Mirion Technologies OEM User Manual

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

○ 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
