Wire Style Bearing & Autoclave Sensors
Wire Style Bearing and Autoclave Thermocouples & RTDs are used in bearing applications where the element is going to be installed in a recess in the bearing babbitt. These sensors enable temperature monitoring of the bearing to prevent overheat conditions that can cause damage if left unattended. The feedthrough sleeve enables mess free installation and operation so that, once installed, lubricant stays in the bearing and not in the terminal box!
These sensors are also excellent solutions for autoclave applications where a sensor needs to penetrate the autoclave wall without leaking or leeching moisture.

A: Thermocouple and thermocouple materials are normally supplied to meet the tolerances specified in the table of temperatures above 0°C. The same materials, however, may not fall within the tolerances given for temperatures below 0°C in the normal section in the table. If materials are required to meet the tolerances stated for temperatures below 0°C the purchase order must specifically state that requirement. Selection of materials will usually be required.
B: Special tolerances for temperatures below 0°C are difficult to justify due to limited available information.
*: Standard and special limits of error in °F are 1.8 times larger thant the °C tolerance at the equivalent °C temperature.
