The CS410 is a shaft encoder that measures water level for Campbell Scientific data acquisition systems. It connects directly to our data loggers; a QD1 interface is not required. All of our data loggers are compatible.Read More
The CS410 consists of a pulley attached to a float and counter-weight that rotates as water level rises or falls. When the pulley rotates, the CS410 sends two pulse strings to the data logger. The data logger records the pulse strings, and calculates water level by adding or subtracting the clockwise or counter clockwise movement to a running total. The encoder's resolution is 100 counts per shaft revolution, so a 1-foot circumference pulley has a resolution of 0.01 feet.
A complete measurement system requires a float, pulley, float tape or beaded float line, end hooks, appropriate-sized counter weight, and data logger. See the Ordering Information on the web page for products that are available from Campbell Scientific.

Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
The CS410 is measured by two pulse count channels on the data logger; one channel counts "up" pulses, the other counts "down" pulses, and then water level is determined in the data logger. Although all of our data loggers are capable of measuring the CS410, the larger data loggers generally exceed application requirements because CS410 installations are typically remote and usually aren't measured with many other sensors.

Not every sensor has different cable termination options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:
If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.
All of the other cable termination options, if available, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.
Note: As newer products are added to our inventory, typically, we will list multiple cable termination options under a single sensor model rather than creating multiple model numbers. For example, the HC2S3-L has a –C cable termination option for connecting it to a CS110 instead of offering an HC2S3-LC model.
Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. If a sensor is listed as an –LX model (where “X” is some other character), that sensor’s cable has a user-specified length, but it terminates with a specific connector for a unique system:
If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. The cable length is listed at the end of the Description field in the product’s Ordering information. For example, the 034B-ET model has a description of “Met One Wind Set for ET Station, 67 inch Cable.” Products with a set cable length terminate, as a default, with pigtails.
If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.
Many Campbell Scientific sensors are available with different cable termination options. These options include the following:
Note: The availability of cable termination options varies by sensor. For example, sensors may have none, two, or several options to choose from. If a desired option is not listed for a specific sensor, contact Campbell Scientific for assistance.
