This humidity sensor is of the electrolytic type and converts the measured ambient value into an impedance, which can then be electrically measured. Suitable for applications such as climate control household appliances, office and communication equipment, building automation, climate technology, air humidifiers, air dryers, etc.

• Through hole mounting
• Measurement range 20 to 95% RH @ 0 to 60°C
• Compact size
• No calibration required
• Excellent linearity
• High sensitivity
• Long-term stability

The robust, stable mounting bracket made from corrosion-resistant aluminium allows for installation on both walls and masts. All mounting holes are pre-cut, which simplifies the installation. The setting angle ensures reliable detection and short drying times. All mounting screws are located outside of the interior, meaning that leak-tightness is guaranteed. The cable can be fed out either at the lower front side or from underneath.

• Suitable for use with the B+B Sensors CON-REGME 24 V 24 V Rain Detectors (50-3708 and 50-3079)
• All installation parts included
• Installation instructions provided

This industrial standard humidity probe is designed to fit discreetly into a wall mounted housing. To measure relative humidity a precise and stable polymer capacitive sensing element is used. For temperature measurement, the sensor uses a Platinum sensor that converts the measured temperature into a standard signal output. The sensor is capable of continuous use and the linearised and temperature compensated measurement has high long-term stability. Application areas include building automation, industrial measurement and control technology, air-conditioning and drying technology.

• Protection against overvoltage and transients
• AC/DC Power supply
• High accuracy
• Latest sensor technology and innovative ASIC design

HYT 271 – the powerful allround talent of the HYGROCHIP product series Mechanically robust, chemical resistant and dew formation resistant, this digital humidity sensor with only 10.2 x 5.1 x 1.8 mm size offers the widest application window and an optimal price performance ratio. Precisely calibrated, the HYT 271 delivers an accuracy of ±1.8 % rH and ±0.2 °C - ideal for sophisticated mass applications, industrial handheld devices and precise humidity transmitters. Like all representatives of the HYGROCHIP family, the sensor combines the advantages of a precise, capacitive polymer humidity sensor with the high integration density and functionality of an ASIC. The signal processing integrated in the sensor completely processes the measured data and directly delivers the physical parameters of relative humidity and temperature over the I²C compatible interface as digital values. The module is precisely calibrated by the manufacturer and is therefore fully interchangeable without adjustment. Both the linearity error as well as temperature drift are corrected “OnChip” through computation resulting in an outstanding accuracy over a wide range of application. The high chemical resistance, dew formation resistant design and an excellent long term stability speaks for itself.
