CAPACITIVE SENSORS

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.

Detection range

Capacitive sensors have a detection range of 1 to 25 mm. Capacitive sensors are ideal for harsh conditions with short switching distances and for detection of non-metallic objects.

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

PROGRAMMABLE ANALOG SENSOR FOR LEVEL MEASUREMENT

The capacitive analog sensors perform level measurement over a certain range. The analog level sensor can detect contamination. The analog level switch also shows changes in the dielectric constant (DC).

Switching in the PLC

When changing the product or liquid to be measured, the programmable analog level sensor can easily be switched in the PLC. The sensors are equipped with EasyTeach by Wire (ETW). Read more about programmable analog level sensors.

MULTIFUNCTIONAL CAPACITIVE APPROACH SENSOR CIP / SIP UP to 121ºC

The active surface of the capacitive proximity sensor is designed in such a way that caking materials disappear better and faster from the surface. The level sensor is often used in the chemical and pharmaceutical industry and food industry.

Application for different materials

One capacitive proximity sensor can be used for different materials. The level sensor is equipped with classic or semi-circular electrodes. The active zone enables CIP / SIP up to 121 ºC. Depending on the model, the level sensor can withstand +100 ºC. Read more about the capacitive proximity sensor from Rechner Sensors

Prevent downtime and faults | Smart Paddle

The Smart Paddle from Rechner Sensors is a capacitive sensor. The level sensor is for the level measurement of bulk goods and is designed for liquids with a dielectric constant of 2 to 80. Connect the level switch electrically and the proximity switch is ready for measurement.

Maintenance free

The capacitive sensor has no moving parts and is maintenance-free. The level switch is ideal for applications where rotating sensors, vibrating forks and mechanical switches are used. Materials with a dielectric constant outside the range of the level switch there is a variant with EasyTeach-by-wire principle.
