5 Different switch technologies
Vibration, Capacitance, Microwave Barrier
Vibration Switches
Liquids and solids VEGASWING VEGAWAVE VEGAWIB Plug and play
VEGASWING - Vibration switch
Vibration Switch
1200 Ghz - Piezo drive - if SG = 0.5 or lighter forks won’t respond. Look for frequency being damped. For liquids
VEGAVIB - Vibration switch
Vibration Switch
350 Hz. Look for amplitude being damped
For granular solids. Carbocer coating (reduces dust).
Detection of solids under water. Can do level under waver (point level no continuous)
VEGAWAVE - Vibration switch
Vibration Switch
200 Hz. Look for amplitude being damped
Detection of solids under water.
Can do level under waver (point level no continuous)
Tight spaces no approvals
VEGASWING 51
VEGASWING 63
Ammonia - endless length up to 6 meters
Microwave Barrier Switch
Liquids and solids sentitivity adjustment time delay for falling product works just like radar high temperature option available PULS 62 basically - 26 GHz ceramic on one end level detection independent of the medium
VEGAMIP
Anything you do with a PULSE 62 you can do with VEGAMIP. Set up is done in the receiver VEGAMIP T61 Emitter - needs power VEGAMIP R 61 Receiver - needs power VEGAMIP R 62 High temps and abrasive
Capacitance Switches
Liquids and solids Conductive and non conductive options monitors change in standing capacitance requires set up in actual use (must see product) once set up very repeatable sticky products - very good!
VEGASWING 66
High temperatures High Pressures -196 C to 450 C temperature distance piece inconel 718 material on forks inductive drive second line of defense (ceramic)
Capacitance
The ability of a body to hold an electrical charge and the amount of that charge is measure in picofarads
Conductive limit switches - no approvals
Liquids
Switch point adjustment - rod/cable length
point level indication
VEGASWING series 50
Vibration point level switches for liquids
VEGASWING 51 = compact (not good with sticky products)
VEGASWING 53 = extended up to 1m Not continuous LED like the VEGA POINT 3 individuals LEDs depending on switch estate - red, yellow, green No bluetooth can not configure IO link available
VEAPOINT series 10,20,30
VEGAPOINT 10 and 20 = Liquids
VEGAPOINT 30 = solids
PNP for transistor connection
Switch the plus on the output
PNP = sourcing
NPN for transistor connection
Switch the negative on the output
NPN = sinking
NO equals MIN
Normally open you have o volts then when it hits the setpoint then you have 24 volts
NO=MIN (OUT 2)
NC equals Max
Normally closed you have 24 volts then when it hits setpoint then you have 0 volts
NC = MAX (OUT 1)
VEGAPOINT 21
Water based media (more than 10% water)
& oils and sticky media
VEGAPOINT 31
Bulk solids
Difference between VEGAPOINT 21 & VEGAPOINT 31
Factory programming
21 set up for liquids
31 set up for solids
You can use 31 to measure liquids and 21 for solids - this is just for customers when ordering online
VEGAPOINT series 10
Can be used in 100C (212F environment) ultra compact no adjustment No Bluetooth only threaded connection light ring is output
VEGAPOINT series 20, 30
Can be used in 115C (239F environment)
Adjustable with PACTware the VEGA Tools app or IO-Link
version with extended switch point up to 3ft
includes temperature sensor - you can look up process temperature
ISO 4400 Available
