Installed assembly
For BT34, start with the real installation rather than the appearance of a similar component. Record the mating device, drawing revision, power supply, connection, mounting position and environmental conditions. The complete BT34 code is the ordering key. Accessories and certificates may be separate line items, so request confirmation of the entire installed assembly.
Purpose in the process
The operational role of BT34 is to present two fixed operating surfaces to an F25 position-feedback sensor. Document the expected input condition and the required output or mechanical response. A change in host electronics, wiring, hazardous-area classification or process medium can alter whether BT34 remains suitable. Similar-looking designations listed below are inventory references only, not declared substitutes.
Mounting and connection
Before installation of BT34, Confirm shaft diameter, operating-surface orientation and fastening torque. Inspect the exact terminals, mechanical engagement and clearance against the manufacturer's drawing. If the installation is Ex-rated or safety-related, validate the complete certified circuit and site procedure. Do not copy limits from a visually similar suffix onto BT34.
Functional acceptance
To accept BT34, observe a known normal state and a known changed state at the connected host. Record the measured values, output indication and controller response. Where adjustment or configuration exists, preserve its settings before removing the former unit. Check the working-range edge and repeat the test after final mechanical fixing of BT34.
Order description
