FIELD: mining.
SUBSTANCE: electronic probe is offered which contains a metal power supply compartment 1 and a plastic housing 2 conjugate to it where a measurement unit 3, and also a signal processing unit 4 designed as a microcontroller unit, and a magnetic antenna 5, which are filled with a moisture resistant compound. The measurement unit 3 comprises a tilt sensor 6 of longitudinal axis with reference to the horizon, a roll sensor 7 and a pulse stabiliser 8. The plastic housing 2 is made of multilayered fibreglass the inner layers of which are made of vitreous fibres with longitudinal and orthogonal orientation in the housing structure, and external layers are made of vitreous fibres with diagonal orientation. The magnetic antenna 5 and the measurement unit 3 have multilayered high-adhesive moisture resistant coating 11, and the microcontroller unit 4 - the coating 12 of varnish with low adhesive ability to the moisture resistant coating of the measurement unit 3 and the magnetic antenna 5, and they are filled during assembly with the moisture resistant compound 13.
EFFECT: improvement of the probe reliability due to strengthening of the housing and reliable sealing of the main electronic units.
