PENKO Engineering, Ede, the Netherlands, has introduced the Type SJB190 cable connection box which has been designed to avoid interruptions and interferences to the smooth running of plant processes. Every load cell, up to four per weighing system, is monitored individually. Deviations outside the preset tolerances are made visible on the display and reported via a potential-free contact.

On the front of the instrument there is a clear OLED display which is clearly visible under sunny conditions, together with control buttons. This allows fault finding by checking the measurement signal of each load cell separately by simultaneously comparing it with the average of all sensors and the excitation voltage. This allows the user to localise any problem immediately without searching whether, for example, a cable is broken, a load cell drifts or was overloaded. If necessary,  preventive action can be taken by replacing the defective sensor.

This intelligent connection box replaces the usual one, since no external power supply is required. The unit can be supplied optionally in a robust plastic (IP65) or stainless steel (IP66) housing, both suitable for wall mounting. www.penko.com
