Working Principle

The operational principles of the UMQ-3066-D are based upon an advanced gas detection technology which utilizes a sensitive thermocouple and diaphragm displacement transducer to measure temperature, pressure, and concentrations of combustible gases within the surrounding environment. The instrument utilizes a three-stage detection system which uses a variety of sensor elements to measure the physical parameters of the surrounding environment.

The thermocouple is used to measure the temperature in the range of 0-120°C, while the diaphragm transducer is used to measure the pressure in the range of 0-80 psig. The device also incorporates a number of sensors to measure the concentrations of combustible gases in the atmosphere. These sensing elements measure the levels of oxygen, hydrogen, methane, propane, and other combustible gases and vapors in the atmosphere.

Once the raw data has been collected, it is passed through a signal processor which filters out any spurious signals and unnecessary noise. The processed data is then conveyed to an on-board digital display for control and monitoring purposes or optionally transferred to an external system via a digital link. As such, the UMQ-3066-D is a comprehensive and powerful instrument capable of measuring and controlling the physical parameters of the surrounding environment.
