The JCS RMS30

Intelligent radiation monitor system

Description

Frame Left

The RMS30 is a versatile, intelligent, dual channel monitor.

Flexibility underpins the operation of the RMS30 where sample time, counting period, alarm thresholds (per probe) can be defined by the operator.

The RMS30 can be portable (battery-powered) or mains-powered, bench or wall-mounted, have variable cable lengths for probes and even a remote alarm module to accommodate a multitude of measurement scenarios.

The design philosophy behind the instrument is to allow the operator to use a particular probe type (with single or dual channel measurements), or the flexibility to specify a different detector type. The RMS30 allows the operator to define how the probe data is displayed in real-time (sV/h, CPS or rem/h) and also how the data is then stored in the internal memory. All logged data can be accessed via USB to a PC where information is stored in a simple to manage spreadsheet.

The RMS30 is designed to accept a growing number of JCS designed probes and accessories, which will further extend how and where the instrument can be deployed.

RMS30 System Probes

The RMS30 operates a growing range of custom designed gamma & neutron probes to suit a wide range of measurement applications. Simplicity and ease of operation underpin our design philosophy and deployment methodology.

Each probe type is immediately identified and displayed by channel and serial number as it is connected to the RMS30 (it is possible to run 2 different probe types in a single measurement session).

Although simple in operation, the RMS30 range of probes and accessories are intelligent in design and function. The communication between the probes and the electronics allows the RMS30 to immediately recognise and enable the attached probe which is optimised for measurement in its particular range.

Probe 106 – Neutron Monitor

Continuing the JCS family of smart probes, the RMS30-106 Neutron Detector measures neutron radiation and calculates the dose rate or count rate, depending on the mode selected. The probe may be operated in in either counts per second or dose rate mode. In dose rate mode the units may be set to either Sv h-1 H*(10) or mrem h-1

The RMS30 Intelligent Monitor – Now with networked management capability

Frame Left

We are pleased to announce that the RMS30 can now connect to an internal IT network infrastructure, allowing our customers to install the RMS30 and its probes in a strategic locations, while allowing an operator to remotely operate and view the RMS30 live data. This allows the RMS30 to become a simple, yet versatile Low Cost installed area radiation dose monitor with a variety of neutron, gamma and x-ray measurement capabilities.

RMS30-PL1 – Cable Position Indicator

Frame Left

The RMS30-PL1 Cable Position Indicator is part of a family of smart sensors for the RMS30 Intelligent Monitor. The cable position indicator is used in conjunction with any of the range of RMS30 smart probes, and measures the deployment of cable into storage compartments, bores and other vertical drops. The RMS30 monitor reads the data from the sensor, via the RS485 communications connection, and displays it on the relevant channel pane.

Alarm Module

The RMS30-AL1 Alarm Box is an externally connected alarm unit with both audio and visual alarm indications. Large LEDs on the front panel provide a clear indication of alarm state. The audio alarm is provided by an industry standard sounder, ASKARI panel process sounders by Fulleon Technology. When activated the sounder is set to a continuous 970 Hz tone.
