The actual definition of target size (area measured) will vary depending upon the supplier, and it is price dependent. Other optical configurations vary from small spot (0.030 in dia.) for close-up pinpoint WebDec 2, 2024 · Temperature Sensors have some advantages in comparison with other practical instruments. Temperature sensors are low-cost, precise, and extremely reliable in repeated experiments. They are desirable for both embedded and surface mount applications. They have a faster response time because of the lower thermal mass.
