Humidity Detectors

The EV514 ed EV515 humidity detectors are new precision electronic devices that measure the ambient humidity and give a linear analog output signal in the 10 - 90% relative humidity range. These detectors are suitable for all the cases where the ambient humidity must be continuously monitored with the possibilty to send a remote electric signal. The associated electronics provide for linearizing of the output signal and for the thermal drift compensations to hold the measure error within few %.

Advantages

• precision of the measure
• rapid respons
• hysteresis free
• linear output signal
• low current
• long life
