WELL SLOPE ANGLE-DATA TRANSMITTER Russian patent published in 1998 - IPC

FIELD: measurement technology. SUBSTANCE: circular space 3 of body between external 1 and internal 2 cylinders is filled partially with liquid metal 4. Outer surface of cylinder 2 carries resistor element 5 which engages liquid metal 4 electrically in process of measurement. Liquid metal is heated by means of electric heater to temperature exceeding its melting temperature. Electrical leads 7, 8, 9 of angle-data transmitter are connected, respectively, to resistor element, electric heater and cylinder 1. Zenith angle value is determined by measuring the electrical resistance of open part of resistor element 5 and using calibration graph ϕ^o= f(R). EFFECT: higher measurement results. 2 cl, 2 dwg
