Model 3430 Plus & 3440 Plus
Surface Moisture-Density Gauge
The Model 3440 Plus Surface Moisture Density Gauge can
be equipped with an optional global positioning system (GPS)
receiver. If such a gauge is moved a long distance between uses,
the GPS system must be allowed to initialize. In some instances,
initialization may take as long as 30 to 45 minutes from the time
the gauge is powered on with the GPS enabled. Note also that
the gauge must be positioned such that the GPS receiver can
receive signals from the GPS satellites (see Appendix I for more
information). If the GPS does not initialize within 45 minutes,
contact your Troxler representative.

  • Page 126: Types Of Radiation

    TYPES OF RADIATION The radioactive sources in the gauge produce four types of radiation: Alpha particles Beta particles Gamma rays (photons) Neutrons The alpha and beta particles are stopped by the source capsule. Therefore, they present no external hazard to personnel. Only the gamma and neutron radiation from sealed sources contribute to any occupational radiation exposure.

  • Page 128: Limiting Exposure

    LIMITING EXPOSURE Under average conditions, an individual working with the gauge will receive less than 200 millirem per year. A basic principle of radiation protection is that radiation exposure should be kept as far below the limits as is reasonably achievable. This is known as the ALARA (as low as reasonable achievable) principle.

  • Page 131: Source Rod Inspection

    SOURCE ROD INSPECTION To ensure the integrity of the source rod, Troxler recommends that a qualified Troxler service person inspect the gauge and the source rod at least once every five years. This inspection includes checking for excessive wear, corrosion, or damage that could affect the safety of gauge operation.

  • Page 132: Daily Inspection

    DAILY INSPECTION The gauge should be inspected daily before use to ensure proper operation of all safety features as follows: ✓ The source rod opening in the bottom of the gauge is equipped with a spring-loaded tungsten sliding block that shuts when the source rod is in the SAFE (shielded) position.

  • Page 133: Cleaning The Tungsten Block

    If the sliding block still does not close properly, immediately contact the nearest Troxler Service Center. For a list of Troxler and authorized Troxler service centers, refer to page iii of this manual or visit the Troxler website at www.troxlerlabs.com/SERVICES/services.shtml.
  • Page 134 ✓ With the source rod in the SAFE (shielded) position, place t h e gauge on its side. ✓ Clean the heads of the four corner screws that hold the bottom plate to the gauge base (Figure A–3). Using a Phillips screwdriver, remove the four screws in the corner of the plate and remove the plate.

  • Page 202: Gps Accuracy

    GPS ACCURACY As described earlier, the Model 3440 Plus gauge can be equipped with an optional GPS receiver that determines the location (latitude and longitude) of the gauge. This information is stored with each gauge measurement. The GPS receiver used in the Model 3440 Plus has Wide Area Augmentation System (WAAS) capabilities, which provides accuracy to within 3 m (10 ft).
  • Page 203 Note also that the gauge must be positioned such that the GPS receiver can receive signals from the GPS satellites as described above. If the GPS does not initialize within 45 minutes, contact your Troxler representative. Model 3430 Plus & 3440 Plus...
