H(T)U(F) 3500 Humidity & Temperature Transducer
Brand: American Sensor Technologies IncH(T)U(F) 3500 Humidity & Temperature Transducer
Brand: American Sensor Technologies IncBased on the new humidity sensor HTU21P, HTU3500 Series are dedicated humidity and temperature plug and play transducer 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 voltage and direct NTC outputs. The HTU3500 Series are designed for high volume and demanding applications where power consumption is critical.
Optional PTFE filter/membrane (F) protects HTU3500 Series modules Analog humidity modules with temperature output against dust, water immersion as well as against contamination by particles. PTFE filter/membrane preserves a high response time. Several connectors are proposed. 5 Vdc or 3 Vdc power supply products are available.
Features- Full interchangeability with no calibration required in standard conditions
- Instantaneous desaturation after long periods in saturation phase
- Analog output
- Demonstrated reliability and long term stability
- Reliability not affected by repeated condensation
- HU3500 - Analog humidity sensor only - can be proposed
