Capacitive Humidity Sensor Optimal for weather balloons / radiosondes with on-chip heater and temperature sensor Extraordinary fast response time: 3 x faster than P14 Rapid Humidity sensor with on-chip heater / temperature sensor Outstanding sensitivity Temperature shock resistant High humidity stability Fast recovery time after condensation Customer-specific sensor available upon request Robust against icing 1) For actual size, see mechanical dimensions Technical Data Back side: Heater / temperature sensor Front side: humidity sensor Operating humidity range: Operating temperature range: Heater / temperature sensor:* IEC60751 ±1%: ±(2.59 + 0.05 x |T|) °C |T| = absolute value of temperature in °C Loss factor: Linearity error: 2) High accuracy temperature sensor on request 3) The response time is often measured for increasing humidity steps,whereas physics predicts that decreasing humidity leads to generally far longer response times for capacitive humidity sensors. IST AG thus measures response times always for decreasing humidity values, since this is the worst case. Measurement frequency range: Maximal supply voltage: Signal form: alternating signal without DC bias CuP-SIL wire post-plated with Sn, 10 mm W x H: 0.5 x 0.25 mm with 1.27 mm pitch * Customer-specific alternatives available DHP14-Rapid-2-Thermo_E2.3.1_preliminary | Humidity Sensor | P1
