Motor, generator and bearing temperature points are not interchangeable. A bearing point may need a compact form that fits the housing; a winding or equipment point may have a different access and lead route. Begin with the equipment drawing and identify the exact location, available space, mounting method, expected movement or vibration, lead exit, replacement access and monitoring input. Ask whether the instrument expects the selected RTD element and how the channel is used by the protection system. Also record the number of points and whether each point has the same physical arrangement.
The catalogue includes a Ring Type RTD, a Ring Type RTD with L Bending and a Ring Type RTD with SS Conduit. The Ring Type RTD record lists PT100 as an element option, SS304 and SS316 sheath options, and sheath diameters from 3 mm to 8 mm. The Ring Type RTD with L Bending record lists PT100, SS304 and SS316, with sheath diameters from 3 mm to 8 mm. These forms should be compared against the actual mechanical fit rather than selected from the name alone. Confirm the required element and dimensions from the applicable record.
Cable routing is part of the measurement decision. Record the lead length and route, nearby moving parts, available bend space and the point where the sensor connects to the monitoring system. An L-bend form may address a particular access direction, while an SS Conduit form may be relevant where that catalogue construction matches the installation. The selected record should be checked for its own element, sheath, dimensions and cable details. Consider how the cable will be protected while preserving the intended sensor position.
For a practical enquiry, provide the motor, generator or bearing location, drawing dimensions, mounting arrangement, lead route, RTD element requirement and instrument interface. Include whether the point is used for monitoring or protection and how the assembly will be replaced. These details let the relevant ring, L-bend or conduit RTD records be reviewed without assuming a fit or an operating limit. A marked drawing or mounting photograph can clarify the available space and lead direction. Include the existing sensor termination and the number of replacement assemblies required.
