Klingon Sensor Technology


Ever since Nilsson's invention of the open-chamber method in 1978, manufacturers have mounted the RH and temperature sensors along the central axis of the cylindrical measurement chamber.

Centrally mounted sensors (see left), have the following disadvantages:-

1. The sensors are prone to contamination. This is serious for the RH sensor, where surface contamination can cause loss of sensitivity, calibration and response speed.

2. The sensors are prone to mechanical mis-alignment, because they are held in place by weak connecting wires only. Misalignment during manufacture gives rise to inconsistent characteristics from probe to probe. Misalignment during use gives rise to flux calibration changes.


Recognising the vulnerability of centrally-mounted sensors, Biox explored the possibility of mounting them securely in the wall of the measurement chamber (see left). Through numerical modelling and experiment, Biox research established that wall-mounted Klingon sensors (Patent Application PCT/GB03/00265) could provide equivalent levels of performance, while eliminating the disadvantages of the traditional mounting.

Klingon technology enables consistent and reproducible manufacture of AquaFlux measurement heads, and this ensures consistent and reproducible characteristics from instrument to instrument. The protection from contamination afforded by the Klingon mounting ensures long-term stability and accuracy.
