Level Sensors

NR 60

Level Sensor NR 60 is designed to monitor water, oils and fuel. It may also be used in automatic filling systems.

NR 80

Level Sensor NR 80 is designed to monitor a preset medium level in electrically non-conductive containers with a wall thickness up to approx. 5 mm. It is fitted outside the container.
Suitable for water and other electrically conductive liquids with a high relative dielectric constant .
Available as MIN or MAX sensor.

NR 100

Level Sensor NR 100 is designed to monitor liquids, granules, and powder. It is especially suitable for aggressive media and foodstuffs.

Available as MIN or MAX monitor.

NR 150

Level Sensor NR 150 is suitable for liquids with low relative dielectric constant
(e.g. oil).

With MIN/MAX selector switch.

NR 160

Capacitive Level Sensor NR 160 is designed to monitor liquids and powders with high relative dielectric constant.

With MIN/MAX selector switch.

NR 200

Capacitive Level Sensor NR 160 is designed to monitor oil and media with low relative dielectric constant.

With MIN/MAX selector switch.

NG 03

The NG 03 power supply is suitable for E-T-A Level Sensors NR 60, NR 80, NR 100, NR 150 and NR 160. It has a relay output with adjustable switching delay which is controlled by the signal output of the sensor. Status indication is by green LED. Power failure and wire break are indicated in the same way as incorrect medium level (closed circuit principle).

NR 200

E-T-A's new non-contact level sensor detects the presence or absence of liquids at a chosen level within plastic tubes, rubber hoses, and small glass or plastic pipes. The sensor is simply snapped onto the tube at the level you wish to monitor.
