Digital output cable sensors for integrations

The digital output cable sensors work with RS-232C or RS-485 communications and 12 to 24V DC. The sensors can be easily integrated on various platforms and seamlessly output digital data with the commands.

Bio-fouling mitigation for long-term deployments

Generally, the data qualities of conductivity and optical sensors are degraded by bio-fouling for the deployment period. That is a challenging issue for the sensor integrations on long-term mooring platforms. The sensitive sensors to bio-fouling have models (ACTW-CAR, ACLW-CAR, ALW-RS and MFL05/10/50W-CAD) with an anti-fouling mechanical wiper to inhibit biological growths. They provide high accuracy data, even if they are integrated on mooring platforms in high biological activity fields.

The ACTW salinity sensor's stability in the coastal ocean and lake were evaluated by the Alliance for Coastal Technologies ( http://www.act-us.info/evaluations.php#Salinity , ACT code: ACT-VS-09-06).




Bio-fouling covers the ACTW instrument but the conductivity electrode is clean by the anti-fouling wiper.
