Enabling rockets and aircraft to accurately measure temperature and humidity.
This advanced temperature and humidity sensor uses laser-trimmed thermoset capacitive and silicone band-gap sensing technology to deliver highly accurate measurements. Used in military aircraft, commercial aviation, and space launch systems, the lightweight and rugged sensor is engineered to perform reliably under pressure and in vacuum environments.
SV-HAT
| Feature | Specification |
|---|---|
| Input Voltage Range | 18 to 36 V DC |
| Power consumption | 150 mW The power supply inputs are galvanically isolated from the outputs. This will allow the analogue outputs to float with respect to system ground, to avoid earth loops |
| Pressure range | 0 to 60 bara |
| Storage temperature | 0 to 100% RH |
| Weight | 89g / 3.1oz |
| Enclosure material | Aluminium sensor enclosure - Anodised black Amphenol MIL-DTL-38999 Series III connector - nickel coated aluminium |
Humidity Measurement
| Feature | Specification |
|---|---|
| Measurement range | 0 to 100 %rh |
| Measurement accuracy | ± 3.0 %rh over 10 to 90% RH range (@25 °C). Up to ± 4% RH over entire operating range (@25 °C) |
| Measurement resolution | 0.2% RH |
| Measurement drift | < 0.5% RH/year |
Temperature Measurement
| Feature | Specification |
|---|---|
| Measurement range | −10 °C to 50 °C (14 °F to 122 °F) |
| Measurement accuracy | ± 0.3 °C over 5 to 50 °C range. Up to ± 0.5 °C over entire operating range |
| Measurement resolution | 0.1 °C |
| Measurement drift | < 0.04 °C/ year |
Output Interfaces
| * One analogue output each for temperature and humidity measurements |
|---|
| * 1 to 5 V DC linear output |
| * Fault indication via analogue output indicated by output of less than 0.5 V |
| * Each output is galvanically isolated from the input supply, but not from each other. |
