Abstract
An atmospheric moisture measuring system is provided that includes at least one moisture collector, at least one moisture sensor, at least one heater and at least one timer system. The at least one moisture collector is coupled to receive an airflow from a bleed system of a vehicle. Each moisture sensor is coupled to receive evaporated moisture from an associated moisture collector of the at least one moisture collector. Each heater is configured to heat an associated moisture collector to generate the evaporated moisture received by an associated moisture sensor. Each timer system is configured to selectively activate an associated heater.
Claims20
An atmospheric moisture measuring system comprising:
- at least one moisture collector coupled to receive an airflow from a bleed system of a vehicle;
- at least one moisture sensor, each moisture sensor coupled to receive evaporated moisture from an associated moisture collector of the at least one moisture collector;
- at least one heater, each heater configured to heat the associated moisture collector to generate the evaporated moisture received by the associated moisture sensor;
- and
- at least one timer system, each timer system configured to selectively activate an associated heater.
A system to measure moisture in an atmosphere, the system comprising:
- a first atmospheric moisture measuring system including,
- a first moisture collector coupled to receive an airflow from a bleed system of a vehicle,
- a first moisture sensor coupled to receive first evaporated moisture from the first moisture collector,
- a first heater configured to heat the first moisture collector to generate the first evaporated moisture received by the first moisture sensor, and
- a first timer system configured to selectively activate the first heater at a first phase of a set frequency;
- and
- at least one second atmospheric moisture measuring system including,
- a second moisture collector coupled to receive the airflow from the bleed system of the vehicle,
- a second moisture sensor coupled to receive second evaporated moisture from the second moisture collector,
- a second heater configured to heat the second moisture collector to generate the second evaporated moisture received by the second moisture sensor, and
- a second timer system configured to selectively activate the second heater, the second timer system operating at a second phase of the set frequency.
A method of measuring moisture in an atmosphere, the method comprising:
- collecting a sample of air from an airflow in a bleed system of a vehicle;
- turning on a heater for a select amount of time to generate evaporated moisture from the collected sample;
- and
- sensing a moisture level in the evaporated moisture with a moisture sensor.
