System for verifying temperature measurement

摘要

The present application is directed to a system for verifying calibration of a temperature sensor comprising an above-ambient temperature verifier and a below-ambient temperature verifier. The above-ambient temperature verifier includes a first housing and an ohmic material contained within the first housing. At least one pair of electrodes is provided to direct an applied current through the ohmic material to heat the material. A well is provided within the ohmic material for accepting a temperature sensor. The well has an inner surface with access to the surface provided through an opening in the first housing. A compression assembly cooperates with the ohmic material to create intimate contact between the inner surface and the temperature sensor when the temperatures sensor is placed within the well. An above-ambient reference temperature monitor is also provided to maintain a calibrated temperature within the ohmic material. The below-ambient temperature verifier includes a second housing and a below-ambient reference temperature monitor to maintain a calibrated temperature of a below-ambient temperature medium. The system further includes the ability to log all temperature test measurements to the specific identity of each temperature sensor tested by using a unique identity read from an RFID tag located on each temperature sensor to be verified.
