheet mentions installation using Omegabond thermal epoxy. What is the correct/recommended process for epoxy install? Does the polyimide tape get completely removed, and then epoxy the RTD on? Seems like tape on epoxy would not create a good bond
Thank you for your inquiry RPeebs. You will need to use thermal conductive epoxy that way you don't block the heat from coming into contact with the probe. The pad should not affect the temperature measurement if you decide to use epoxy in conjunction with the adhesive pad.
