Measuring gap heating
The Gap Conditioning Device facilitates consistent temperature conditions for increased measuring accuracy.
Product Highlights
- Temperature control up to 250 °C
- Control accuracy +/- 1 °C
- Protection class IP65
Customer benefits
- Defined temperature in the measuring gap
- Increases measuring accuracy
- Simultaneously cleans the measuring gap
- Prevents development of condensate
The Gap Conditioning Device GCD blows heated air into the measuring gap to reach the defined temperature. The temperature of the heating air can thereby be adjusted with a precision of 1 degree. The measuring gap is cleaned and kept clean at the same time by the steady flow of air. The air pressure of the heating air can be set with a pressure gauge.
The Gap Conditioning Device GCD is an optional add-on device for the respective measuring sensor used. It is installed in the running direction of the product upstream of the actual measuring sensor to thereby heat the measuring gap with the product running direction.
Air can be heated and the heating air temperature controlled with the Gap Conditioning Device GCD. Cooling is not possible with this device, even if lower temperatures than the ambient temperature can be set on the temperature controller. The minimum temperature depends on the ambient temperature and the temperature of the supplied compressed air. The temperature control of the heating air is factory set and limited to 250 °C; it is preset to 100 °C.
Prevention of condensate
Because of the usually high temperature differences between product, room air and measuring equipment, the moisture in the room air often condensates since the dew point lies within the measuring gap. The measuring windows fog up from the condensate which may lead to wrong measuring results. The Gap Conditioning Device GCD prevents the formation of condensate through the temperature compensation in the measuring gap.
