[手持式螺丝刀] [固定式自动螺丝刀] [扭矩测量系统]
油压脉冲扳手（断气式）
扭矩范围 5 - 60 Nm / 44 - 530 in.lbs
The pulse tool is a similar design to an impact driver, however with integrated hydraulic pulse unit.
The torque output is controlled by the frequency, (= pulse per minute) and by the adjustment of the pulse unit. When the preset pressure in the pulse unit is reached, which is relative to the torque output, the driver shuts off.
This shut-off transpires prior to achieving the theoretical maximum possible torque (at a certain preset), and therefore no hammer effect occurs, as with standard impact drivers.
The technique of regulating both pressure and frequency, allows a torque accuracy of ±5% standard deviation for pulse drivers with a torque setting even below 10 Nm (88 in.lbs). To enhance the versatility of this tool, the reverse torque is 20 % higher than the seating torque, to assist in rework application.
The pulse tools have the form- and grip design of the reliable MINIMAT-Screwdrivers, especially the straight version, and therefore offers the following advantages:
- low vibration
- low noise level
- ergonomic shape and non-slip housing material
