LZW-M sensors with the analog output versions 5VT and 10VT are equipped with a teachable, internal electronics, called VT-Electronics. The signals provided by the sensor’s potentiometer are digitized by the VT-Electronics. This digital information is first processed by the electronics, then transformed back and given out as an analog output signal 0 to 10 V or 0.4 to 4.5 V. The digitization offers two possibilities of adjustment, by which the sensor can be configured individually using the Squeezer: 1) Teaching of the measurement range. After a successful teaching process the Squeezer can...
