Product Specs

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.

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.

For a DAQ device with EX0, RTD+, RTD-, and COM ports (such as NI 9217), which wire go to which port? (For both 3-wire and 4-wire RTDs)

Asked by: tackoo
Thank you for your inquiry. COM & RTD- should have 1 Black Wire Each. EX0 & RTD+ should have 1 Red Wire Each.

Is the self adhesive backing easy to remove after a month or so of use? We need to monitor temperatures on piping for a month or so, then the sensors will need to be removed. Working temperature while monitoring will be around 90 degrees c

Asked by: Mikecandu
Thank you for your inquiry. The entire assembly can be removed carefully, but the self-adhesive properties will be lost.

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. https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/thermometers/p/HH804-805 HH800-SW $23.18 in stock Windows software and USB cable (USB models only) https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/thermometers/p/HH800-SW HH800-ADAPTOR $20.09 each in stock https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/hygrothermometers/p/HH800-ADAPTOR 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.
