Explosion-Proof Housings Questions
Are the BEX Series Explosion-Proof Housings UL Certified (Listed)?
Broadsight Systems’ BEX Series housings are UL Classified “enclosures for use in hazardous locations as to explosion and fire hazard only”. In order to be fully UL Certified (Listed), the complete system (e.g. housing + camera + lens + wiring) must undergo additional temperature testing by a certifying agency. Contact Broadsight Systems for assistance with obtaining a full listing.
Can I request customizations to the housing?
The housing itself cannot be modified. Broadsight Systems’ Customization program enables you to specify what equipment is required inside the housing. Our product design engineers will develop a CAD model of the complete package including any internal bracketry and wiring required for the system to operate. We can then supply you the customized package without or without the electronics installed. If obtaining a UL Listing for the system

How to Clean a Thermal Camera’s Germanium Lens
Use a lens tissue with a solvent (a dry lens tissue can scratch optical surfaces). A good solvent to use is a mix of 60% acetone† and 40% methanol. Acetone alone dries too quickly to dissolve all of the debris. The methanol slows the evaporation time, and also dissolves debris that acetone alone would not clean.
