Not every sensor comes with a calibration sheet. If a calibration sheet is included, it is listed in the “Ships With” section of the sensor’s product web page or it is specified when ordered.
Sometimes, an old cable can be replaced with a new, shorter cable.
Sometimes, an existing cable can be shortened by cutting the ends off. However, there are a few issues that could be encountered when doing this:
Because of the potential issues, do not cut the ends off any sensor cable without first contacting Campbell Scientific to discuss the sensor in detail.
Whenever possible, purchase a sensor with the desired cable length. Some sensors have a user-specified cable length, whereas other sensors have a set cable length.
Sometimes, an old cable can be replaced with a new, longer cable.
Generally, additional cable cannot be spliced onto the existing cable because:
Splicing cable together increases the likelihood that water may enter the cable and cause shorting, corrosion, and some other potential issues, which in turn can cause measurement issues.
Because of the potential issues, do not splice any sensor cable without first contacting Campbell Scientific to discuss the sensor in detail.
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.
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.
For thermopile pyranometers, a thermopile is used within the instrument as the sensor, and the thermal gradients are measured across hot and cold areas (black and white). The radiation intensity is proportional to the temperature differences between the two sensing areas. Accuracy depends upon the sensitivity of the material used in the sensors, the response time, and the distortion characteristics of the material constituting the dome (if present) covering the sensors.
For silicon photocell pyranometers, electric current is generated by a photo-sensitive diode in proportion to solar intensity. Ordinarily, silicon photocell pyranometers are not fully sensitive to the full spectrum of visible light, and they cannot “see” a certain portion of the electromagnetic spectrum such as under cloudy conditions or vegetative canopies. Silicon photocell pyranometers will introduce errors under these conditions. In full sunlight conditions, however, they are calibrated to properly output solar radiation measurements.
Many times, but not always, a sensor’s cable can be replaced with a new cable. This is helpful if the original cable was damaged or if its length needs to be changed.
If the cable is attached to the sensor using a connector, Campbell Scientific will sell a replacement cable. For example, a 05106CBL-L is a replacement cable for a 05106-L. Replacement cables are listed in the “Replacement Parts” section of the Ordering information area of the product page.
If the cable is attached to a sensor through a user-accessible terminal block, a raw cable can be purchased to replace it. For example, to replace the cable on a 05103-L Wind Monitor, order the desired length of pn 9721, 24 AWG 3 Twisted Pair Shielded Santoprene Cable. As another example, the raw cable for a TE525-L Rain Gage is pn 9661, 22 AWG 1 Twisted Pair Shielded Santoprene Cable.
If the cable is an integral part of the sensor, the cable cannot be user replaced, and the sensor must be returned to Campbell Scientific. Some examples of sensors that fall into this category include the 107-L, 109SS-L, 229-L, CS547A-L, and CS650-L. For the process of returning equipment to Campbell Scientific, refer to the Repair and Calibration page.
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.
