Sensor measuring systems for automation technology


Welcome to Sensor Instruments
"Sensor measuring systems for automation technology".


Precise inline monitoring for Ex and non-Ex areas

Our sensor-based measurement systems for spray jet monitoring enable reliable, non-contact detection of spray patterns in industrial processes. Depending on the application, solutions based on transmitted light or reflected light methods are available—both for use in hazardous (Ex) areas and in non hazardous environments. The systems detect spray quantity, intensity, geometry, and symmetry of the spray cone, making them ideally suited for demanding dosing, coating, and wetting processes.
 

Overview of the measurement systems:

Transmitted light measurement systems for spray jet monitoring (Ex area)
  • Single and multi channel systems with optical fibers for use in explosive atmospheres
  • Monitoring of spray cones via light attenuation in a laser or LED light curtain
  • Flexible fiber optic cross sections and attachment optics for variable measuring distances
  • Multi channel systems for detecting multiple spray jets or monitoring spray geometry
  • Digital and analog outputs as well as PROFINET connectivity for process control
Reflected light measurement systems for spray jet monitoring (Ex area)
  • Designed for extremely low spray quantities
  • High sensitivity hardware integrator for reliable detection of minimal spray pulses
  • Ex approved fiber optic frontend with air blast attachment to prevent droplet buildup
  • Ideal for restricted installation space or one sided access to the spray jet
Transmitted light measurement systems for spray jet monitoring (non-Ex area)
  • Wide range of laser light spots and curtains for different spray cone dimensions
  • Single , three , and multi channel variants for analyzing intensity, spray angle, symmetry, and profile
  • Line detectors for complete spray cone profile acquisition
  • PC software with SCOPE functionality for detailed signal evaluation
 
Additional measurement systems:

Transmitted light measurement systems for droplet detection (non-Ex area)
  • Inline monitoring of individual droplets for piezo nozzles or electromagnetic dosing systems
  • Droplet counting as well as measurement of droplet size and sequence
  • Ideal for pharmaceutical, electronics, and precision dosing applications
Inline spray jet control
  • Transmitted light method (single and multi channel systems), for Ex areas
  • Reflected light method (single channel systems), for Ex areas
  • Transmitted light method (single and multi channel systems), for non-Ex area
