Capacitive electrodes type EK, EL and VEGACAP are used for reliable continuous level measurement or level detection of solids and liquids based on the capacitive principle.
Operating Principle:
CapacitiveFeatures:
Reliable Repeatable Measurement
- Integral compensation of the standing capacitance
- Processing even of smallest capacitance changes
- Hysteresis free even with very adhesive, conductive products
- Level measurement even with varying product moisture (up to 15 %)
Easy Set-up
- without adjustment and/or filling
- On electrode EL – Signal conditioning instrument in the control room – PC via adjustment software VVO – HART ® -handheld – Directly on electronics (4 … 20 mA)
Simple to Service
- Test switch for level simulation
- Plug-in standard electronics
Application:
They can be used in applications where levels are detected as a two wire “ON-OFF” signal (4mA for OFF & 20mA for ON) in any installation position (vertically from top and bottom or horizontally). Whether in foods, chemicals, wastewater, stone crushers, cement or plastic production, hey ensure a continuous production process in tanks, silos and vessels anywhere within the process.
Specification:
Economic Installation
- 4 … 20 mA “ON-OFF” compact electronics (loop powered)
- Universal supply voltages 20 … 250 V AC/DC
- Over voltage protection as plug module integral or add-on
- For Ex-systems no potential equalization along the intrinsically safe line required
Rugged Construction
- Resistant electrode insulation
- Pressure ranges from -1 … +63 bar
- Operating temperatures from -50°C … +400°C
