Description：
|
It uses a hydraulic activated device to close and open the caliper arm. The 4 orthogonal independent borehole radii can be measured. After digitalization, the signals communicate with telemetry / GR tool by Ethernet through 10M communication interface board. There are 15 through wires, and 31-pin connectors at up and down heads as per 580 standards

FUNCTIONCOMPOSITIONTECHNICAL SPECIFICATIONSFILED EXAMPLE
It
uses a hydraulic activated device to close and open the caliper arm. The 4
orthogonal independent borehole radii can be measured. After digitalization,
the signals communicate with telemetry / GR tool by Ethernet through10Mcommunication interface board. There are
15 through wires, and 31-pin connectors at up and down heads as per 580
standards
It is composed of electric circuit and caliper. The
housing is made of the PH stainless steel. The pressure balance oil is J26
hydraulic oil.
