Overview

The CS410 is a shaft encoder that measures water level for Campbell Scientific data acquisition systems. It connects directly to our dataloggers; a QD1 interface is not required. All of our dataloggers are compatible.

Benefits and Features

  • Measures water level in stilling wells
  • Rugged enough for harsh environments
  • Low power consumption
  • Connects directly with our dataloggers (no interface required)
  • Compatible with all Campbell Scientific dataloggers (including the CR200(X) series)

The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description

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 datalogger. The datalogger 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 datalogger. See the Ordering Information on the web page for products that are available from Campbell Scientific.

Datalogger Considerations

The CS410 is measured by two pulse count channels on the datalogger; one channel counts "up" pulses, the other counts "down" pulses, and then water level is determined in the datalogger. Although all of our dataloggers are capable of measuring the CS410, the larger dataloggers generally exceed application requirements because CS410 installations are typically remote and usually aren't measured with many other sensors.

  1. 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:

    • Model number
    • Cable Termination Options list

    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. 

  2. 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:

    • An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
    • An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.

    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.

    • –ET models terminate with the connector for an ET107 weather station.
    • –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
    • –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
    • –PW models terminate with the connector for a PWENC or pre-wired system.
  3. Many Campbell Scientific sensors are available with different cable termination options. These options include the following:

    • The –PT (–PT w/Tinned Wires) option is the default option and does not display on the product line as the other options do. The cable terminates in pigtails that connect directly to a datalogger.
    • In the –C (–C w/ET/CS110 Connector) option, the cable terminates in a connector that attaches to a CS110 Electric Field Meter or an ET-series weather station.
    • In the –CWS (–CWS w/CWS900 Connector) option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.
    • In the –PW (–PW w/Pre-Wire Connector) option, the cable terminates in a connector that attaches to a prewired enclosure.
    • In the –RQ (–RQ w/RAWS Connector) option, the cable terminates in a connector that attaches to a RAWS-P Permanent Remote Automated Weather Station.

    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.
