DRY BLOCK TEMPERATURE CALIBRATOR

Abstract

The present invention patent application, belonging to the field of Instrumentation and industrial metrology, comprises a dry block temperature calibrator (6), which has a block (7), and a closed system comprising: two heat sinks (1) using water to cool the Peltier element (2), and consequently the cooling of the metal block (3) used to test/calibrate temperature sensors, a pump (24) that directs the water flow to the high-efficiency radiator (5), and then the water flow is recirculated to the heat sinks (1) concluding the closed system.

Claims

1. A DRY BLOCK TEMPERATURE CALIBRATOR, comprising a heat block (3) with a Peltier element (2) on each side of the block (3), and a heat sink (1) coupled to each Peltier element (2) to perform heat exchange, wherein the cooling of the Peltier element (2) is performed by water, and consequently cooling the metal block (3) used to test/calibrate temperature sensors, a pump (24) that directs the water flow to the high-efficiency radiator (5), and then the water flow is recirculated to the heat sinks (1) concluding the closed system.
