Abstract:
(EN) [Problem] To improve measurement of hydraulic pressure in a working fluid chamber of a hydraulic clamp device in such a way that the measurement can be performed without requiring the replacement of a battery or the connection of a lead, ensuring good workability. [Solution] A ring body (50) mounted on the body (12) of a hydraulic clamp device (10) is provided with a wireless pressure sensor device (60) that has: a pressure measurement unit (72) that measures the hydraulic pressure in a working fluid chamber (30) of the hydraulic clamp device (10); a wireless communication unit (76) that outputs, to the outside, a signal indicating the pressure measured by the pressure measurement unit (72); and a power reception unit (78) that wirelessly receives power for the pressure sensor device (60) from the outside.
(FR) Le problème décrit par la présente invention est d'améliorer la mesure de pression hydraulique dans une chambre de fluide de travail d'un dispositif de serrage hydraulique, de sorte que la mesure puisse être effectuée sans nécessiter le remplacement d'une batterie ou la connexion d'un fil, ce qui assure une aptitude au travail satisfaisante. À cet effet, l'invention porte sur un corps annulaire (50) monté sur le corps (12) d'un dispositif de serrage hydraulique (10), qui est pourvu d'un dispositif de capteur de pression sans fil (60) qui comprend : une unité de mesure de pression (72), qui mesure la pression hydraulique dans une chambre de fluide de travail (30) du dispositif de serrage hydraulique (10) ; une unité de communication sans fil (76), qui délivre en sortie, vers l'extérieur, un signal indiquant la pression mesurée par l'unité de mesure de pression (72) ; et une unité de réception d'énergie (78), qui reçoit sans fil de l'énergie destinée au dispositif de capteur de pression (60) depuis l'extérieur.
(JA) 【課題】液圧式クランプ装置における作動液体室の液圧の測定において、電池の交換を行ったり、リード線の接続を行ったりする必要がなく、作動液体室の液圧の測定が作業性よく行われ得るように改善すること。 【解決手段】液圧式クランプ装置(10)の本体(12)に取り付けられたリング体(50)に、液圧式クランプ装置(10)の作動液体室(30)の液圧を測定する圧力測定部(72)と、前記圧力測定部(72)によって測定された圧力を示す信号を外部に出力する無線通信部(76)と、当該圧力センサ装置(60)のための電力を無線によって外部から受信する受電部(78)とを有する無線式の圧力センサ装置(60)を設ける。
