Evolution of the Smart Probe


STS have been working on the next evolution of our ionising radiation contamination simulators!

Our customers love the basis of our simulation technology which allows artificial contamination to be applied to a surface, spread, transferred and cleaned up -all whilst being monitored with a simulated meter and probe behaving as you would expect surface radioactive contamination to behave.

Our current technology requires the user to have a dedicated instrument that can be converted to accept an STS simulated probe which houses our unique gas detection system. It would of course be beneficial to the customer if they did not have to supply or purchase a meter for modification but could buy a simulated probe that plugs in to their real meter.

STS have to date developed two "smart" probes that will do this - the DP6 for the Thermo RadEye SX and the SBM2D for the Canberra Mip10D. However, these units required extensive reworking of the STS PCB along with additional interfacing circuitry to allow them to work. In the case of the DP6 it meant extensive reworking of the probe body and the SBM2D is built from scratch.

The new development of our contamination PCB has lead to improvements in all aspects, the board is smaller, consumes less power, has a new more powerful and flexible processing chip, has a charging circuit for li-ion cells and can autonomously support an LCD screen and Keypad.

The result of this is that we can now produce “smart” probes for a range of instruments that simply plug and play. The first off the production line will be a new Simulated Ludlum 44-3 Probe for the Ludlum 3000 meter,  a Thermo 44A for the Thermo Mini 900 series and a SPA6 style probe for the 6150AD.

The probe bodies will house the detection system, circuit board, li-ion rechargeable battery and have the appropriate bulkhead connector for the instrument.

Further development will see the production of other smart probes, an interface solution for the HP260 which is too small to house all the simulation components and a generic meter and probe for applications where the user is unconcerned with the make of the meter but wants to demonstrate its application. We will even be able to interface our Safe Series field radiation simulation system so that one meter can potentially offer contamination and field survey solutions.

Final tweaks and testing is almost complete, so the new probes should be available from early 2018.
All in all, this is a huge step for STS and takes our products to the next level of flexibility, operability and practicality.
