Product catalog summary

Company Development
CAPTRON Electronic GmbH, established in 1983 in Munich, specializes in innovative sensor technology, particularly capacitive sensors for automation and traffic engineering. The company expanded its offerings in 1992 to include optical sensors and introduced capacitive SENSORswitches in 1994, becoming a leader in capacitive level measurement.

Capacitive Measurement Principle and Selection Criteria
The capacitive measurement principle relies on changes in the capacity of a capacitor, with the probe rod and tank wall as electrodes and the medium as the dielectric. Selection criteria include tank material, media type, temperature, pressure, protection class, and device connection, ensuring adaptability and reliability across industries.

CAPselect System
The CAPselect system offers customizable level measurement probes, including compact probes and those with external amplifiers for high-temperature applications. Users can select components like electronics, process connections, and probe rods for tailored solutions.

WHG§19 Approval
CAPselect probes comply with the German Water Management Act (WHG) §19, which mandates safety devices for tanks with water-hazardous liquids to prevent overfilling and ensure process safety.

Industry Applications
CAPTRON products cater to various industries, including chemical, water and wastewater, food and pharmaceutical, mechanical engineering, and two-component systems. The customizable probe systems meet specific industry demands with corrosion-resistant materials and adherence to safety standards.

Technical Specifications
The document provides detailed technical data, ordering codes, and examples of customer-specific probes, aiding users in selecting appropriate components for their applications.

Overview
The document outlines technical specifications and features of CAPTRON's miniature probe with switching output, compliant with §19 of the German Water Management Act (WHG), requiring safety equipment for tanks with water-pollutant liquids.

Specifications
The CAPTRON probe features eight amplifier levels for high accuracy, an intuitive operating unit with SENSOR switches for quick calibration, and a bright LED bar indicator for distant level reading. It offers various analogue and switching outputs, housed in anodised aluminium or stainless steel (V4A) with a robust M12 connector.

Probe Amplifier
The probe amplifier connects to the rod probe via a process connection and can be adjusted up to 350° post-installation. It is available in a hygienic version (V4A) and withstands temperatures up to 180°C with an external amplifier.

Process Connections
Compact and easy to integrate, process connections are available in stainless steel (V4A), Teflon, or PEEK, with options for an M8 connector for a PT100 temperature sensor and high-power LED illumination.

Probe Rods
Made from virgin PTFE, probe rods are available in diameters of 21 mm and 14 mm, with lengths up to 3000 mm, suitable for different tank types and media.

Options
Additional options include a PT100 temperature sensor for medium temperature measurement and a LightCAP version with high-power LEDs for tank illumination.

Ordering Information
The document includes an overview and ordering code for compact probes, detailing available materials, process connections, and configurations.

Specifications for Robust Analogue Oil Probes
Designed for difficult-to-access areas, these probes are made of stainless steel V4A, with a standard rod length of 60 mm and options up to 300 mm. They feature an analogue output of 4...20 mA and a jacket tube diameter of 21 mm.

Procedures and Functionality
The probe amplifier evaluates media flow towards the probe rod, activating a switching output when a reference level is exceeded, with options for PNP switching output or relay contacts.

Materials and Options
Rod materials include PTFE and PEEK, with thread materials available in PTFE, PEEK, V4A, brass, and V2A. The document outlines options such as temperature range up to 180°C and compression-proof up to 10 bar.

Technical Data
The amplifier operates at 10-30 V DC, with a protection rating of IP65. The switching output can handle a load current of 300 mA for transistors and 3 A AC for relays.

Accessories
Available accessories include protective caps, fixing accessories, adapters, electronic converters, and connecting cables.

Customer-Specific Probes
Examples of custom-designed probes developed in collaboration with customers are provided.

Dielectric Constant Values and Compatibility
A list of dielectric constant values and compatibility with PTFE and PEEK rods is provided, offering guidance for selecting materials for chemically aggressive substances.
