Capacitive sensors react to metals and non-metals that exceed a specific capacitance on approaching the active surface. The sensing distance with respect to a specific material is greater the higher the dielectric constant. These sensors are used to detect objects, for counting functions and for all types of level monitoring applications in liquid materials (i.e. water, oil, acids, glue) and bulk materials (i.e. powder, granulate, pellets).
The basic line of capacitive sensors is the High Performance line. These are designed for highly demanding applications. They have excellent characteristics:
Up to 3x longer working distance than standards
Working distance is optimized for most materials
A smaller free area in the active zone is required
Temperature stability up to 100°C
Excellent EMC characteristics
2-color LED signaling
The series Normline are sensors for standard applications, made in accordance with all international standards and ensure quality and reliability of operation.
For special applications, there are additional series of capacitive sensors:
Series 95 - with relay outputs, intendend for use in the agri-food industry and feed production
- High Performance technology - intelligent technology with microcontrollers - adjustable delay time options - very low consumption, only 2mA - direct control up to 1A
Series 26 - in principle designed to solve problems with highly adhesive materials. They have excellent characteristics for the purpose of level detection.
