A sensor includes a clevis insert for reception within a first bore of a clevis. The clevis insert is configured to accommodate a latch pin. A strain sensing element is operatively associated with the clevis insert for detecting mechanical strain imparted to the clevis insert when a force acts on the clevis insert through the pin. The invention also provides a method of retrofitting a cowl latch assembly.

A platinum resistance thermometer has an outer housing with a bore that receives a temperature sensor assembly including a mandrel having a sensing section with a platinum wire wound thereon and supported in the bore with a non-cohesive powder material that will distribute stresses caused by differential thermal expansion between the housing and the temperature sensor assembly. A second portion of the mandrel is supported in the bore with a rigid epoxy to mechanically support the sensor assembly with the sensing section cantilevered from the rigid epoxy.
