The CPT6020 precision pressure sensor is a pressure sensing instrument that provides high-accuracy pressure measurements. This sensor 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).

The model CPT6020 precision pressure sensor is for OEM instruments that require high-accuracy pressure sensor. 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

Or 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.

The model CPT6020 has an RS-232 or RS-485 interface. The RS-485 interface offers multi-drop capability and simple cabling that includes power and communications. Four different baud rates can be selected and the sensor can be located up to 1,220 m [4,000 ft] from the host. System designers appreciate these high accuracy remotely accessible sensors that are not tied to a panel.

The sensor can be configured for gauge or absolute pressure types. With a calibration interval of 185 days and a high resolution of 8 significant digits, the CPT6020 is flexible enough to be used in a wide variety of applications.
