7. Maintenance and Recalibration

For contact details, please see Chapter 1 “General information” or the back page of the operating instructions.

7.1 Maintenance

The CPT6020 was designed for maintenance-free operation. User maintenance is not recommended. If you have questions not

covered by this manual, call 1-800-984-4200 (USA only), or 1-512-396-4200 for assistance, or send an email to techservices@

mensor.com.

7.1.1 Beyond the Warranty

Take advantage of Mensor’s expert product care. Mensor provides complete maintenance and calibration services, available for

a nominal fee. Our service staff is knowledgeable in the innermost details of all of our transducers. We maintain units that are in

operation in many different industries and in a variety of applications, and by users with a wide range of requirements. Returning

your transducer to Mensor for service benefits you in several ways:
• Our extensive knowledge of the transducer assures you that it will receive expert care.
• Repair or replacement of the CPT6020 transducers will be available up to 7 years after the production life cycle of the product,

pending external vendor parts or equivalent parts availability. The production life cycle is defined as the time from the product

series launch to the announcement of discontinuation (typically 8 to 10 years).

• All repairs should be performed by Mensor due to the complexity of performing these repairs.

7.2 Recalibration

The CPT6020 automatically calculates the pressure reading for all effects of temperature and non-linearity within the compensated

temperature range. The Process is referred to as dynamic compensation because each reading is adjusted before it is output.

Thus, a calibrated CPT6020 operated within its temperature band, and with proper zero and span adjustments, will provide

accurate pressure measurements.
The CPT6020 should have the calibration verified periodically to ensure stability. The recommended calibration interval for this

instrument is given in the Specifications section under “Calibration Interval” in Section

9.1.

.

7.2.1 Calibration Services by Mensor or WIKA worldwide

Mensor and WIKA worldwide have extensive experience and knowledge of Mensor products. Calibration of the transducers can be

performed at the addresses below or by competent internal or external labs using the procedures in this section.
