Nolta GmbH
The NIVA level controller KR 1 electronic Ex was designed especially for use in intrinsically safe electrical circuits in potentially explosive atmospheres according to ATEX 95. In accordance with license SEV 06 ATEX 0137 the level controller KR 1 electronic EX may be used in zones 1 and 2 as well as in gas groups IIA, II B and IIC, where exists an explosion hazard due to combustible materials in temperature classes T1 to T6. The controller is equipped with a change-over contact (SPDT), meaning that depending on the electrical connection, the level controller can be used both to empty and fill a tank. Unlike level controller MS 1 electronic EX, type KR 1 electronic EX is a wide angle controller, which means that only one controller is required for switching on and off.
