For most applications, we recommend using an industrial threadlocking adhesive to secure a core connecting rod to an LVDT core. The adhesive should provide good shear strength, minimal creep, and long-term stability over the expected operating temperature range.
Key factors to consider when selecting an adhesive include:
operating temperature range
exposure to vibration or shock
environmental conditions (moisture, chemicals, oils, etc.)
cure time and handling requirements
In many cases, an off-the-shelf threadlocking adhesive is a suitable solution. However, adhesive selection can be application-specific, and using an improper product can impact performance or service life.
Examples of commonly used adhesives include:
Loctite 242
Loctite 609 (operating temperature range: −55 °C to 150 °C / −65 °F to 300 °F)
For higher-temperature applications, it is generally preferable to braze the core connecting rod to the LVDT core rather than use an adhesive.
