CEL-320 & 360 Noise dosimeters

An overview of the range of Casella CEL Personal noise dosimeters

what models are available
What models are available?
  • CEL-320 personal noise dosimeter
  • CEL-320S sound level meter
  • CEL-360 logging noise dosimeter
  • CEL-360S logging sound level meter
  • There are also intrinsically safe models available for all of the above versions
cel 300 models
CEL-300 models
  • Common features include
    • Cable microphone
    • Sealed keypad
    • Optional stalk microphone
    • Memory for 50 separate runs
    • Keypad lock
    • Long battery life
what model is best
What model is best?
  • For simple measurements of the overall noise exposure the CEL-320 is sufficient
  • For a more comprehensive understanding of the noise exposure using the time history or data logging function then the CEL-360 is better
cel 320 instrument main features 1
CEL-320 instrument main features 1
  • 3 measurement ranges (30 – 140 dB)
    • Low 30 – 100 dB
    • Med 50 – 120 dB
    • High 70 – 140 dB
  • 2 frequency weighting
    • A and C
  • Separate peak frequency weighting
    • Lin or C
cel 320 instrument main features 2
CEL-320 instrument main features 2
  • 3 time weightings (responses)
    • Slow, Fast and Impulse
  • 4 amplitude weightings (exchange rates, Q factor)
    • Q = 3, or 4 or 5 or 6
  • 2 simultaneous threshold levels
    • Normally 80 and 90 dB
  • Single criterion level
    • Settable from 80 to 90 dB
cel 320 instrument main features 3
CEL-320 instrument main features 3
  • Storage space in memory for up to 50 separate measurements
  • Every run tagged with start date and time
  • Calibration information stored with run
    • Pre run and post run date, time and level
  • Measures the overall total noise during run as a single figure for simple comparison against standards
cel 320 instrument main features 4
CEL-320 instrument main features 4
  • Preconfigured named SETUPs for quick start using most popular settings
    • OSHA, MSHA, DoD, ACGIH, ISO85, ISO90 & METER
    • Just select from the list, load and run to begin
  • Icon in display shows run has started
  • Lock keypad and wait until the end of the run
  • Halt run, readout results from memory
what measurements are stored 1
What measurements are stored 1?
  • For OSHA recordings
    • Actual noise dose%1
    • Projected 8 hour noise dose%1
    • Calculated TWA1
    • Where results include noise above lower threshold level 80 dB
    • Same set for noise above upper threshold level 90 dB
what measurements are stored 2
What measurements are stored 2?
  • Time average noise level
    • LAeq with Q=3 exchange rate
    • Lavg with Q=5 exchange rate
  • Sound exposure level
    • LAE with Q=3 exchange rate
  • Maximum noise level
  • Minimum noise level
  • Peak noise level
what measurements are stored 3
What measurements are stored 3?
  • Up to 5 statistical percentiles (LN%)
    • LN10%
    • LN50%
    • LN90%
    • LN95%
    • LN99%
  • Used to describe the variation in the noise level from a distribution table stored during the run
what other outputs are available
What other outputs are available?
  • Results can be viewed in display using DATA key
  • Results can be directly printed as a single page report
  • Results can be downloaded to standard CEL software package
what are the benefits of the cel 360
What are the benefits of the CEL-360?
  • Automatic recording using delay start/stop timers
    • Up to 16 sets of on/off times can be programmed into dosimeter
  • Run lengths of fixed duration
  • Storage of time histories to profile the noise during the run
    • Allows the time variation of noise levels to be displayed on the pc from the recording
what sampling intervals can be used
What sampling intervals can be used?
  • CEL-360 can sample noise levels
    • From 1 second fastest to 1 hour longest
    • Total memory size is over 220,000 data points
  • How long can a recording last
    • Over 60 hours for 1 value every 1 second
  • How many parameters can be sampled
    • Up to a maximum of 10 parameters can be stored every sampling interval in a run
what are the benefits of logging noise
What are the benefits of logging noise?
  • Time history data logging provides very useful information for tackling excessive noise exposures
  • Focuses attention on noisiest periods during workday for correct usage of hearing protection or noise reduction at source
what other accessories are available
What other accessories are available?
  • CEL-110/2 acoustic calibrator
  • Used to verify the accuracy of the dosimeter
  • Use before and after each run to check for any drift in measurements
