These up to 4 W potentionmeters show that Ex potentiometers can be small and compact. The external dimensions are approximately the same as those of standard industrial potentio-meter enclosures. Central fixing in a single hole and the standard size of shaft have been includend. From the variety of resistors on the market we have chosen cemented wire-wound resistors and carbon film resistors and developed a standard-program range.The metal Ex d enclosures are tailored to the dimensions of the resistors and feature a standard 30 mm diameter. The potentiometers have been designed so that the stated nominal capacities can be fully exploited at temperature class T6 or T5 and be deployed in zones 1 and 2. The potentiometer is fitted into an enclosure that meets the requirements of an approved type of protection in conformance to IEC/EN 60079-0.
