There are many different kinds of sensors used in industry that would be called industrial sensors. Here is a good site for them www.i-s-i.com/

Industrial Sensors & Instruments, Inc. have been building sensors since 1983. Their website shows their large selection of the different sensors they manufacture. The descriptions they give of their products are both informative and educational.
I found several sites that said, "uv sensors, but only 2 that said, "industrial". The two sites are elecdir.com and ien.com.
The best is Sensors & Meters International. It has been voted by business.com.
You need to be more specific about the type of sensors you need information on. ie Automotive, Industrial, Automation?
Devco industrial heaters are mainly used, as the name already says, for industrial processing. They offer heaters such as band heaters, steam generators, cartridge heaters and temperature sensors.
PCO2 sensors are devices used to measure the partial pressure of carbon dioxide in a gas mixture, such as in medical equipment to monitor a patient's respiratory status. These sensors are designed to provide real-time data on CO2 levels for applications like environmental monitoring, industrial processes, and medical diagnostics.
Besides checking engineering texts for these diagrams, there are a number of places to look line. Planet Analog, Red Circuits, AMS, Industrial Controls, and Circuit Finder all have detailed diagrams of capacitive sensors.

Watlow produces industrial parts relating to temperature control and management. Their products include heaters, thermostats, controllers, and sensors.
Humidity sensors will work in any climate. However, humidity sensors are generally not used outdoors. Rather they're used in industrial applications where problems can occur if an environment becomes too dry or too humid. Humidity sensors actually work well in all climates. They are calibrated to be sensitive throughout the entire range of humidity, from 0-100%. It is best, however, to avoid placing sensors in areas where there is no wind so they have a change to stabilize.
The light source is typically a diode that emits either visible or infrared light. Other photolelectric sensors use lasers, which emit more coherent beams that scatter less and maintain their brightness over a distance. (see also the related link)
