Product Specs

The SA1-RTD is a surface temperature sensor that can be applied to most clean, dry surfaces.  Just peel off the release sheet on the bottom of the sensor and the silicone adhesive bonds the sensor to the surface, no cements or epoxies to mix, apply and cure. 

The thin design of the SA1-RTD minimizes the effects of having the sensor attached to the surface of interest.  Containing a thin film platinum sensing element, the SA1-RTD resistance is not affected by mounting to curved surfaces.  With a fast thermal response time, the SA1-RTD will quickly respond to changes in temperature for fast, reliable measurements. 



Rated 3 out of 5 by from RTD sensors kit Used with RDXL65D - 6 channel Temperature Data Logger with Touch Screen. RTD sensors are OK, but using with stereo(3-pole) 3.5 mm connectors (RDXL65D) is a bad idea. Stereo connectors DO Not provide reliable low resistance contact, which shows as inconsistent measurement results.

Hi I purchased a pack, I received it alread, Packing Slip: 834570 Order: HC00491380, Orthosensor INC Can you please provide product DATA SHEET, and if available IFU intructions for use? mainly I need to know what each of the black,black,red wires are?

Asked by: Andres Arango
The only DATA SHEET that Omega can offer for the SA1-RTD-B series can be found by clicking Data Sheet (PDF) underneath the bullet points on the link included. We have no formal wiring diagrams but the way that RTD is wired is that both Black wires are attached to one side of the sensing element and the Red is attached to the other leg of the sensing element. Some standard terminology would be Red to SENSE (+) one of the Black to SENSE (-) and the last Black to Ground. https://www.omega.com/en-us/sensors-and-sensing-equipment/temperature/sensors/surface-sensors/p/SA1-RTD-series
