Det-Tronics TXL Series Gas Transmitter - Manual (Page 3)

APPLICATION
The TXL family of detectors provide cost-effective gas
detection using a reliable electrochemical sensor.
Detector output is a two-wire loop-powered 4-20 mA
analog signal. The output signal is compliant with
industry standards and can be routed to any standard
4-20 mA analog input receiver or controller. An eight
character alphanumeric LCD display indicates the gas
type and concentration in PPM. All electronic circuitry is
contained within an epoxy-coated aluminum enclosure
with NEMA 4 rating Non-intrusive calibration is easily
performed by actuating a magnetic reed switch with a
hand-held magnet.
TXL detectors are intended for life safety protection in
hazardous applications including petrochemical, gener-
al industrial, municipal, and commercial facilities. The
TXL product family provides extremely low power con-
sumption, and can be installed with or without zener
diode barriers depending upon installation area require-
ments.
