Hygrometrix announces the first significant breakthrough in humidity measurement in over 20 years, with the HMX3000 series Hygrotron sensor that uses shear stress/strain hygrometry
Hygrometrix, a pioneer in humidity and moisture vapour, announces the first significant breakthrough in humidity measurement in over 20 years. The new HMX3000 series humidity transmitter uses a state-of-the-art commercially available ASIC to reduce part count, eliminate costly components and increase product reliability. The ASIC also provides integral 12bit to 16bit temperature measurement.

An integral EEPROM holds the calibration data for the ASIC.

The HMX3000 utilises the Hygrometrix Hygrotron sensor for maximum performance and reliability.

The real breakthrough is the Hygrotron sensor, which has numerous advantages over conventional humidity sensors including accuracy, ruggedness and sensitivity.

Part of the ruggedness is based on the sensor's similarity to a MEMS pressure sensor.

The sensor uses a proprietary and patented technique call shear stress/strain hygrometry to measure humidity.

This 'mechanical' method of converting humidity to voltage via a 4 arm Wheatstone bridge is immune to many of the failure modes that plague other types of sensor technologies.

The key performance advantages to this sensor are: 1.5% accuracy over the full range of 0-100%RH, excellent contamination resistance, immunity to failure modes common in capacitive or resistive humidity technologies, quick response time, low (2mA) power consumption, and broad operating temperature (-40 to 85C).

This is the first major breakthrough in humidity measurement technology in over 20 years.

The new transmitter has full digital calibration and no user adjustments or setup required.

The HMX3000-RH-420 is priced in single unit quantities at US$475.

Volume discounts are available.

Delivery is 4 weeks ARO.
