Precision pressure sensor

Description 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). Application 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.Functions 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.
