Patent number: 7740402Abstract: A detector and a method for determining the presence of a fluid are disclosed. The detector comprises a probe having a thermistor with the probe being arranged to be exposed to a fluid and to allow thermal flow between the thermistor and the fluid, a temperature sensor for measuring the temperature of the thermistor and a controller. The controller is arranged to supply electrical power to the thermistor when it is below a predetermined temperature to heat it up and to turn off the supply of electrical power to the thermistor when it is at or above the predetermined temperature. The presence or identity of a fluid exposed to the probe is determined based on the proportion of time that power is supplied to the thermistor to maintain it substantially at the predetermined temperature.Type: GrantFiled: September 2, 2008Date of Patent: June 22, 2010Assignee: General Electric CompanyInventor: Philip George Camp
