KA7000

KA7000 sensor hot sun

A sensor for high temperature applications.

Download the specification sheet for this sensor: PDF

Description:

The KA7000 sensor operates safely at a higher temperature than standard capacitive sensors. This is required for applications when heat generating equipment is part of the process where the sensor is being used. The KA7000 sensor can be used in applications where the temperature on the active area of the sensor is up to 248°F (120°C).

The KA7000 sensor is made of durable materials that can withstand the harsh environments of plastic processing. This sensor has excellent resistance to abrasion, static electricity, and high vibration. For applications where extra resistance to static electricity is needed, a sensor with a PTFE housing or a Rechner High Performance sensor should be used.

Adjustment instructions

After installation, a 'full adjustment' of the sensor is done in this order:

  1. Locate the sensitivity adjustment potentiometer on the sensor. The adjustment potentiometer is recessed and located under a plastic flap that is there to keep dust out.
  2. Fully immerse the sensor into the bulk material.
  3. Reset the sensor's sensitivity by turning the potentiometer counter-clockwise 20 full turns, or until the sensor no longer sees the product (whichever comes first).
  4. Adjust the sensor to the product to be detected by turning the potentiometer clockwise until the sensor detects the product.
  5. Add 1/4 turn for safety by turning the potentiometer a further 90 degrees clockwise.
