General specifications | |
|---|---|
| Function principle | limit detection Maximum or minimum detection in tanks or pipelines containing all types of liquids including use in explosion hazardous areas. Particularly suited to very aggressive liquids thanks to high degree of corrosion protection. |
| Measuring method | The forks of the sensors vibrate at their intrinsic frequency. This frequency is reduced when covered with liquid. The change in frequency then activates the limit switch. |
| Construction type | device with extension tube |
Supply | |
| Rated voltage | electronic insert FEL50A (PA): 9 ... 32 V DC electronic insert FEL51 (AC): 253 V AC, 50/60 Hz electronic insert FEL52 (E5): 10 ... 55 V DC electronic insert FEL54 (WA): 19 ... 253 V AC, 50/60 Hz or 19 ... 55 V DC electronic insert FEL55 (SI): 11 ... 36 V DC, PLC electronic insert FEL56 (N1), FEL58 (N2): isolating amplifier acc. to EN 60947-5-6 (NAMUR) |
| Current consumption | electronic insert FEL52 (E5): max. 15 mA |
Electrical specifications | |
| Surge protection | electronic insert FEL51 (AC), electronic insert FEL52 (E5), electronic insert FEL54 (WA), electronic insert FEL55 (SI): overvoltage category III |
Input | |
| Switching point | see section switch point |
| Measured variable | limit level (limit value) |
| Measurement range | depends on mounting point and pipe extension up to 3000 mm , larger sizes on request |
Output | |
| Switching delay | when fork is covered: approx. 0.5 s, when fork is exposed: approx. 1.0 s (other switching times on request) additionally configurable for PROFIBUS PA (electronic insert FEL50A (PA)): 0.5 ... 60 s |
| Switch behaviour | switch-over for minimum/maximum residual current safety on electronic insert MAX = maximum safety: The output switches to the power fail response when the fork is covered. for use with overspill protection for example MIN = minimum safety: The output switches to the power fail response when the fork is exposed. for use with dry running protection for example When switching on the power supply the output assumes the alarm signal. After max. 2 s it assumes the correct switching mode. |
