FEATURES
OEM Gamma Sensor
Area and Particulate Monitors - Area Monitor
OEM GAMMA SENSOR
Electronic Dosimeter Module
The OEM GAMMA SENSOR features at energy
response to X-rays and gammas from 50 keV to 7 MeV
and a linear response for dose rate from natural
background up to more than 10 Sv/h.
The OEM GAMMA SENSOR provides dose, dose rate,
alarms, digital inputs (3) and digital ouputs (3)
● Slave mode: communication by I2C
or UART 9600 bauds
● Autonomous mode: essential parameters
sent periodically (1 to 63 seconds) on UART 4800
serial link
● Parameters and dose saved in EEPROM

○ Dose: 1 μSv to 10 Sv (0.1 mrem to 1000 rem)
○ Dose rate: 10 μSv/h to 10 Sv/h (1 mrem/h to 1000 rem/h)
○ For lower dose rate, please contact Mirion Technologies
○ Saturation above 10 Sv or 10 Sv/h
● Linearity:
○ <± 15% up to 1 Sv/h (100 rem/h)
○ <± 25% up to 10 Sv/h (1000 rem/h)
● X and Gamma energy range: 50 keV to 7 MeV
● Accuracy Hp(10) module alone:
○ <±5% (
○ <±10% (
137
Cs : 1 mSv/h) (100 mrem/h)
241
Am: 0.2 mSv/h) (20 mrem/h)
ELECTRICAL CHARACTERISTICS
● 3.3V 1.2 mA for I2C mode, 0.4 mA for UART mode
MECHANICAL CHARACTERISTICS
● Dimensions:
○ Ø: 40 mm (1.6 in)
○ h: 4 mm (0.16 in)
● Weight: < 5.5 g (0.19 oz)
● LED fl ashing is programmable for:
○ Each 4 or 8 pulses
○ Each μSv (0.1 mrem)
○ Each 10 μSv (1 mrem)
○ Each 100 μSv (10 mrem)
● 2 Connectors:
○ one for power supply, I2C or UART serial link, and
alarm
○ one for digital inputs and outputs
CUSTOMIZATION
● Setup can be accessed by authorized user
with OEMMASS software
ENVIRONMENTAL CHARACTERISTICS
● Temperature range:
-10°C to +50°C (14°F to 122°F)
● Storage: -30°C to +71°C (-22°F to 160°F)
● EMC: complies and exceeds standards by a large
margin
FUNCTIONAL CHARACTERISTICS
● Alarm report output:
○ no dose rate alarm or pre-alarm:
- alarm output signal normally low
○ dose rate «pre-alarm»:
- alarm output signal oscillates 0.5 Hz
○ Dose rate alarm: alarm output signal goes high
○ programmable threshold for dose rate pre-alarm and
alarm
