The SMT Condensation Sensor is used to detect the presence of small amounts of water or ice by measuring the dielectric constant of the medium surrounding the sensor. The non-invasive sensor is perfect for monitoring condensation, frost, and moisture content levels in wood, concrete and stone.

Horizontal planar sensing elements couple to water ions through a fringing electric field. When condensation or frost forms on the sensing grid, the electric field passes through the ions, which act as the dielectric medium of the capacitor.

Capacitive moisture detection

Moisture monitoring in masonry
Sensor outputs linear voltage when in contact with condensation, frost, ice, snow, and/or rain.

Sensing element can be activated on either side of the sensor. Element on the top side is active by default.

Integrated thermistor and external bead thermistor available. External thermistor is used if temperature of a specific surface is required.

Mounting hole in centre of PCB.

Electronics are sealed and are suitable for outdoor monitoring.

Low profile allows the sensor to be inserted into a thin slot in masonry.

Compatible with SMT Industrial WiDAQ and A2/A3 data acquisition units.

Capacitance sensor element using SMT moisture detection tape is available. Calibration data has been developed for masonry moisture content monitoring.
Specifications

To connect to the ground bar, simply push the white/blue wire into the circular slot. To release a wire from the ground bar push a small slot screwdriver into the slot adjacent to the wire you wish to release, gently pull on the wire and it will be released. Any pin on the ground bar can be used.

Recommend using external thermistor if temperature is required (brown pair). The thermistor on the condensation sensor is not required for compensation, connecting the thermistor is optional.
