Campbell CS220, CS220-L Information

COMPONENTS

CS220

Surface-Mount Type-E Thermocouple Sensor

Fast Response

Ideal for monitoring

solar panel temperature

Overview

The CS220 thermocouple measures the temperature of a surface
by direct contact. It typically monitors the temperature of a solar
panel, but can also monitor the temperature of other devices.

Benets and Features

Well-suited for solar energy applications
Thermocouple tolerance meets ASTM E230-ANSI MC 96.1

(reference junction at 0°C)

Type E Thermocouples

Type E thermocouples are comprised of a chromel wire and a
constantan wire joined at a measurement junction. A voltage
potential is generated when the measurement end of the ther­mocouple is at a dierent temperature than the “reference end”
of the thermocouple. The magnitude of the voltage potential is
related to the temperature dierence. Therefore, temperature can
be determined by measuring the dierences in potential created
at the junction of the two wires

Panel temperature is an important measurement in solar energy
applications since the output of a solar panel is aected by its
temperature. As the temperature of the solar panel increases, its
output decreases.

Easy to install
Compatible with most Campbell Scientic dataloggers

A reference temperature measurement (typically measured at the
datalogger wiring panel) is required. Options for measuring the
reference temperature include:

Thermistor built into the CR800, CR850, CR1000, CR3000, or
CR5000 wiring panel

PRT built into the wiring panel of the CR9050 or CR9051E input
module for the CR9000X Measurement and Control System

Installation

The CS220 usually adheres in the center of the back panel of a so­lar module. Once the mounting location is determined, clean the
back panel surface. Use extreme caution removing the masking
paper from the measurement end of the thermocouple; damage
can occur if masking paper is not removed carefully. Once mask­ing paper is removed, rmly press thermocouple to the panel.
Adhere the cable strain relief 2 to 3 in. from the end. Connect the
mini connector on the stainless-steel overbraided cable to the
mini connector on the thermocouple extension cable. Wire the
pigtails of the thermocouple extension cable to the datalogger,
as determined by the datalogger program/wiring table.

The CS220 is shipped with a stainless-steel overbraided cable and a
thermocouple extension cable. The pigtails of the extension cable
connect to the datalogger (see Wiring Table).
