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?

Thank you for your inquiry. The color code is 1 Red Wire & 2 Black Wires.

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.

Description

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.
