Capacitive Liquid Level Switch
The capacitive liquid level switch detects material level in silos, tanks and containers using radio frequency capacitance technology. It offers adjustable sensitivity from 0.5 pF to 750 pF, 0–30 s delay, and SPDT relay output rated 5 A 220 VAC. Power supply is 220 VAC 50 Hz or 24 VDC; probe material SUS304/316 with PP or Teflon insulation for level alarm applications.
- Working Temperature
- -10–80℃ or -10–230℃
- Power Supply
- 220VAC 50Hz or 24VDC (24VDC is recommended)
- Relay Contact
- 1 set of SPDT, 5A 220VAC
- Induction Rod Material
- SUS304/316
- RF capacitance technology with anti-adhesion circuit eliminates false signals from buildup.
- Adjustable sensitivity 0.5pf–750pf and relay delay 0–30s.
- SPDT relay output 5A 220VAC for high/low fault alarm.
- Induction rod SUS304/316 with PP or Teflon insulation sheath.
- Probe installed horizontally should be inclined 20° to reduce material impact.
