A wall detector () for detecting an object () embedded in a substrate () includes a detection antenna () for introducing broadband, high-frequency alternating electric fields () of a measurement frequency (f) in the substrate (); a measurement system () connected to the detection antenna () for measuring the delayed interaction of the alternating fields () with the object (), a calculation device () for detecting the object () based on the measurement signal and for determining the associated depth information, and a permittivity measurement device () with at least one auxiliary potential plate () for measuring the permittivity measurement signal of the substrate at a permittivity measurement frequency (f) that is a lower than the measurement frequency; and an associated measurement method.

Wall detector

A detector () for detecting embedded elongate objects () has an evaluating unit (), a computing device (), an output device (), and a handheld measuring head () which can be moved over a surface (F) and which has a path a detector () and a transmitting-receiving unit () with an antenna (). At least two antennae () are spaced apart from one another along the surface (F), and the distance (A) therebetween, measured over the surface (F), ranges between 5 cm and 50 cm.

Detector for embedded elongate objects

A handheld scanning subsurface detector () includes a detector module () and a computing unit () located in handheld housing (), a guide () for guiding the detector module () at a predetermined distance over a to-be-analyzed wall surface (), at least one path sensor () connected to the computing means () and connected, in a controlling manner, to the detector module () by controlling means (). A corresponding control method is also described.

Handheld scanning subsurface detector

A control process for an at least partially axially hammering and rotating electric hand-held machine tool () in which an electromagnetic clutch () arranged in the flow of force between an electric motor () and a tool receptacle () is controllably connected to computing device () connected to sensors (), wherein the clutch () is repeatedly alternately opened and closed in at least one process step controlled by the computing device ().

Process for controlling an axially hammering and rotating electric hand-held machine tool

An explosive powder charge-operated setting tool having a drive piston ( ) for driving a pin-shaped nail ( ) in a constructional component in a single drive-in step, and a control circuit (I) for controlling a setting depth (T) and including control electronics ( ), a set point generator ( ) for setting the setting depth (T), a position-determining sensor ( ) for determining a position of a lower dead point (uTP) of movement of the drive piston ( ), and a regulator ( ) for an automatic adjustment of a motion energy of the drive piston; and a method of controlling the setting depth (T).

Setting tool with a setting depth control

The method of and a device for using this method, on equipment or assigned to equipment for working a material, for investigating and identifying the nature of the material, which is to be worked and for making available at least one operating parameter for the optimized pre-setting of the working equipment, provides for the use of a sensor, preferably assigned directly to the working tool, such as a hammer drill, in order to detect shock waves generated or induced in the tool. From the shock wave signal measured, at least one distinguishing feature characteristic of the material to be worked, is extracted and evaluated for the comparative classification of the material by means of an algorithm. Preferably, an external force, especially the contacting force, acting on the working equipment, is taken into consideration for the algorithmic evaluation.
