User Guide for SRAQ-G208
Product Description
The SRAQ-G208 gas transmitter detects the presence and concentration of liquefied petroleum gas as well as liquefied natural gas. Integrated
circuitry produces a non-linear voltage signal corresponding to the gas concentrations. With high sensitivity to butane, propane and methane, the
SRAQ-G208 has a detection range of 300 to 10000 ppm. It is well suited for detecting LPG and LNG leaks and triggering alarms.
Features

  • Page 3 Electrical Diagram 24V and GND are the power interface, D1 is the power indicator. Aout is the analog output interface, VR2 is the signal trimmer potentiometer. VR1 is the magnification (the output of 0-5V and 0-10V can be adjusted freely through this potentiometer). The load resistance of the sensor composed of R7 and RP2 potentiometer is in parallel relationship (can be changed by user).
