The TGAES hydrocarbon gas detector is an open path infrared gas detection system that provides continuous monitoring of combustible hydrocarbon gas concentrations in the range of 0 to 1,5 LEL/m, 0-2,5 LEL/m, 0-5 LEL/m, over a distance of 5 to 200 meters. Standard system outputs include 4-20 mA DC current output, with HART and RS-485 MODBUS communication. TGAES is capable of detecting most hydrocarbon gases and vapors including methane, ethane, propane, butane, propylene and others. No direct electrical interconnection between the two modules is required. The application of the TGAES system is allows to substitute for up to 12 fixed gas detectors. The TGAES system consists of two stainless steel modules- a transmitter and a receiver, along with mounting fixture hardware. Both modules are powered from an external 24 volt DC supply. The receiver provides the measurement signal outputs, and is furnished with an onboard “status indication” LED and an external magnetic bangle for reset setting and zero adjustment. The transmitter contains one ultra-reliable xenon flash lamp. Both modules are installed of approximately the same elevation and must be aligned to point directly at one another. The TGAES transmitter module illuminates a direct linear path ending at the TGAES receiver module. As flammable hydrocarbon gases intersect the light beam between by the two modules, certain IR wavelengths are absorbed by the gas, while other IR wavelengths are not. The amount of IR absorption is determined by the concentration of the hydrocarbon gas. A pair of optical detectors and associated electronics located in the receiver module measure the absorption. The change in the intensity of the absorbed light (active signal) is measured relative to the intensity of light at a non-absorbed wavelength (reference signal). The microprocessor computes the gas concentration and converts the value into a 4-20 mA current output signal (digital signal), which is then communicated to external control and annunciation systems. No filter wheel motors or other moving parts are utilized in either module.
