© Siemens AG 2016 Level Measurement Point level measurement - Vibrating switches SITRANS LVS100 ■ Overview ■ Configuration Installation Rigid extension with sliding sleeve Position tines vertically to avoid product build-up: use a 50 mm open-end wrench to turn the process connection until the tine orientation marking faces up or down. L * Protection in case of high material loading. O 4 Cable gland faces downward to avoid water penetration. SITRANS LVS100 is a vibrating point level switch for material detection in bulk solids. ■ Benefits Tine orientation marking facing sideways. • High resistance to mechanical forces • Sliding sleeve options for adjustable insertion length and ease of cleaning • Rotatable enclosure for ease of installation and wiring • Suitable for point level detection of materials starting at a bulk density of 30 g/l (1.9 lb/ft3) • Customer desired extensions up to 4 000 mm (157.48 inch) ■ Application SITRANS LVS100 detects high, low or demand levels of dry bulk solids in bins, silos or hoppers. SITRANS LVS100 has a compact design and can be top, side, or angle mounted. The vibrating fork design ensures the tines are kept clean. The unique design of the fork and crystal assembly eliminates false high level readings even if tines become damaged. A signal from the electronic circuit excites a crystal in the probe causing the fork to vibrate. If the fork is covered by material, the change in vibration is detected by the electronic circuitry which causes the relay to change state after a one second delay. When the fork is free from material pressure, full vibration resumes and the relay reverts to its normal condition. • Key Applications: dry bulk solids in bins, silos, hoppers 4/104 Siemens FI 01 · Update 05/2016 Use angle mounting for flowing material only. If angle mounting is required with high material loading, customersupplied protection from falling material must be in place. * max. deviation from vertical O max. length L 5° 4.0 m 45° 1.2 m > 45° 0.6 m SITRANS LVS100 installation, dimensions in mm (inch) © Siemens AG 2016 Level Measurement Point level measurement - Vibrating switches SITRANS LVS100 ■ Technical specifications Design Mode of Operation Measuring principle Vibrating point level switch Input Measured variable High, low and demand Measuring frequency 200 Hz Material • Enclosure • Thread 1¼" NPT [(Taper), ANSI/ ASME B1.20.1], R 1½" [(BSPT), EN 10226] • Thread R 1½" [(BSPT), EN 10226], ½" NPT [(Taper), ANSI/ASME B1.20.1], sliding sleeve [min. length 500 mm (19.69 inch)] • Thread material: stainless steel 304 (1.4301) or 316L (1.4404) depending on configuration Tine material Stainless steel 316L (1.4404) Degree of protection IP66/Type 4/NEMA 4 Conduit entry 2 x M20 x 1.5 or 2 x ½" NPT Weight Standard version, no extensions: approx. 1.7 kg (3.7 lb) Power supply • 19 ... 230 V AC, +10 %, 50 ... 60 Hz, 8 VA • 19 ... 40 V DC, +10 %, 1.5 W Certificates and approvals • • • • • • Output Relays DPDT relay Relay delay From loss of vibration: approximately 1 second From resumption of vibration: approximately 1 ... 2 s Signal delay Probe uncovered to covered: approximately 1 s Probe covered to uncovered: approximately 1 ... 2 s Relay fail-safe High or low, switch selectable Alarm output Relay 8 A at 250 V AC, non-inductive Relay 5 A at 30 V DC, non-inductive Sensitivity High or low, switch selectable Rated operating conditions Installation conditions • Location Indoor/outdoor Epoxy coated aluminum Process connection CSA/FM General Purpose CE CSA/FM Dust Ignition Proof RCM ATEX II 1/2 D IECex Ambient conditions • Ambient temperature -40 ... +60 °C (-40 ... +140 °F) • Installation category III • Pollution degree 2 Medium conditions • Process temperature -40 ... +150 °C (-40 ... +302 °F) • Max. threaded bushing temperature 60 °C (140 °F) • Max. enclosure surface temperature 90 °C (194 °F) (Category 2D) • Max. extension surface temperature 150 °C (302 °F) (Category 1D) • Pressure (vessel) Max. 10 bar g (145 psi g) European Pressure Directive 2014/68/ EU: Category 1 Minimum material density Approx. 30 g/l (1.9 lb/ft3) Siemens FI 01 · Update 05/2016 4/105 4 © Siemens AG 2016 Level Measurement Point level measurement - Vibrating switches SITRANS LVS100 Selection and Ordering data Article No. Selection and Ordering data SITRANS LVS100, standard Vibrating point level switch for high or low level detection of bulk solids.
