Heated humidity sensor HMC03M

relativehigh-sensitivitymeteorological

Product Details HMC03M is optimised for short response time even at very low temperature in the upper atmosphere. It combines on a silicon substrate a capacitive relative humidity sensor and a heating resistor (heater). The heater is dedicated for fast recovery of the humidity sensor after condensation or icing. This leads to outstanding measuring performance in high-end weather observation. - Very short response time even at low temperature - Fast recovery after condensation or icing due to sensor heating - High sensitivity and outstanding linearity Technical Specifications - Nominal capacitance C0 (at 30 °C / 86 °F): 120 ± 40 pF - Sensitivity (for C0 = 120 pF, in average): 0.41 pF / % RH - Response time t63 (see Graph for details): - < 8 sec. at -30 °C (-22 °F) - < 11 sec. at -40 °C (-40 °F) - Working range temperature: -80...60 °C (-112...140 °F) - Working range humidity: 0...100 % RH - Linearity (0...98% RH): < ± 2 % RH
