M a i n t e n a n c e
Typical maintenance for the sensor consists of checking the wiring to make sure it is not
corroded or frayed, checking the atmospheric vent tube to make sure it is intact and leak-free,
and checking or setting the field calibration offset.
Maintenance should be performed at least every 6 months, in order to insure that the sensor
meets the accuracy specifications.
The offset can be checked by venting the sensor to the atmosphere and taking a reading from
the sensor.
If the sensor has been subjected to more than its maximum pressure, the offset of the unit
should be checked as described above.

clogged nose piece or dirty diaphragm
Either of these conditions could result in erroneous readings from your transducer.
WARNING: NEVER
attempt to clean your transducer’s nose piece or diaphragm with any
object. This will dent the sensor diaphragm and cause permanent damage to the
transducer.
Your transducer may be cleaned in accordance with the procedures listed in step 4, below.

materials required:
Materials required:
Plastic bowls 8-12 inches in diameter and 4-6 inches deep
Supply of clean, lint-free cleaning rags
32 ounce bottle of “The Works-Tub and Shower Cleaner” (a mild detergent)
manufactured by Lime-O-Sol Company in Ashley, IN 46705 and available locally
through Wal-Mart, K-Mart, Target, and Ace Hardware stores at $2 to $4 per
bottle
Preparation:
Prior to cleaning your pressure transducer, ensure that all procedures have been
followed in the proper cleaning of the cable and transducer to remove any hazardous materials.
The vent filter (or bellows) must be properly attached. The cable should be coiled to ensure
ease of handling and it must be protected against the possibility of accidental abrasion and/or
penetration of the cable jacket by sharp objects. A lead length of 1 to 1 ½ feet of cable from the
transducer should be allowed to facilitate handling during cleaning. The protective covering (or
similar protective device) that is shipped with each transducer should be attached to the
transducer at all times. It should only be removed prior to installation or cleaning. Your work
