The model CPT6020 precision pressure transducer is a self-contained pressure sensing instrument that provides high-accuracy pressure measurements. This transducer used a low-hysteresis silicon sensor with electronically compensated pressure linearity over the compensated temperature range.
The CPT6020 is characterised over the full pressure and temperature range to achieve 0.020 % FS accuracy. This specification includes linearity, hysteresis, repeatability and temperature errors. Also featured is an output which is updated at a rate of 50 readings per second (20 ms).
Application
The CPT6020 is used in OEM applications where a high-accuracy pressure sensing is required.
Examples are:
- Flow calibrators, humidity calibrators, pressure controllers
- For aerospace wind tunnel calibration and also for the automotive sensor testing
- In the aviation and space industries in general, hydrology and oceanography
Also for applications where high-accuracy pressure measurements and long-term calibration stability are required. It can also be used as a transfer standard or in pressure calibration and testing areas of production facilities.
Functions
The model CPT6020 has a USB, RS-232 or RS-485 interface. The RS-485 interface offers multi-drop capability and cabling that includes power and communications. Five different baud rates can be selected and the transducer can be located up to 1,220 m [4,000 ft] from the host.
Each transducer can be configured for gauge or absolute pressure types. With a calibration interval of 180 days and a high resolution of 8 significant digits, the CPT6020 is flexible enough to be used in a wide variety of applications.
