Kelco KP-10 Highly Accurate SPDT 3-Wire Probe Level Switch with 10m of Cable
Kelco KP Series Highly Accurate Probe Level Switch with 10m of Cable
| DOWNLOAD DATA SHEET | DOWNLOAD INSTALLATION |
The Kelco KP Series Probe Level Switch is a compact, highly accurate, and repeatable single-point liquid level sensing solution designed for reliability in harsh environments. Constructed from UPVC and polypropylene with a vented heavy-walled float chamber, it has no external moving parts and is safe for potable water, containing no mercury or lead.
A magnetically coupled SPDT 3-wire reed switch provides stable, repeatable switching action with minimal liquid level change (5mm), making it ideal for applications where precision and reliability are critical. Rated for low-voltage signalling only, the KP is perfect for PLC, BMS, telemetry, and hazardous area installations when isolated with an intrinsically safe barrier.
Supplied with 10 metres of heavy-duty CPE cable, the KP Series is suitable for use in water, seawater, most acids and alkalis, and operates in bores, wells, tanks, bilges, and chemical storage vessels.
