装置。 This reciprocating motion number remote indicating device is a device that displays the reciprocating motion number from a reciprocating machine located in an explosion-proof area to a remote control room located in a non-explosion-proof area. This remote indicating device converts the movement of reciprocating machinery into air pressure, and an air pressure detector 6 installed in a non-explosion-proof area via an air pipe 7.
Piping up to. Fluctuations in air pressure are converted into on-off electrical signals using a switch built into the air pressure detector. This is an explosion-proof reciprocating motion remote indicator device in which the electric signal is processed by a converter built into a remote indicator 7 in a remote control room and displayed digitally or analogously.
