HygroPro User’s Manual

4.4 Moisture Sensor

Sensor Type

•

Thin-film aluminum oxide moisture sensor probe

Calibration

•

Each sensor is individually computer-calibrated against known 
moisture concentrations, traceable to 

NIST

Calibration Interval

•

Sensor recalibration at GE is recommended every six to twelve 
months, depending on the application

Flow Rate

•

Gases: 

Static to 100 m/s linear velocity at a pressure of 1 atm.

•

Liquids: 

Static to 10 cm/s linear velocity at density of 1 g/cc

4.5 Built-In Temperature Sensor

Type

•

Nonlinear NTC thermistor (resultant temperature linearized by 
microprocessor)

Measurement Range

•

–22° to 158°F (–30° to 70°C)

Accuracy

•

±0.9°F (±0.5°C) overall

Response Time (Maximum)

•

One second in well stirred oil, or 10 seconds in still air, for a 63% 
step change in increasing or decreasing temperature
