#CMT# #/CMT# The wrench (10) has a torque transmitting shaft (12) with a ratchet head (14) to be provided with the appropriate bit. The handle (22) is hollow and accommodates two piezo elements (26,28) used for generating power to be saved in a capacitor (32). The transformed voltage (34) can also be used for the supply of other devices located at the tool (10). For use the direction is selected with a switch (20) and the appropriate bit attached. The forces applied on the tool (10) are transferred into electric energy and determined with a strain gauge (36). The obtained data are shown on a display (40) at the handle (22). #CMT#USE : #/CMT# The piezo element for power generation in order to supply a torque gauge can be used in a ratchet wrench. #CMT#ADVANTAGE : #/CMT# No external power sources such as batteries are required. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a view at the tool. 10 : Tool 12 : Shaft 14 : Ratchet head 20 : Switch 22 : Handle 26,28 : Piezo elements 32 : Capacitor 34 : Transformer 36 : Strain gauge 40 : Display. |
