Kobold’s level switch - KAL-L Orange takes Gold at 2012 Olympics

KOBOLD Instrumentation, represented in South Africa by Instrotech – a Comtest Groupcompany – develops, manufactures and sells instruments for monitoring,measuring and regulating the physical quantities of flow through pressure,level and temperature.

CASE STUDY
Kobold was approachedby a company specialising in automation to provide flow switches for thedistrict heating system for the competitor`s village constructed for the 2012London Olympics. They required scores of flow switches for different pipe sizesand for temperatures up to 95°C. After initial discussions on whether to use apaddle type or thermal type switch, a thermal (calorimetric) type was chosen. Acustomised probe length was offered as the best size to standardise on so oneunit would be sufficient for all applications; thereby simplifying logistics.All units were high-temperature specification, again for standardisation.Kobold also designed a special extension between the connection on the probeand the terminal box so that the terminal box stood clear of the 100 mm ofinsulation around the pipes; making it a truly custom device. Initially therewas some concern that, as the pipes were covered in 100mm of insulation, giventhe high temperatures of the application, the compact design of the unitsoffered would mean that they would over-heat. In effect, the insulation wouldmean that the terminal box of the units would experience the majority of theapplication temperature which could be as high as 95°C and would be unable todissipate that heat leading to thermal shut-down of the electronics. Toovercome this concern, Kobold offered a customised extension between theconnection to the pipe and the terminal box so as to elevate it above the levelof the insulation; thereby allowing it to be in ambient temperature air. Thiscustomised design was an Olympic winner and a major factor in winning over thecustomer.
