Abstract: A detector with a telescoping support tube wherein a measuring probe is arranged at a front of a forward tube element and an electronics unit with a battery compartment, a handle element and axially offset rearward therefrom a U-shaped arm shell with two arm support bars are arranged at a rear tube element, wherein the arm support bars are pivotable relative to the rear tube element. The arm shell is axially moveable relative to the handle element and includes two arm shell elements which are laterally arranged at a support slide and pivotably moveable in a transversal direction of the support tube. The support slide is supported axially moveable by a support rail. According to the invention it is provided that the support slide is fixateable in a disengageable manner at the support rail at various locations through the arm shell elements.

Abstract: A detector with a telescopic carrier/guide rod on which at one end a measuring probe is disposed, whereby the carrier/guide rod comprises at least two anti-twist tubes longitudinally movable and lockable in one another, which form an outer tube and an inner tube, whereby the tubes comprise a linear sliding guide as an anti-twist lock relative to one another. The linear sliding guide comprises at least one longitudinal rib extending inside over the entire length of the outer tube and at least one rib guide extending outside over a partial length of the inner tube on the insertion side of tube end with a recess with which the longitudinal rib engages. The rib guide is formed by a guide sleeve, which is divided in a circumferential direction.

Abstract: A detector with a telescopic carrier/guide rod at which a measuring probe is disposed at one end, wherein the carrier/guide rod features at least two tubes longitudinally movable inside one another, in which respectively two tubes disposed adjacently in radial direction form an outer tube and an inner tube, whereby the respective outer tube at its overlapping tube end facing the measuring probe features a clamping means for engaging the inner tube. In accordance with this invention, the clamping means is formed as a clamping device that features a profile clamp with a quick-locking device. The profile clamp comprises a holding ring with two half shell-shaped clamping ring segments that are interconnected flexibly on one side and on the opposite side they can be clamped together with a clamping lever.

Abstract: A hand-held metal detector for checking persons with a probe section serving for housing a metal detection probe implemented as a detector coil, followed by a shaft serving as a handle that holds display elements and operating elements as well as metal detection electronics. In addition to the metal detection probe, the hand-held metal detector is equipped with a radiation detection probe with associated radiation detection electronics, with the radiation detection probe preferably formed by a scintillation detector. The metal and the radiation detection electronics are coupled with a differentiated signaling and alarm system.

Abstract: In a method and a measuring device for metal detection with the use of a coil arrangement the spatially offset transmitting coils are controlled with pulse sequences of different pulse patterns. The receiving coils associated with the transmitting coils are scanned with respect to the received measuring signals with a scan pattern corresponding to the respective associated pulse pattern. It is therefore possible to control simultaneously all transmitting coils and to provide a spatial determination of a metal object located in a throughgoing region of a gate frame.

Abstract: The locating system for locating magnetic objects in the ground includes a series of position transmitters arranged at predetermined positions along a measurement path; a magnetometer probe movable by an operator over the measurement path and including a device for generating measured magnetometer signal values; a position detector including a sensor movable over the measurement path together with the magnetometer probe, the sensor producing a sensor position signal value when the sensor passes over each position transmitter along the measurement path and a data receiving and analyzing unit connected with the position detector to receive the position signal values and with the magnetometer probe to receive the measured magnetometer signal values independently of the position detector. The data receiving and analyzing unit then accurately determines a functional relationship between magnetometer probe response and the magnetometer probe position to more accurately locate the magnetic objects in the ground.

Abstract: A metal detector is proposed, in which field coils and receiving coils are arranged on either side of a zone to be monitored. In order to bring about a more uniform sensitivity distribution within the zone to be monitored, alternately the field coil on one side and the field coil on the other side is excited for radiating a magnetic field.
