Description
The CPT6020 Precision Pressure Transducer is a self-contained
pressure sensing device that provides high accuracy pressure
measurements. This transducer incorporates a low hysteresis
silicon sensor with electronically compensated pressure linearity
over the compensated temperature range. The CPT6020
transducer is characterized over the full pressure and temperature
range to achieve 0.020% FS accuracy. This specication 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 accura-
cy pressure sensing is required. Examples are: ow calibrators,
humidity calibrators, pressure controllers, aerospace wind tunnel
calibration, automotive sensor testing, hydrology, oceanography,
in the aviation and space industries in general, or wherever high
accuracy pressure measurement and long-term calibration stability
are valued. It can also be used as a transfer standard or in pressure
calibration and testing areas of production facilities.
Precision Pressure Transducer, Model CPT6020
Functions
The model CPT6020 Precision Pressure Transducer has an
RS-232 or RS-485 interface. The RS-485 interface oers multi-drop
capability with cabling that includes power and communications.
Four dierent baud rates can be selected and the transducer can
be located up to 4,000 feet from the host. System designers appreciate these high accuracy remotely accessible transducers that
are not tied to a front panel. Each transducer can be congured for
gauge or absolute pressure types. With a recalibration time of 185
days and a high resolution of 8 signicant digits, the CPT6020 is
exible enough to be used in a wide variety of applications.
Design
The 316L SS construction and IP67 rating are an asset when utiliz-
ing in corrosive or wet environments. Its compact design oers an
advantage in miniaturization of product design in many OEM applications. The pressure connection and housing can be customized
to t your application. Standard ttings are easily changed using
the AN-4 or the Autoclave® F250C connection.
