The 110PV is a thermistor that measures the temperature of a surface by direct contact. It typically monitors the temperature of a photovoltaic module, but can also monitor the temperature of other devices. This thermistor easily interfaces with our dataloggers, and is ideal for solar energy applications.Read More
The 110PV consists of a thermistor encased in an aluminium disk. The disk protects the thermistor and promotes heat transfer from surfaces. An adhesive tab on the probe’s aluminium 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.

Please note: The following shows notable compatibility information. It is not a comprehensive list of all compatible 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.
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.
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.
That depends on which data logger is being used and how the 110PV-L has been wired. For more details, see the 110PV-L Instruction Manual.
Yes, which means it can be wired directly to a data logger.
In either a 3-wire or 4-wire half-bridge configuration. For details, refer to the 110PV-L Instruction Manual.
The sensor behaves exceptionally well (temperature uncertainty <0.2°C) between -40 and +80 degrees Celsius.
Yes. After adhering the sensor to a dry surface, the sensor can be submerged up to 50 ft in depth.
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.
