  • Light weight
  • Easy to use
  • Simultaneous Max & Min modes
Heritage GeoPhysics is pleased to introduce its new multi-frequency electromagnetic profiling system, PROMIS-10, bringing improved productivity with its fully incorporated data logger and its multi-components receiver sensor.

PROMIS-10 is the ideal geophysical tool for locating conductive targets such as: fractured zones for groundwater exploration, mineralized veins for mineral exploration.

The operator at the receiver fully controls the transmitter through the cable link. After each new reading, the profile curve is updated on the receiver graphic display.

PROMIS-10 transmitter features ten frequencies from 110 hertz up to 56320 hertz and is designed for transmitter-receiver spacings of up to 400 meters.

PROMIS-10 receiver features a three-components sensor allowing to simultaneously acquire data in the Max and Min coupling configurations. The additional perpendicular component provides information on the target strike.

The optimized design of the PROMIS-10 provides unmatched characteristics both for the transmitter (lighter but more powerful) and for the receiver (versatile and easy to handle).

Features:

  • Ten frequencies:110, 220, 440, 880, 1760, 3520, 7040, 14080, 28160 and 56320 hertz
  • Coil separation: Any value between 10 and 400 meters thanks to digital compensation of primary field
  • Reference cable: Lightweight unshielded two twisted conductors teflon cable with kevlar thread, for wide operation temperature range and higher strength
  • Standard lengths: 50, 100, 150, 200 and 400 meters. Other length on request (between 10 and 400 meters)
  • Intercom: Voice communication through the reference cable
Receiver specifications:
  • Receiver EM sensor: choice of 1, 2 or 3 axis coil assembly
  • Parameters measured: in-phase and quadrature components of the secondary magnetic field (in percent of primary)
  • Tilt sensor: measurement over 2 or 3 axis
  • Display: graphics LCD 128 x 64 pixels
  • Data storage: 1 Mbyte Flash memory (optional 32 Mbytes)
  • Power supply: NiMh 4.8 V - 4 Ah battery
  • Operating temperature range: -40 to +70 °C
  • Weight: 3 kg with one component sensor, 4 kg with three components sensor
Transmitter specifications:
  • Transmitter coil: optimized for wide frequency range, light (8 kg)
  • Tilt sensor: measurement over 2 axis
  • Transmitter console: remote-controlled by receiver through reference cable, or operator-controlled with four keys keyboard
  • Console weight: 3 kg
  • Display: LCD with 4 lines of 16 characters each
  • Power supply: NiMh 12 V - 24 Ah battery in belt pack (3.5 kg) providing more than one day of operation in most conditions

Promis-4, EM PROFILING, Geometrical sounding

  • Light weight
  • Easy to use

  • Promis-4, EM Profiling Heritage Geophysics is pleased to introduce its new electromagnetic profiling system, PROMIS-4, bringing improved productivity with its incorporated data logger and superior coil design. This system offers a less expensive alternative to the ten frequency Promis 10 system.

    PROMIS-4 is the ideal conductivity mapping instrument for investigations in the 10 to 100 meters range:

    • groundwater contaminant plumes mapping
    • groundwater exploration in fractured, faulted or weathered hard-rock

    Promis4 PROMIS-4 features four transmitter-receiver spacings (10, 20, 40 and 80 meters) for electromagnetic geometrical sounding. It can be operated both in the vertical and horizontal coplanar loops modes so as to optimize the inductive EM coupling according to the target geometry.

    PROMIS-4 features two frequency settings (standard and alternate) to allow better accuracy in highly resistive areas where higher frequencies should be used.

    INTERCOIL SPACINGS 10 m 20 m 40 m 80 m
    STANDARD FREQUENCIES 7.04 kHz 1.76 kHz 0.44 kHz 0.11 kHz
    ALTERNATE FREQUENCIES 28.16 kHz 7.04 kHz 1.76 kHz 0.44 kHz

    T-VLF System, Digital Multi Station Acquisition

    T-VLF System, Digital Multi Station Acquisition

    Features:

    • Lightweight system weighs less than 6kg.
    • Sensor unit is back-mounted and has a hand held controller unit.
    • VLF radio wave receiver with frequency range 10 to 30kHz.
    • Serial link for data transfer to microcomputer or printer.
    General:

    No orientation of the operator with the direction of the transmitter is required. Three magnetic sensors measure the components of the VLF field. The sensor unit has two inclinometers to correct for tilt.

    The microprocessor automatically takes the measurement. The frequency is keyboard selectable and two frequencies can be measured at the same time.

    Low noise magnetic sensors and digital filtering produce good measurements even in areas where primary fields are weak. A quality factor is given at each measurement to control the quality of the data

    Operation:

    The classical kilt angle mode, based on the measurement of magnetic-only components, is used to prospect conductive dyke-like structures that generally correspond to weathered or mineralized zones.

    The resistivity mode is based on the measurement of magnetic and electric components. When working with the resistivity mode, a short electric line and two metaDic electrodes are used. Applications include the prospecting of resistive dyke-like structures, and geological mapping (structural studies).

    Display:

    A large graphic display gives the operator complete information about the measurement: Tilt angle and ellipticity, with their Fraser derivative values (mode 1); resistivity and phase (mode 2). The tilt or resistivity curve is automatically plotted after each station to enable the operator to make a first analysis of the measurements.

    Internal Memory:

    All measured parameters, with frequency value, station and line number, are stored in a solid state memory system capable of containing more than four thousand measuring stations. At the end of the day, or on the field site, data can be transferred to a printer or microcomputer.

    Specifcations:

    VLF radio wave receiver with frequency range 10 to 30kHz.

    Fully automatic measurement through microprocessor control.

    Frequency keyboard selectable in 100Hz steps. Two frequencies can be measured at the same time.

    Two measurement modes:

    • Tilt angle mode—three magnetic sensors with two inclinometers (+ / - 45°).
    • Resistivity mode—one magnetic sensor with one electric line.
    Large graphic display (240 x 64 points), with display of:
    • Frequency, station and line numbers,
    • Ellipticity and tilt angle (mode 1), or resistivity and phase (mode 2),
    • Quality factor for each measurement,
    • Automatic curve plot for raw or Eraser derivative values.
    Data storage in solid state memory.

    Serial link for data transfer to microcomputer or printer

    Standard Components:

    Sensor console, logger, system software and instruction manual.
