ENG 1. INTRODUCTION 1.1 General description The Carel passive temperature probes are devices that, when connected to the controller, provide a resistance value, which is then converted to a temperature by the electronic controller. These are used in HVAC/R applications, and represent a complete range capable of satisfying a variety of needs in di erent installations. The probes are made using materials that guarantee constant quality. The range includes various models that di er based on the performance of the system and the elds of application. The probes have di erent types of sensor (NTC, PTC, Pt1000), caps, index of protection, cable length, operating ranges and mechanical dimensions. In addition, models are available for use in hydronic systems, applied directly onto the tubing, which simplify installation and o er a faster response in the reading, improving the wiring of the HVAC/R unit and improving performance. The probes are used together with Carel electronic controllers (parametric and programmable). 2.
