GDC-150
Gas Sensor Transmitter
The all new GDC-150 transmitter from Bacharach offers detection and protection for a wide range of hazards
including toxic gases such as carbon monoxide (CO), oxygen depletion, combustible gases, refrigerant leaks and
total volatile organic compounds (TVOCs). Analog interfaces allow the transmitter to be connected back to
Bacharach’s GDA Series of controllers (or any other gas detection controller), building management systems or
control systems. The GDC-150 features 4-20 mA or 0-10 VDC linear output signals, an automatic thermal resetting
fuse, RoHS compliant circuit boards and LED indicators for power and open loop.
The onboard alarm LED’s indicate when alarm threshold values are exceeded. The unit can be ordered with an
optional alpha numeric LED display that shows gas concentrations in real time while alarm relays alert personnel
of potential dangers, avoiding incidents and potential hazards.
The GDC-150 is packaged in a rugged, polycarbonate housing for both indoor and outdoor applications. When
leaks occur, the GDC-150 sensors respond quickly and accurately to protect people and property. Automated
calibration and simple maintenance procedures performed in the field allow for continuous operation and
assurance that areas are monitored and protected at all times.
