The SA-20-2 probe for measurement of contamination is designed to be used with any CSP™ host device. It can be a handheld CSP instrument, a single PC with dedicated software or a networkable system.
The SA-20-2 probe for measurement of contamination is designed to be used with any CSP host device. It can be a handheld CSP instrument, a single PC with dedicated software or a networkable system. The SA-20-2 probe connects to host device using either a specific cable or any of the CSP-COM modules to match the system conjuration (wired or wireless). Its 20 cm2 ZnS detection area makes it an ideal tool for counting alpha wipes, open wounds and filter papers.
The SA-20-2 probe is part of the Canberra™ SMART Probe (CSP) family. It includes all key components of hardware circuitry (high voltage power supply, amplier, discriminator, etc.). Also, the intelligence associated with controlling those components is located in the probe – that is control and storage of key parameters, settings, calibrations, probe ID, alarm settings (10 values for each unit to display with default setting), etc. Thus the probe is a fully integrated subsystem taking and transmitting the measurement to the instrument, which is used for display. With high voltage and digitization of the data occurring in the probe rather than the instrument, measurement quality is no longer dependent on external device quality (cable, host instrument). Moreover, a CSP probe is using a serial protocol to communicate with host, which can be an instrument or a PC. Calibration and QA measurements can be performed directly with the probe, without using an instrument, by connecting the probe to a computer with the Canberra Smart Probe Software (CSPS™), allowing your instruments to remain deployed in the field. Once calibrated, the SA-20-2 unit is ready to be used as a plug and play probe to start a QA measurement in CPM, DPM, DPM/100 cm2 or c/s, Bq, Bq/cm2. The SA-20-2 probe connects to survey meter via a 1.5 meter or 20 meter CSP cable. The SA-20-2 unit includes a hand screwed protective grid that is very easy to remove for decontamination. The SA-20-2 probe is able to store up to 1000 data points from a data- logging procedure handled via the host instrument. These data are: Index, date/time, measurement value, selected unit and counting time. The SA-20-2 probe can be upgraded (probe’s firmware) via CSPS, a USB cable and a PC.
