You can use the 110PV thermistor to measure the temperature of a surface by direct contact. It typically monitors the temperature of a photovoltaic module, but you can also use it to monitor the temperature of other devices. This thermistor easily interfaces with our data loggers, and it is ideal for solar energy applications.Read More
The 110PV consists of a thermistor encased in an aluminum disk. The disk protects the thermistor and promotes heat transfer from surfaces. An adhesive tab on the probe’s aluminum disk fastens the 110PV to the measurement surface. If the temperature may exceed 70°C, Kapton tape is also required to secure the probe; Kapton tape is offered as a Common Accessory (see Ordering Info). Note: Campbell Scientific does not recommend using epoxy to secure the 110PV to a PV module.
The 110PV can provide the photovoltaic (PV) module temperature for solar-energy applications. This measurement is useful because the output of a PV module is affected by its temperature. As the temperature of the PV module increases, its output decreases.

Note: The following shows notable compatibility information. It is not a comprehensive list of all compatible or incompatible products.
For temperatures up to 70°C, an adhesive tab on the probe’s aluminum disk fastens the 110PV to the measurement surface. If the temperature may exceed 70°C, Kapton tape is recommended to secure the probe to the measurement surface. Kapton tape is available from Campbell Scientific (see Ordering Information).
The 110PV can be submerged to 50 ft, but the probe’s adhesive tab is not intended for submersion. Therefore the 110PV must be mounted to the measurement surface via a user-supplied method that is compatible with submersion.
The CR200(X)-series dataloggers use the ExDelSe instruction to measure the 110PV. The CR800, CR850, CR1000, CR3000, CR5000, and CR9000(X) can use either the BrHalf4W instruction or BrHalf instruction to measure the 110PV. For these data loggers, the BrHalf4W instruction is typically preferred because it reduces cable errors. The BrHalf instruction requires fewer input channels.
In Edlog, Instruction 5 is typically used to measure the 110PV. The ratio metric output is then converted to resistance and finally to temperature.

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.
Yes. After adhering the sensor to a dry surface, the sensor can be submerged up to 50 ft in depth.
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.
Currently, Short Cut only 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 the Short Cut program.
Yes, which means it can be wired directly to a data logger.
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 returned material authorization (RMA) number. To request an RMA number, refer to the Repair and Calibration page.
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.
The sensor behaves exceptionally well (temperature uncertainty <0.2°C) between -40 and +80 degrees Celsius.
