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 specication 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 oers multi-drop

capability with cabling that includes power and communications.

Four dierent 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 congured for

gauge or absolute pressure types. With a recalibration time of 185

days and a high resolution of 8 signicant 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 oers 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.
