RECHNER SENSORS CAPACATIVE AND INDUCTIVE SENSORS

Since its founding in 1965, Rechner Sensors has held a leading position in the field of sensor technology and has since developed capacitive and inductive sensors for demanding industrial applications. This is especially true in the area of ​​capacitive sensors for level control or position control. Many consider the name Rechner as synonymous with a capacitive sensor.

Practical solutions

By combining extensive product development with advanced sensor technologies, Rechner solves practical industrial problems that had no previous practical solution.

Due to the rapid developments on the market and specific customer demands, the assortment is constantly growing. The assortment has more than 3000 models, with a wide range of different sizes and process connections.

Capacitive sensors can detect both metal and non-conductive materials such as glass, paper, oil, water etc. Capacitive sensors are insensitive to dust and dirt and offer maximum insensitivity to magnetic interference. Capacitive sensors are ideal to use for level measurement of liquids and monitoring of solid materials. Rechner Sensors has special level sensors, the range for level measurement. Read more about capacitive sensors

In addition to the materials to be detected, the following factors are important for the choice of a sensor type:

  • Switching distance
  • Installation type: concise / non-concise
  • Construction: cylindrical / rectangular
  • Connection: connector / cable
  • Output type: PNP / NPN

INDUCTIVE SENSORS | PROXIMITY SENSOR

An inductive sensor or inductive proximity sensor works according to the principle of change of impedance / inductance. When the proximity sensor comes close to a metal object, the inductance / impedance changes in the coil. This change in inductance or impedance depends on the distance between the metal object and the sensor. The inductive sensor or inductive proximity sensor is ideal for detecting ferrous metals (alloys where iron is the main ingredient) at a short detection distance and is not affected by non-conductive materials such as wood and plastic. Read more about inductive sensors

Proximity sensor

Proximity sensors are not optical sensors, but react to metal objects using magnetic fields. Proximity sensors are implemented in concise and non-concise sensors. Proximity switches are insensitive to dust, sunlight, dirt and reflections. An inductive sensor is often used in harsh conditions with short switching distances and metal objects.

Rechner sensors to avoid interference and downtime

The capacitive Smart Paddle from Rechner is there for the level control of bulk goods and is designed for liquids with an electric constant of 2 to 80. It can not be simpler: the user installs the sensor, connects it electrically and the level sensor is ready for the measurement. Read more about capacitive sensor for level control

Pharmaceutical and food industry

The Smart Paddle is made of food contact safe material which makes sensor ideal for applications in the pharmaceutical and food industry. The Smart Paddle is safe to clean (CIP / SIP cleaning) at high temperatures (zero flow, 121 ° C) and is suitable for high pressure, 10 bar 145 PSI.

Easy and Reliable Analogue Level Control

The Rechner Sensors capacitive level probe for analogue level measurement from RECHNER Sensors also has 2 additional binary switching points. The user can set the analogue measuring range anywhere within the measuring area. The two switching points can also be positioned anywhere over the whole measuring area, either within or outside of the set analogue measuring range. Read more about analogue capacative sensor for level measurement

26-series | Rechner Sensors

The alternative to tuning forks, rotary and float switches

The 26-series capacitive sensors are High Performance (HP) sensors with unique characteristics in terms of size and shape of the sensor. The 26-series sensors perform better than any sensor when it comes to ignoring material accumulation. Originally developed to optimize the detection of viscous and caking products, the 26 series of capacitive proximity switches has developed into a problem solver for many applications.

Sensor with analogue output for level control of products in liquid form

The LevelMaster-sensors by RECHNER Sensors are developed for the level monitoring of products in liquid and sticky form that are adhesive and/or conductive.
Depending on the selected type, the analogue LevelMaster can be used to carry out an analogue fill level measurement across a defined range. At the same time, it is also possible to detect any signs of pollution so that a cleaning process can be triggered. Another application option is a display of the change in the dielectric constant (DC) of the product to be monitored for quality control. For quality control purposes, the empirically determined starting values can be controlled and analysed using for example a PLC.
