1. What is the bending limit for the cable on the 110PV-L?

   There is no outside visual damage bending the cable over on itself 180°. But for long-term durability purposes, any bends should not be smaller than a 0.5 in. radius.
2. Why is NIST traceability beneficial for surface temperature sensors, such as the CS240, the 110PV, and the CS240DM?

   NIST traceability provides an assurance of accuracy. This is especially desirable in accordance with IEC 61724, which is a specification for monitoring solar energy generation that requires calibrated sensors.

3. Can the 110PV-L be submerged?

   是的. After adhering the sensor to a dry surface, the sensor can be submerged up to 50 ft in depth.

4. What would indicate there is an issue with a 110PV-L?

   Some of the more common readings that indicate a sensor is malfunctioning include NANs (not a number) or unrealistic values such as a panel temperature reading of 500 degrees Celsius. If NANs occur, it is possible that there may be either programming or wiring errors. Double-check the setup, and contact Campbell Scientific for assistance if the issue continues. Depending on the sensor behavior, the sensor may need to be returned to Campbell Scientific for repair.

5. Using Short Cut, is the 110PV-L configured as a half bridge, 4-wire? If so, how is the resistance calculated, and what needs to be done so that the correct temperature range will be produced?

   Currently,Short Cutonly offers a half-bridge measurement option, and the resistance is not calculated. Each cable resistance is measured at the factory and labeled with its unique reading. That resistance value is called for when adding a 110PV-L sensor to theShort Cutprogram.

6. Does the 110PV-L have a completion resistor?

   是的, which means it can be wired directly to a data logger.

7. How are temperature sensors such as the 107, 108, 109, 110PV-L, and BLACKGLOBE-L calibrated?

   When these sensors are purchased, the following calibration services are offered:TEMPCALandTEMPCAL2.

   • TEMPCAL provides a single-point calibration and a calibration certificate. The single-point calibration determines the offset at 25°C with an uncertainty of ±0.05°C.
   • TEMPCAL2 provides a two-point calibration and a calibration certificate. The two-point calibration determines offsets at 30°C and 65°C with an uncertainty of ±0.05°C.

   For both of these services, calibration can be made at different values if it is requested by the purchaser at the time of purchase. In addition, both of these calibration services can be requested after sensor purchase using a return material authorization (RMA) number. To request an RMA number, refer to theRepair and Calibrationpage.

8. What are the different cable length choices available for Campbell Scientific sensors?

   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.
9. Where are the available cable termination options listed for a particular sensor?

   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

   如果一个传感器提供一个外星人,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.

10. How can a data logger be programmed to use a 110PV-L?

    That depends on which data logger is being used and how the 110PV-L has been wired. For more details,see the110PV-L Instruction Manual.
