Set up was simple!I set this unit up on my test bench. It was simple and worked well. We will install it on our production machine within the next few weeks. I'll update this review after we see how it works on a running machine. I gave it 4 stars until we try it in production.
Infrared Sensor/Transmitter, Item# OS137A-1-K
Hi, Can I use this to measure glass surface at a distance of 20cm?
Do I need to tile the angle or perpendicular to the target surface, which is a piece of glass.
Asked by: John Ho
The OS137A-1-K can measure glass surface temperatures from 0 to 100C, The field of view is 10:1, so that at 20 cm away the spot size is 3.7 cm when the IR sensor is perpendicular to the surface that you are measuring. Please note that the spot size needs to be smaller than the object that you are measuring. Also note that this sensor will read the glass surface only not the objects behind the glass surface. Thank you.
