DOL 43 Capacitive Relay Sensor

DOL 43 capacitive sensor for general detection of feed, grain and solid materials

The capacitive sensor is typically used as an empty, full and level indicator in tanks, silos and containers. DOL 43's powerful built-in relay can directly control many functions. DOL 43 LEDs show when its switches are activated. The sensor has NO (normally open) and NC (normally closed) outputs. All settings can be easily changed at any time.

Improved usability

The sensor features several special functions that improve usability:

• Reset the sensor to factory settings
• Reading the configured time delay
• Disable the delay
• Switch LED indicators on/off

The DOL 43 capacitive sensor has a built-in high-power 5A relay with a changeover function. It is available in two voltage variants: 10–30 V AC/DC or 90–250 V AC

DOL 43 has an off-delay option with adjustable delay duration. When activation ceases, the delay starts. Once it expires, the relay switches back. The delay duration is easily adjusted with two buttons.

Highly reliable sensor

Electronic rather than mechanical switches provide exceptional reliability, particularly because the electronics are fully encapsulated in a special plastic. This gives maximum protection against moisture and other external influences in harsh environments.

The sensor is CE, UL and C-UL certified and highly resistant to interference from electrical communication, such as mobile phones, and transients, such as those from motors and contactors. This makes it highly reliable.

Multiple mounting options

DOL 43 is easily mounted in a plastic gland, also available as a flanged solution for easy external mounting. A threaded version provides further mounting options. It can be installed inside a feeder or through an opening in a feeder, hopper or silo using the supplied plastic gland.
