Compact Level Gauges
SNKK Series

|
Characteristics / Materials Visual / electrical fluid level indication in hydraulic reservoirs
- Ideal for all areas of application in which space is limited: compact design and space-saving installation
- 40mm shorter in comparison with level gauge SNK with plug according to industry standard DIN EN 175301-803-B/ISO6952
- Protection class IP67 (IP69K on request) enables the use of the SNKK even under rough conditions (e.g. for construction, forestry and agricultural machinery) and also cleaning with a high-pressure washer
- Equipped with plug M12 according to IEC-61076-2-101 and with a changeover switch as delivery standard
- Also available with dial thermometer with probe, with thermo switch or with temperature sensor and a display unit
