1 / 10 page ________________________________________________________________________________________ Humirel HTG3400 Series Datasheet / HPC124 Rev A November 2007 1 HTG3400 Series Compliant with RoHS regulations RELATIVE HUMIDITY AND TEMPERATURE MODULE Based on the rugged HUMIREL humidity sensor, the HTG3400 series are dedicated humidity and temperature plug and play transducers designed for OEM applications where reliable and accurate measurements are needed. Direct interface with a micro-controller is made possible with the modules humidity linear frequency and direct NTC outputs. The HTG3400 series are designed for high volume and demanding applications, where power consumption is critical. • HTG SERIES GENERAL CHARACTERISTICS Main Features Suitable for small bulk assembly Product free from Lead, Cr (6+), Cd and Hg. Compliant with RoHS Reliability not affected by repeated condensation Full interchangeability. Better than +/-3%RH and +/-0.25°C Demonstrated reliability and long term stability Humidity calibrated within +/- 3% RH @ 55% RH Temperature measurement through NTC direct output Ratiometric to voltage supply within the specified range HTG3400 Series are also available with a Humidity Linear Voltage Output : HTG3500 Series (HPC123_0) Maximum Ratings Storage Temperature Tstg - 40 to +125 °C Supply Voltage (Peak) Vcc 20 Vdc Humidity Operating Range RH 0 to 100 %RH Temperature Operating Range Ta -40 to +110 °C Maximum Output Current (Peak) I peak 3 mA Maximum Power Pd 10 mW Electrical Characteristics (@T=23°C, RL>1MΩ unless otherwise noted) Humidity Measuring Range RH 0 100 %RH Relative Humidity Accuracy (10% to 95%RH) ±3 ±5 %RH Temperature coefficient (10°C to 50°C) Tcc -0.05 -0.1 %RH/°C Recovery time after 150 hours of condensation t 10 s Humidity hysteresis +/-1 %RH Output impedance Z 50 Ω Sink current capability (RL_Min = 8 kOhms) (1) I 1 mA Warm up time tw 150 ms Constant Time (at 63% of signal) 33%RH to 75%RH (2) τ 5 10 s (1) Conditions of sink current: Vout + 0.054V (3%RH) at Vout = 0.600 V (Vout min) (2) At 1m/s air flow * Nominal resistance @ 25°C R 9.9 10 10.1 k Beta value : B25/50 B 3346 3380 3414 K Temperature measuring range Ta -40 85 °C Nominal Resistance Tolerance at 25°C Rn 1 % B value tolerance B 1 % Constant Time 10 s * Except for low temperatures OPERATING RANGE 0 25 50 75 100 -40 -20 0 20 40 60 80 100 TEMPERATURE IN °C Maximum Humidity of 250g/kg Peak Condition at 450g/kg |
