LCL2

کلید سطح خازنی پپرل فوکس، مدل LCL2.

مشخصات فنی

• Measuring method: A metal plate at the end of the probe, within the insulation, and the surroundings (e. g. the silo walls) combine to form the two electrodes of a capacitor. If the probe is covered or free of material, then the capacitance changes and the LCL switches.
• Construction type: device with rope probe
• Operating mode: MAX = maximum safety:; The device switches if the probe is covered or if the supply voltage is disconnected in a safety-oriented manner (signal on alarm).; example application: overspill protection; MIN = minimum safety:; The device switches if the probe is uncovered or if the supply voltage is disconnected in a safetyoriented manner (signal on alarm).; example application: dry-running protection
• Rated voltage: electrical connection E5: 10.8 ... 45 V DC, short-term pulse on 55 V DC; electrical connection WA: 20 ... 235 V AC, 50/60 Hz or 20 ... 55 V DC
• Current consumption: electrical connection E5: max. 30 mA, reverse-polarity-proof; electrical connection WA: max. 130 mA
• Measured variable: limit level (limit value)
• Measuring range: dielectric constant ≥ 1.6
• Switch-on delay: correct switching after max. 2 s
• Output signal: connection E5: switching PNP, Imax = 200 mA; - overload and short circuit protection; - residual voltage at transistor at Imax < 2.9 V; connection WA: contact change-over, potential-free; - Umax = 253 V; - Imax = 4 A (AC); - Pmax = 1000 VA, cos φ = 1, Pmax = 500 VA, cos φ > 0.7
• Hysteresis: vertical 5 mm (0.2 inch)
• Switching time: approx. 0.8 s when covering and uncovering the sensor
• Process temperature: -40 ... 80 °C (-40 ... 176 °F)
• Medium pressure limits: -1 ... 6 bar
• State of aggregation: solids
• Bulk density: ≤ 200 g/l
• Ambient temperature: -40 ... 80 °C (-40 ... 176 °F); -40 ... 60 °C (-40 ... 140 °F) (Dust-Ex version)
• Degree of protection: IP66, NEMA 4
• Connection: gland M20; thread G1/2, NPT1/2
• Material: F14 housing: polyester PBT-FR; F34 housing F34: aluminum; Probe: PPS GF40; probe rope: PE-HD; probe rope seal: VMQ
• Process connection: thread R1-1/2 acc. to EN 10226, BSPT; thread NPT1-1/2 to ANSI B 1.20.1
