RTD Sensors for Motors & Bearings

Temperature measurement on rotating equipment begins by naming the part and point being measured. A bearing temperature point is not the same as a motor or generator winding point; each has different access, mounting and lead-routing constraints.

Use the equipment drawing and monitoring-system requirements to describe the location. Confirm the selected sensor construction and performance against its own published product record and the actual installation.

For a bearing point, specify which bearing and the precise location from which temperature is to be measured; do not substitute a winding or general equipment reading. For a motor or generator winding point, identify the winding and its intended sensing location separately.

Do not assume an operating temperature, sensor rating, cause of a temperature change or preferred sensor type from the equipment category alone. Provide the expected conditions and use the equipment and sensor records to confirm a suitable measurement arrangement.

For bearing monitoring, mark the target bearing and measured point on a drawing and document available space, mounting arrangement, lead exit, replacement access and expected vibration context. These are inputs for engineering review, not an assumed construction or vibration rating.

For a motor or generator winding measurement, identify the winding location and installation constraints independently. Do not assume a sensor type, insulation or electrical rating unless it is stated in that product’s own specification.

There is no bearing-specific product recommendation on this page: the reviewed ring-type catalogue records do not explicitly identify bearing use. For any proposed product, compare the exact point, element, dimensions, mounting and connection requirements with the product’s own specification; request engineering confirmation where its stated use does not resolve the question.

Follow the equipment drawing and approved site procedure for mounting. Record the bearing or winding point, sensor position, lead route, connection and replacement details, and check that the installed arrangement matches the defined measurement point.

• A clearly identified bearing point keeps the measurement record tied to the intended location.
• Separate point descriptions distinguish bearing and winding measurements.
• Documented routing and installation details support consistent replacement.
• Product selection can be checked against the actual instrument input and installation.
