WARNING! Physical injuries and damage to property and the environment caused by hazardous media
Upon contact with hazardous media (e.g. oxygen, acetylene, flammable or toxic substances), harmful media (e.g. corrosive, toxic, carcinogenic, radioactive), and also with refrigeration plants and compressors, there is a danger of physical injuries and damage to property and the environment. Should a failure occur, aggressive media with extremely high temperature and under high pressure or vacuum may be present at the instrument.
For these media, in addition to all standard regulations, the appropriate existing codes or regulations must also be followed.
Wear the requisite protective equipment (see Chapter 3.6 “Personal Protective Equipment”).
CAUTION Damage to the Instrument
When working on open electrical circuits (printed circuit boards) there is a risk of damaging sensitive electronic components through electrostatic discharge.
The correct use of grounded working surfaces and personal armbands is required.
5.1 Mounting
The transducer may be mounted via its process connection or with any ring clamps along its body. Having the sensor oriented in a position other than vertical (with the port down) might cause a slight zero shift than can be removed by re-zeroing the transducer.

5.1.1 Pressure Connections

The CPT6020 has a JIC4 type female connection. When installing a mating connector, do not torque the connector with more than
13 ft-lbs or galling might occur. The transducer is supplied with a crush washer that can be used to further eliminate leaks.

5.1.2 Safety Relief Valves

Mensor recommends that an appropriately sized relief valve be placed in line with the pressure port of the transducer.

5.1.3 Pressure Media

A media comparable with the wetted parts of the transducer must be used.

Operation

6. Operation
6.1 General Operation
The CPT6020 transducer can be ordered with either an RS-232 or RS-485 full duplex output. The communications protocol is defaulted to 57600,N,8,1. The baud rate can be changed via remote commands. Connector pinouts and RS-232 and RS 485 cable connections are shown in Figure 5.1.2. The transducer has multiple command sets with which it can communicate with the host. These are set through the CMD_SET command.

6.1.1 Command and Query Format

Commands must be sent in ASCII format and terminated with a carriage return (<CR>) followed by a linefeed (<LF>). Commands are not case sensitive. Query strings are terminated with a “?” prior to the termination character(s). If the transducer is put in a burst output mode, the output of the transducer is in a binary output mode. The host communications program must synchronize with the output of the transducer. The transducer’s output to a pressure value query is programmable depending on what the user wants in the output string.
6.1.1.1 RS-485 Command and Query Format
On RS-485 versions of the CPT6020, the commands must be preceded by a “#”, an address or a “*”, and a space. In RS-485 the ADDRESS command sets the address in ranges from “0” to “9” and “A” to “Z”. The global address character is the “*”. When data is required for a command, a space (only) should delimit command and data fields.
6.1.1.2 RS-232 Command and Query Format
On RS-232 versions of the CPT6020, the “#” or address character is not necessary to precede the command for the Sensor command set. But, the Mensor Legacy command set still requires a proceeding “#” and address character. With the default sensor command set in RS-232, the start character and address character are not required.
6.1.1.3 Command Error Detection and Debugging
The CPT6020 has built in responses to correct and incorrect data. The responses can be used to help debug the software. In the Sensor command set, the device will return “Ready” in response to a valid data command. If the device is in the Mensor Legacy command set, an “R” will be returned in response to valid data. If the data is determined to be invalid, the Sensor command set will return “Invalid Data”. The Mensor Legacy command set will still return an “R” character when invalid data is sent. This is a limitation of the Mensor Legacy command set. The Sensor command set will return “Unknown command” if the command is not found, while the Mensor Legacy command set will ignore it and not respond. This paragraph is summarized below in the following table:
Mensor Legacy Command Set
Case Return Value
Valid data command “R”
Invalid data command “R”
Invalid command Nothing
Sensor Default Command Set
Case Return Value
Valid data command “Ready”
Invalid data command “Invalid Data”
Invalid command “Unknown Command”
Query Customer password protected command “User Password Needed”
Table 7.1.1 Command set returns for given cases

Table 6.1.2 – Sensor Command Set
Password Protection
In the Sensor Command Set, data that affects calibration is protected by a user settable 4 character password (designated as “Password Protected”). The default password is “0000”. This is changed using the PWD_CHANGE command. It should be changed once the user receives the device. The factory password will override the user’s password in the case that the user loses their password.
Filter & Window
The filter is a percentage of the previous reading averaged with the current reading - as long as the current reading is within the window of the previous reading. The window is set as a %FS of the transducer’s range. If the current reading is outside of the window from the previous reading, the filter is unused and the current reading is displayed without manipulation. This scheme allows the user to tune the transducer’s response as they like. It also allows the transducer to respond to rapid pressure changes without having to change the filter. The default values are 0.01% FS for the window and a filter of 90%.

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.

Maintenance and Recalibration

7.2.2 Environment

For maximum accuracy, allow the CPT6020 to warm up a minimum of 15 minutes in ambient temperature within the compensated range prior to a calibration. In addition, the instrument should be at rest on a stable platform that is free of excessive vibration, shock and with minimal temperature change.

7.2.3 Pressure Standards

Mensor recommends the use of appropriately accurate primary pressure standards when calibrating this instrument. Such standards should be sufficient so that when the techniques of the ISO Guide to the Expression of Uncertainty in Measurement (GUM) are applied, the instrument meets its accuracy statements as required by ISO/IEC 17025:2005, or other applicable standards.

7.2.4 Media

The recommended calibration medium is dry nitrogen or clean dry instrument air. For ranges above 5 psi any liquid media compatible with 316L SS is acceptable. A reference height variation between the standard and the CPT6020 can cause errors. A calculation should be made to compensate for this difference.

Figure 7.2.5 - Calibration Setup
When calibrating absolute transducers and approaching very low absolute pressures, you must use a needle valve or controlled leak to maintain a small pressure (600 mTorr, 80 Pa recommended) throughout the system. If you try to run calibration points below that pressure, the system will have significant pressure gradients in it unless left to stabilize for an extended period of time.
