A feature of the IKAVISC equip-ment system have been combinedinto one unit. The twist in the torsionbar is used to convert into an actualtorque readout through the elec-tronic measuring system. The signalsfrom the torque sensor are processedand a readout given on the largedigital display.
In addition to a measuring mode, theversatility of the IKAVISC equip-ment is extended with its ’limit’alarm feature. Two alarm settings.can be selected. An optimum ’limit’can be selected, as can an upper orlower value. When either the upperor lower limit is exceeded an alarm
can be triggered. This alarm output,apart from giving an audible warn-ing, can be used to trigger valves etc.,in such applications as batching.

An inert gas blanket for the Linomat IV protects oxia-t-ion-prone samples or theircomponents against attack by atmospheric oxygen while being sprayed on. The stream ofnitrogen propelling the sample will not, on its own, protect sensitive substances. By a kind ofwater-jet pump action, the sprayjet sucks in air and hence oxygen molecules, which makeintimate contact with thejqnely dispersed spray mist and can react with substances sensitiveto oxidation. This is prevented if spraying on is effected under a blanket of nitrogen. Inaddition, during spraying on ofsuccessive samples, the starting zones ofthe samples alreadyapplied remain under inert gas protection.
