WRPIC100 Wide Range Ion Chamber

The Apantec model WRPIC100 is a post-mounted Wide Range Area monitoring probe designed for detecting ambient or bursts of gamma radiation in applications such as: perimeter, gateway or waste site monitoring. By special design and build, the WRPIC100 offers enhanced functionality in environments characterized by high temperature and humidity.

The WRPIC100 uses Apantec's advanced ion chamber design to detect radiation fields from background to accident levels. The WRPIC100 uses a solid state electrometer instead of the traditional current to frequency converter, which provides an additional decade of sensitivity. In the WRPIC100 all the electronics including the solid-state electrometer, microprocessor board and a high voltage board are packaged in a sealed box underneath the flange plate. A temperature sensor is placed inside this box and an optional thermoelectric cooler and fan can be used for extreme environments. The WRPIC100 can operate as a stand-alone unit, directly linked to a central computerized system or in connection with a ratemeter such as Apantec's RM1W. Additionally, data from multiple WRPIC100's can be easily managed with the use of Apantec's DORIS database software. The software enables collection, customized graphical display, analysis, reporting and distribution of real time or historical data.

RATEMETER INTERFACING
The Apantec WRPIC100 uses a solid-state electrometer to convert the ion chamber output current into a signal suitable for counting by the probe's internal interface card. The interface card converts the measured activity signal into a serial communications format (RS485 or TCP/IP) for communication to a separate RM1W or RM1R display and control unit, or it can be interfaced directly to the D.O.R.I.S. software computer. This removes the need to send low current level signals (which can be affected by signal line capacitance) or voltage signals (which can be affected by EMI/RFI signal line interference) over long distances.
D.O.R.I.S. - Display of Radiological Information Software provides real-time data reporting and control through a user-friendly graphics display with an easy to use operator interface system.
Data is collected, analyzed, displayed and recorded in real-time
