What are the recommended power requirements for a Pellistor sensor?
2024-07-30 - 技术问答 See individual datasheets. The sensors are run in a Wheatstone bridge circuit either in constant voltage or current mode.
What are the recommended storage conditions for a Infrared sensor?
2024-07-30 - 技术问答 Sensors are not sensitive to storage temperature. See individual datasheets.
How to Check VDE Certification for TNR™ Ceramic Varistors
2024-08-30 - 技术问答 Details about VDE certification can be found on the VDE website which you can reach by following the link below acquired safety standards on each individual product page.(https://www.vde.com/tic-en/marks-and-zertificates/vde-approved-products/search)
Can Pellistor sensors withstand exposure to the target gas for long periods?
2024-07-30 - 技术问答 This depends on the level and duration. The longer and higher the concentration, the greater the degree of zero drift and change in (net) sensitivity. The latter is usually a decrease in sensitivity.
