  • Page 10 131 Collecting Cone (02000-A-1642) The detection of a lighter than air gas is enhanced by the use of a Collecting Cone. The cone fits onto the Sensor accessory thread in place of the Filter Housing and retains the filter. The appropriate filter must be fitted. A nozzle on the cone permits gassing of the Sensor with the cone in position.
  • Page 11 133 Sample / Calibration Gas Flow Adaptor (1226A0411) A Flow Adaptor provides a facility to allow sampling of a closed system by means of two pipelines. The Flow Adaptor is fitted to the sensor accessory thread by a locking ring that enables the Flow Adaptor to be removed without disconnecting the pipeline.

  • Page 20: Calibration 20

    The calibration procedure should only be performed by qualified personnel. NOTe: Honeywell Analytics recommends that the maximum calibration interval be 6 months or in accordance with customer site procedures, whichever is sooner to assure the highest level of safety. Correct operation of each sensor/detector should be confirmed with test gas of known concentration before each use.
  • Page 21 Figure 11. MPD with Flow Adaptor NOTe The Gas Calibration menu is for both Zero and Span Calibration. 3. Connect the Flow Adaptor (using either gas pipe) to the regulated cylinder containing a known concentration of the target gas at approximately the sensor alarm point (e.g.
  • Page 22 72 Cross Calibration procedure for MPD-CB1 CAUTION Where the user calibrates any sensor using a different gas, responsibility for identifying and recording calibration rests with the user. Refer to local regulations where appropriate. When the MPD-CB1 Combustible LEL sensor is to be calibrated with a gas which is different to the gas or vapor to be detected, the following cross calibration procedure should be followed: NOTe...
  • Page 23 * Rating of * Rating of Gas to be Detected Calibration Table 2. Meter Settings 4. If a sensor is to be used to detect a gas other than that for which it was calibrated, the required correction factor may be obtained from Table 3. The meter reading should be multiplied by this number in order to obtain the true gas concentration.
