Presentation

The Det-Tronics family of catalytic combustible gas sensors provide unmatched flammable gas detection performance in harsh environments and challenging conditions.

The heart of the catalytic sensor consists of a pair of computer matched pellistors (beads) that provide identical electrical resistance in clean air. When flammable gas is present, the active bead catalyzes the combustible gas molecules, while the inactive (reference) bead balances the reaction and compensates for normal changes in the ambient environment. The sophisticated design and construction of Det-Tronics catalytic sensors provides excellent sensitivity, response time, and resistance to physical shock and vibration.

All Det-Tronics catalytic gas sensors are poison-resistant, and are constructed with a one-piece 316 stainless steel housing. Other features include an integral thermal barrier to prevent bead interaction, and a sinter bonding technique to ensure superior protection against electromagnetic interference. All sensors are provided with a laser etched identification and approvals label that will withstand exposure to harsh outdoor industrial environments.

The CGS can be used for detection of virtually all combustible and flammable gases, including hydrogen, and is compatible with the FlexVu® UD10, Infiniti® U9500, Model 505 transmitter, EQ22xxDCUEX, and STB.
