Even higly mineralised ore has a much lower conductivity than refined metal. Therefore, both magnetic and non-magnetic metals are efficiently detected while so-called product effects are virtually eliminated.

The pulsed induction technique intesifies the generated electromagnetic field for very short time intervals. Measurements are taken many hundreds of times a second during the concentrated energy pulse which provides a very high signal-to-noise ratio without the heating and stress of the conventional continuous wave method.


Ease of set up and use

Complete programming, including setting for alarm delay, alarm duration, sensitivity scale factor and splice detector duration and threshold, is accomplished by turning dials on the control panel.

Reliable operation

Solid-state IC’s ensure long operating life and trouble-free service. Circuitry has been been designed for automatic splice protection (ASP). Resident diagnostic monitor uses LED’s to indicate the operation status of the circuit.


Coil units are made of monolithic, high-impact resistant fibreglass (reinforced) to withstand damage even by frost chunks or other types of over-capacity loads. The rigid framing and other system components are made to stand up under the harshest conditions. Steinert detectors are built so well they come with a 3 year parts and labour warranty protection from manufacturing defects.

Convenient repair

Relays and circuit models are field replaceable.

Sanwest Pty Ltd was established in 1987 when the Equipment Division of Mitchell Cotts Engineering was sold to the then Manager Mr Ken Hollick. With other existing personnel who had a long association with Australian industry, the new company was established to continue marketing the products to the Australian mining and process industries.
