Campbell Scientific 110PV Surface Temperature Probe - Manual (Page 7)

110PV Surface Temperature Probe
1. General
The 110PV-L temperature probe uses a thermistor to measure temperature.
The probe is designed for measuring the back of photovoltaic (PV) module
temperature but also can be used to measure other surface temperatures. The
110PV-L is compatible with all Campbell Scientific dataloggers.
The 110PV-L consists of a thermistor encased in an aluminum disk (see Figure
1-1). The aluminum disk protects the thermistor and promotes heat transfer
from surfaces.
The probe measures temperature from –40° to +135°C. 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 or
high temperature epoxy is recommend to secure the probe to the measurement
surface. Kapton tape (P/N 27015) is available from Campbell Scientific.

The –L portion of the probes model number indicates the probe has a user
defined cable length which will be specified when the probe is ordered.
The probe’s cable can terminate in:
• Pigtails that connect directly to a Campbell Scientific datalogger (option
–PT).
• Connector that attaches to a prewired enclosure (option –PW). Refer to
www.campbellsci.com/prewired-enclosures for more information.
• Connector that attaches to a CWS900 Wireless Sensor Interface (option
–CWS). The CWS900 allows the 110PV to be used in a wireless sensor
network. Refer to
www.campbellsci.com/cws900 for more information.
For readability purposes, the probe will be referred to as the 110PV throughout
this document.
