Det-Tronics CTX10A3N2T (014394-001) is a CTX10 catalytic combustible gas transmitter in an aluminum explosion-proof junction box. It works with one constant-current catalytic sensor to give a linear 0-20 mA signal for 0 to 100% LFL gas concentration, and is a direct field replacement for Det-Tronics Model 505 transmitters.
