WARRANTY
The manufacturer warrants this product to be free from defects in material and workmanship under normal use
and service for the period of one year from date of purchase, except as hereinafter provided. This warranty
extends only to the original purchaser (a purchase from Raytek or a licensed distributor of Raytek is an original
purchase). This warranty shall not apply to fuses, batteries, or any product which has been subject to misuse,
neglect, accident, or abnormal conditions of operation.
In the event of failure of a product covered by this warranty, the manufacturer will repair the instrument when it
is returned by the purchaser, freight prepaid, to an authorized Service Facility within the applicable warranty
period, provided manufacturer’s examination discloses to its satisfaction that the product was defective. The
manufacturer may, at its option, replace the product in lieu of repair. With regard to any covered product
returned within the applicable warranty period, repairs or replacement will be made without charge and with
return freight paid by the manufacturer, unless the failure was caused by misuse, neglect, accident, or abnormal
conditions of operation or storage, in which case repairs will be billed at a reasonable cost. In such a case, an
estimate will be submitted before work is started, if requested.
THE FOREGOING WARRANTY IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED,
INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTY OF MERCHANTABILITY, FITNESS, OR

The ThermoViewTM Pi20 is a rugged thermal imaging camera designed for industrial process control
applications. The camera is designed with an IP54 rating to withstand demanding industrial
environments.
The ThermoView Pi20 provides easy networking over long distances using the standard Ethernet
interface. This interface allows for the PC operating the DTPi software to be located far away. The
Ethernet interface transmits up to 30 frames per second of imaging data and also allows for camera
control. For long Ethernet cable runs beyond 90 m (295 ft), additional fiber optic Ethernet accessories
are available.
The ThermoView Pi20 process imager is a noncontact and highly sensitive infrared thermal camera.
The infrared radiation emitted from measured objects is detected and converted to an electrical signal
by a two-dimensional uncooled focal plane array detector. After this, the amplified analog
temperature signal is converted to a digital signal, which is displayed as a thermal image in color or
black-and-white on a PC running TSA or DataTemp®(DTPi) software.
