Position sensors measure plant growth rates.
How do you monitor water stress in a strawberry plant?
This was one problem addressed by ADAS ­ the leading
consultancy and research organisation to the land-based
industries.
When they started on a project to measure the effects of growing
environments on the flavour quality of a strawberry. One of the key
criteria was to measure, on a minute-to-minute basis, the changes
in water status of a plant.
RDP had the solution with its SensaGap range of non-contacting
position sensors. SensaGap uses a capacitive measurement
technique to measure small variations in the thickness of the
strawberry runner, so there is no direct contact needed with the
delicate fruit. In addition, SensaGap can be used in harsh conditions,
even in the strawberry fields of the West Midlands!
