F82

Linear displacement sensor for depth measurement. The F82 uses the principle of the pulley that rolls without sliding along a cable stretched between the two ends to be measured. The measurement signal is delivered by an incremental rotary encoder (C82).

P82

The P82 sensor uses the principle of the wheel that rolls on the surface whose displacement is to be measured. The axis of the wheel is integral with an incremental rotary encoder. The assembly is mounted at the end of an oscillating arm of adjustable length. Its axis is mounted on a rubber tension block that can be prestressed to produce a suitable bearing force.

C82

The sensor C82 is an incremental rotary displacement sensor; it is usually mounted at the end of a pulley shaft. It is a robust, waterproof sensor made of stainless materials (bronze, brass, stainless steel).
When mounting, it is essential to provide an elastic coupling between the power take-off and the C82 axis.

Pressure / flow

C16

C16 sensors are robust, watertight, all-metal pressure sensors.
From 2 to 1000 bars.

 

The C16 can be attached to a grout separator SP100, SP200, SP300, SP400, SP500, SP600.

AT50

The AT50 is a flow and air pressure sensor that works according to the principles of Bernouilli's law.
It delivers two measurement signals, a static pressure signal, a signal for the calculation of the air flow.

 

To facilitate maintenance on construction sites, the AT50 is equipped with purge valves to blow all internal lines.

SP

SP separators have a full-flow membrane. They allow the measurement of the pressure in the pipes where grout, concretes, mortars flow.

 

The membranes are made of an elastoplastic material that is particularly resistant to abrasion and chemicals. They make it possible to measure minimum pressures of a few tens of millibars without significant error.

Vibration

CCPVBR

The CCPVBR sensor is a vibration sensor. Mounted at the end of the electric lance of realization of the ballasted columns this sensor delivers several information:
• Amplitude and frequency of vibrations
• Vibrator temperature
• Vibrator tilt
• Buzzer deviation
• Operating time

V16AF50

The V16AF50 sensor is a vibration sensor. It is characterized by high sensitivity and a watertight seal (immersible sensor). The sensor consists of a robust metal enclosure with cable outlet by cable gland. It delivers two types of information: the frequency and the amplitude of the vibrations.

NEMOV BT

The NEMOV BT is a vibration and deviation sensor for the penetration of profiles and tubes. The NEMOV BT is equipped with a Bluetooth radio transmitter and a battery. In the absence of communication (immersed sensor), the measured values are stored in the internal memory of the NEMOV BT, they are transmitted right out of the tool.

Rotation

VR28

The VR28 sensor is a proximity sensor made up of a metal tube with a cable gland outlet: the detection element creates a high-frequency electromagnetic field at the end of the sensor whose amplitude is damped by the presence of a close metal object.

Positioning

Antoise

The ANTOISE sensor measures orientation and positioning with an accuracy of 3 cm.
It consists of two GPS receivers, a GPS receiver called "base" placed above a point of known and exact coordinates.
It corrects the measurement of a second mobile receiver, the "machine" GPS receiver. It is composed of a metal support of one meter equipped with 2 GPS antennas and a housing containing the calculation unit.
One of the antennas is the positioning reference antenna, the other is used to determine the orientation

NORMA2

The NORMA2, coupled with the Dialog, accurately measures the orientation and inclination of the mast on which it is mounted.
It enables an accurate inclination and drilling direction control, independently of the positioning of the machine.
No effort or additional calculation is required, the driller controls the positioning of the mast on the X and Y axes on the screen of DIALOG MX.

Deviation

PRAD

The PRAD is a wireless sensor for measuring the deviation and pressure of the ground, mud or concrete in continuous auger applications, Kelly piles and Soil mixing.
Easy to install, the sensor is equipped with a radio transmitter and a battery. Background information is known when the tool is out of the ground.

Taupi

TAUPI is a sensor for measuring the pile deviation and pressure of concrete in continuous auger applications. It is connected with a separate bluetooth transmitter powered by a battery; the sensor is positioned on the auger. The pressure of the ground and the pressure of the concrete during concreting, as well as the deviation, are transmitted in real time.

Inclination
