720460 – RTD – DUAL FOR CCT-NC

Description

720460 – RTD – DUAL FOR CCT-NC – Works with all Harshaw, Engelhard, Atotech USA, Atlas and Auto Technology Company fog and cyclic corrosion test chambers.    PURPOSE:  The purpose of the Over-temperature RTD is to read the current temperature in the exposure zone and  report that signal or value to the cabinet over-temperature controller.    FUNCTION:  The over-temperature RTD is  constantly sending a temperature signal to the chamber overtemperature  controller. In most cases, two (2) RTD sensors are  housed in the same probe with one signal going to the cabinet  controller, and the second signal going to the cabinet overtemperature  safety controller. In this case the Dual  Temperature RTD is installed. From the sheath, it cannot be  determined if an RTD probe is single or double. To make the  determination, look at the number of wires exiting the probe.  Two or three wires indicate a single RTD probe. Four or six  wires indicate a dual RTD probe. The cabinet RTD is wired to  channel 1 of the RTD card on the input/output rack.
