Rod and Suspension Electrodes

• cost-efficient to purchase
• Easy to install
• Ex-enabled
• robust

The electrodes are used for conductive detection of limit levels. The areas of use cover all sectors where liquid and conductive media are to be detected or controlled.

Limit value measurements (overflow, dry run, max. alarm) as well as min./max. control and pump control (hysteresis) can be implemented.

Construction

The electrode consists of an enclosure with up to 5 rod electrodes/suspension electrodes. The unit can be fastened using a G 1 1/2“ or G 2“ connection thread together with a wall mounting angle.

Function

A low alternating current flows once the electrode is submersed into a conductive liquid. This alternating current is evaluated by the switching amplifier (electrode relay).

Exceeding an adjustable trigger threshold will energise the according relay.

Typical applications for suspension and rod electrodes

• Shafts/containers with pump control
• Overflow messages and limit level monitoring
• Limit level messages for release/counters on stormwater treatment plants
• Monitoring according to WHG
• Overfill protection
• Dry run protection
• and many more
