Stationary room monitoring system from GRAETZ for dose rate measurement of gamma radiation and X-rays preferably used for permanent monitoring of isotope laboratories, radiotherapy rooms, storage rooms for radioactive materials, etc.
WS05C-1: Area monitor (1 measuring channel) with RS-232 interface for the operation with any probe of the GRAETZ-programme.
WS05C-2: Area monitor (2 measuring channels) with RS-232 interface for one measuring channel, for the simultaneous operation of max. 2 different or similar probes - any of the GRAETZ-programme.
WS05C-3 (see illustration): Area monitor (3 measuring channels) with RS-232 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 LC-display (60 mm × 30 mm). For each channel four individual dose rate alarm thresholds are free programmable over the whole measuring range of the connected probes.
When using gamma probes, the dose rate is displayed in Sv/h. When an end window probe (α-/β-measurements) or a NaI-scintillation probe (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 as well as an acoustical alarm. In the standard version:
green "ready for operation",
orange "alarm threshold exceeded”,
red "error message" (e.g. probe failure)
The red LED situated above the display indicates which measuring channel triggered the alarm.
For connecting the WS05C with a computer, an RS-232 interface for one measuring channel is available.
relay output for an additional external alarm lamp for each measuring channel or apotential free relay output for each measuring channel instead of the relay output for the external alarm lamps (max. switching voltage/current: 24 V, 20 mA)
switching off acoustic alarm (only triggered when an alarm threshold is exceeded and the the door of the monitored room is open)
emergency power supply (300 W) for the uninterruptible operation of the WS05C in case of mains failure
external alarm lights (optical/acoustical)
probe cable (standard length: 1,25 m), extension up to 100 m
special versions on demand
