SENMA Detector for Single Gas Component
Brand: madurSENMA is a flow gas sensor which serves as detector for single gas component. It is highly adaptable to specific needs. Depending on analyzed gas it uses NDIR (Non-Dispersive Infra-red), electrochemical, thermal conductivity or photoionization measurement technology. Each sensor is prepared for detection of particular gas and calibrated for required range. Gas sample gets to the sensor through the membrane pump, which is installed inside the device (note, Senma is not a diffusion sensor), then the gas is being analyzed. When concentration of detected gas exceeds specified level, SENMA sets off any connected alarm with help of the relay output or performs other, indicated action.
