WS05C Area Monitors
Specifications
GRAETZ WS05C-1 / C-2 / C-3 Area Monitors
The area monitors WS05C-1 / WS05C-2 and WS05C-3 are stationary room monitoring systems for the dose rate measurement of γ-radiation and X-rays, preferably used for the permanent monitoring of isotope laboratories, radiotherapy rooms, storage rooms for radioactive materials, etc..
| WS05C-1: | Area monitor (1 measuring channel) with RS232-interface for the operation with any probe of the GRAETZ-programme. |
| WS05C-2: | Area monitor (2 measuring channels) with RS232-interface for one measuring channel, for the simultaneous operation of max. 2 different or similar probes – any of the GRAETZ-programme. |
| WS05C-3: | Area monitor (3 measuring channels) with RS232-interface for one measuring channel, for the simultaneous operation of max. 3 different or similar probes – any of the GRAETZ-programme. |
Each measuring channel indicates the measured values on a digital, illuminated LCdisplay (60x30 mm). For each measuring channel four individual dose rate alarm thresholds are free programmable over the whole measuring range of the connected probes.
When using γ-probes, the dose rate shown on the LC-Display is Sv/h. When an end-window probe for α-/β-measurements or a NaI-scintillation probe for β-/γ- measurements is connected, the measured value is displayed in cps. Additionally to the digital display, the dose rate is also indicated in analog form by a logarithmic bar graph.
The instrument is autoranging. When a measuring channel triggers a dose rate alarm, the integrated alarm light of the WS05C gives an optical and acoustical alarm. In the standard version: green --> “ready for operation”, orange --> “alarm threshold exceeded” / red --> “error” (e.g. defective probe). The red LED situated above the display indicates by which measuring channel the alarm has been triggered.
For connecting the WS05C with a computer, an RS232-interface for one measuring channel is available
Options
• Relay output for an additional external alarm lamp for each measuring channel or a potential free relay output for each measuring channel instead of the relay output for the external alarm lamps (max. switching voltage/current: 24V, 20 mA).
• Acoustic alarm disconnectible: only triggered when an alarm threshold is exceeded and the monitored room’s door is open.
• Emergency power supply (300W) for the uninterruptible operation of the WS05C in case of mains failure.
• External alarm lamps (optical/acoustical)
• Probe cable (standard length: 1,25 m), extension up to 100 m
• Special versions upon request
