The area monitors of the type "WS 05 C" are stationary room monitoring
systems for the dose rate measurement of gamma radiation and X-rays,
preferably used for the permanent monitoring of isotope laboratories,
radiotherapy rooms, storage rooms for radioactive materials, etc..
The "WS 05 C" is available in the following versions:
-
WS 05
C-1
Area monitor (1 measuring channel) with RS-232-interface for the
operation with any probe of the GRAETZ-programme.
-
WS 05
C-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.
-
WS 05
C-3 (see picture)
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 (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 gamma
probes, the dose rate shown on the LC-display is Sv/h. When an
end window probe for α- and β- measurements or a
NaJ-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 "WS 05 C" gives an optical
as well as an acoustical alarm. In the standard version: orange for
"alarm threshold exceeded" and red for "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 "WS 05 C" 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 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).
Disconnectible acoustic
alarm (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 "WS 05 C" in case of
mains failure.
Integrated alarm lamp
(optical/acoustical) for the indication of the following conditions:
green: "ready for operation"
orange: "alarm threshold exceeded"
red: "error"
External alarm lamps
((optical/acoustical)
Probe cable
(standard length: 1,25 m), extension up to 100 m
