Syscal Monitoring Unit (SMU)

1 May 2017

The Syscal monitoring Unit is an automated system designed to allow the operator to remotely manage the recharging of the Syscal Pro transmitter and receiver batteries during a monitoring survey.

The SMU connects the Rx and Tx batteries to an alternative source of power (solar panel, wind turbine, isolated charger, ethanol fuel cell) when the Syscal is not acquiring. During the acquisition, the external power supply is remotley disconnected from the Tx and Rx batteries to avoid any leak of current that would perturbate the measurements.

WiConnect connects directly to the Com Port interface on the top of the instrument allowing the operator to configure the instrument and monitor measurements in real-time via a simple web browser, on any device.

To accompany the WiConnect IRIS Instruments have released new versions of Prosys II, Electre Pro, Fieldview and Comsys Pro with wifi connectivity tools.

Desktop Shield for GT40

15 March 2017

The range of applications the GT-40 and GT-40S gamma ray spectrometer has been extended by the release of a desktop laboratory shield. The new shielding combines steel and lead materials to get maximum shielding efficiency and minimum weight.

With around 100 kg of mass can be located on a desk. In combination with multicomponents analysing method used in GT-40/GT-40S creates an alternative to big laboratory gamma spectrometers.

New Logging Boom

24 February 2017

Mount Sopris recently released a cost-effective and versatile hitch boom that conveniently fits into a standard 2-inch by 2-inch hitch receiver – ideal for 4x4 vehicles and Vans.

The boom features simple adjustments that make it easy to position the boom over the borehole. These include an adjustable reach, making it possible to extend the boom up to 44 inches beyond the adjustable support mast. The boom also effortlessly swivels from side-to-side, secured by a spring-loaded pull pin. The maximum capacity of the boom is 500 lbs. in its standard configuration (as shown), and 250 lbs. in the extended reach position.

Its rugged powder-coat and galvanized finishes can tolerate the harshest conditions that you may experience in the field. You’ll also appreciate the cable wiper that will keep your wireline, winch, and vehicle cleaner.

CG5 Tear

9 January 2017

The Scintrex CG5 Autograv has been the leading relative gravity meter for commercial mineral exploration and ground engineering studies for over a decade. In that time we have developed robust test procedures to ensure the instruments are operating within manufacturers specifications. It is our policy that all CG5s are setup to record data when they are not in service. This allows us to analyse the noise floor of each instrument and manually calculate the drift correction.

On returning to work after the new year bank holiday the data from all CG5s -which were not out on rental- was downloaded from the instruments. On analysing the data we noticed a significant tear in the measured gravitational acceleration at exactly 11:59pm on the 31/12/2016. The amplitude of the tear varied for each instrument, but the tear is always positive. The building was empty at the time, and the tilt values showed no environmental event which would have caused such a DC shift in the data. The measurement stability did not change after the tear event. The tear was present on all instruments.

Through further analysis we deduced the tear was caused by the new tide correction modal which took effect on the 1/1/2017. Scintrex corroborated our findings. Although the tear has not affected the performance of the instruments, the tear was only discovered because we analyse the data before perform a manual drift correction. Those who use the automated drift correction might find the new drift value is significantly different from the previous value.

Action to be taken:

  • If the CG5 was set to perform an automatic drift correction spanning the dates of 31/12/2016 and the 1/1/2017 we suggest the new correction is disregarded and the instrument is placed by on drift correction for a further 24 hours.
  • If the instrument was set up for a manual drift correction the operator can calculate the new drift correction from measurements recorded after 1/1/2017. The performance of the instrument will not be affected.
