Products Description
Det-Tronics 505 Combustible Gas Transmitter

Core Performance & Industrial Application
The Det-Tronics 505A3A2A1W is a 505 series combustible gas transmitter, adopting catalytic bead sensing principle. It converts flammable gas concentration into 4-20mA analog signal with HART digital communication, and works with matching gas controller to trigger alarm and interlock. It has fast response speed, stable anti-poisoning performance and explosion-proof enclosure, suitable for hazardous area classification. It can be equipped with local indicator and supports on-site calibration and parameter configuration, widely used for combustible gas leakage warning in petrochemical and oil & gas industries.
