Abstract
A portable gas analyzer includes multiple docking stations connected to a pneumatic flowpath through the gas analyzer. Modules are removably mounted to the docking stations. Some modules can be mounted at any one of the docking stations. The modules can include gas sensors and a microcontroller configured to generate data based on signals generated by the gas sensors. The modules are configured to simultaneously form each of electrical, mechanical, and pneumatic connections with the gas analyzer when mounted to the docking station.
Claims17
A handheld gas analyzer comprising:
- a housing;
- a gas inlet fluidly connected to a pneumatic circuit and a gas outlet fluidly connected to the pneumatic circuit, the pneumatic circuit disposed within the housing;
- a plurality of internal bays within the housing;
- a plurality of gas sensor modules, wherein a first subset of the plurality of gas sensor modules are configured to mount in the plurality of bays, each sensor module of the plurality of gas sensor modules comprising:
- a transducer for measuring a respective gas property;
- and
- programmable module circuitry configured to process signal information from the transducer and output data;
- an analyzer controller within the housing, the analyzer controller configured to receive the data output from the plurality of gas sensor modules;
- and
- wherein the pneumatic circuit runs serially through each of the plurality of gas sensor modules such that gas received through the gas inlet flows through each of the plurality of gas sensor modules between the gas inlet and the gas outlet.
