Multiple NexSens data logger models and CB-MCL wet-mate lids include male and female Micro-Circular Bulkhead (MCBH) connectors compatible with Micro-Circular In-line (MCIL) sensor connectors. These connectors are designed for use in wet conditions (not while submerged) as they force out water as connectors are mated. Like other connector types, MCBH and MCIL connectors still require […]

In-Situ AquaTroll X-Series Integration Guide
Real-Time Water Quality Measurements The In-Situ Series of Multi-Parameter Water Quality Sondes (AquaTroll 200/400/500/600) are compatible with NexSens X-Series data loggers using the Modbus-RTU communication protocol and RS-485 sensor interface. A pre-defined script on X-Series data loggers is able to detect, log and transmit all parameters available on all models of In-Situ sondes. Parameter data […]
VegaPuls C 23 Radar Water Level Sensor X-Series Integration Guide
Real-Time Water Level Measurements The VegaPuls C 23 Radar Water Level Sensor provides non-contact, continuous level measurements. The sensor is compatible with NexSens X-Series data loggers using the SDI-12 communication protocol and sensor interface. A pre-defined script on X-Series data loggers is able to detect, log, and transmit all measurement parameters. Parameter data is transmitted, […]
What are the maximum cable lengths supported by X-Series data loggers?
X-Series data loggers support the RS-232, RS-485, and SDI-12 sensor interfaces using NMEA0183, Modbus, and SDI-12 communication protocols. Below is a general guideline for the maximum reliable cable length for each interface. SDI-12 RS-232 RS-485 200 ft. (~60 m)* ~164 ft. (50 m)** 4000 ft. (~1,200 m) *The SDI-12 bus is capable of having 10 […]
YSI ODO Calibration Utility
Utilize the YSI ODO calibration utility to enter calibration coefficients when installing new DO sensor caps. Calibration coefficients are located on the “YSI ODO Sensor Cap Instruction Sheet” included with the new sensor cap. Once entering the coefficients, the user will need to perform a 1-point DO calibration within the utility. CONNECT will utilize the […]
What is required for a Main SD card replacement?
If the main SD card fails in an X2 data logger, a NexSens technician will provide two folders that must be installed on a replacement card. Replacement SD cards can be sourced independently or purchased directly through NexSens’ U.S. distributor, Fondriest Environmental. The X2 requires a 256 MB industrial-grade SLC SD card. Consumer-grade SD cards […]
Common Tools Required for Deployment and Maintenance
During a buoy deployment or maintenance, the tools required will vary based on the buoy accessories purchased with the order, including beacons, sensors, and sensor mounts. However, a host of tools will be necessary across nearly all data buoy platforms. Any technician responsible for a buoy deployment or maintenance should bring the following tools to […]
General Data Buoy Maintenance
The following practices should be carried out for general CB-Series data buoy maintenance during normal operation. As a general practice, measurement data should regularly be inspected, and Quick Alerts or Alarms should be configured in WQData LIVE to detect any anomalies which may indicate that maintenance is required. Immediate Steps for Buoy Maintenance Monitor the […]
Replace G2-RAIN Siphoning Bucket
The G2-RAIN has two versions of the siphoning bucket depending on the time of purchase. For all models purchased before 2021, the G2-RAIN will have the siphoning bucket manufactured by the Rickly Hydrological Company. Newer G2-RAIN models have the siphoning bucket manufactured by Hyquest Solutions. In the instance of a bucket replacement, follow the steps […]
