FIELD: measuring equipment.

SUBSTANCE: invention relates to the area of measuring equipment and is intended to control pressure of gaseous and liquid substances in industrial and other processes in explosive environmental conditions. The explosion-proof electric contact manometer includes a body and a shell, a housing of an electrical lead-in, a composite holder with a Bourdon tube (a sensitive element), and an outlet tube. The composite holder is comprised of a lower part and an upper part installed within the body with an outlet tube, wherein the lower part of the holder is mounted on the outlet tube outside of the body and is sealed with the outlet tube at the external outlet thereof, wherein a hole with a diameter corresponding with the diameter of the outlet tube is made for the outlet tube in the body. The Bourdon tube (the sensitive element) is connected with the outlet tube through the upper part of the holder.

EFFECT: technical result is increased reliability of operation of the manometer in explosive conditions by providing sealed connection of the upper and lower holders and explosion-proof connection of the holders with the body without overcomplication of the design and with maintained simplicity of use.
