The LevelSwitch is available in 4 different models:
- CV120 standard model with fix insertion length of approx. 170mm
- CV130 model with welded pipe extension, insertion length up to 2,0m
- CV140 model with threaded pipe extension, insertion length up to 4,0m
- CV150 model with cable extension, insertion length up to 20m
CV120 / CV130 / CV140 / CV150 are excellent working level control
devices for detecting high-, low- or mid level in silos, vessels or
hoppers filled with dry grained or powdered material. Over and above
all the positive characteristics of the vibration technique itself the LevelSwitch-series offers the following advantages to the user:
Maximum versatility
- high sensitivity: even very light materials with densities down to 20 grams/litre can be detected
- strong stainless steel construction with patented reinforced membrane allows to use the LevelSwitch as well for heavy materials like cement and in rough environments
- applicable for powders as well as for materials with grain size up to 40mm
Highest performance
- the unique design with the single diamond shaped vibrating blade makes the LevelSwitch work reliably without malfunction; the single blade design has the advantage that material cannot build a bridge over the two blades of instruments with fork design thus causing false alarms; also materials cannot be squeezed between the two blades
- the diamond shape helps that material can easily flow over the vibrating blade and prevents material build-up causing false signals
Highest quality
- the complete probe is made out of stainless steel, the electronics is mounted inside an aluminium enclosure, protection IP66 / IP67
- developed and manufactured at PTL in Germany according to DIN EN ISO9001:2015
- all units are CE-certified and meet the requirements of European directives LVD 2014/35/EU and EMC 2014/30/EU
- ATEX approvals for dust-ex and gas-ex applications available for CV120, CV130 and CV150
