Abstract
In an apparatus for measuring the downhole force applied to a cable suspending a well-logging apparatus in a borehole, an elongated sensitive element has a strain gauge integrally bonded upon it for measuring the downhole force. The apparatus is provided with elements for compensating for pressure and temperature changes in the borehole, wherein an envelope is sealingly disposed about the strain gauge and is formed to allow the sides of the envelope to deflect inwardly and outwardly from the strain gauge in response to changes in pressure and temperature in the borehole. The envelope is filled with oil.
