Analogue pressure transducer

The CPT6030 analogue pressure transducer is a self-contained pressure sensing instrument that provides high-accuracy pressure measurements with a 2-wire, 4 ... 20 mA output. This transducer incorporates a low-hysteresis silicon sensor with electronically compensated pressure linearity over the compensated temperature range.
The CPT6030 is characterised over the full pressure and compensated temperature range to achieve 0.025 % FS accuracy. The metrological grade accuracy of 0.025 % FS includes linearity, hysteresis, repeatability drift and reference uncertainty over the temperature range. Also featured is an output which is updated at a rate of 21 readings per second (47 ms).

Application
The analogue pressure transducer can be used to verify and adjust industrial and process pressure transmitters as a compact calibration solution.
The CPT6030 can also be used for OEM applications.

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 CPT6030 is a smart pressure transducer with calibration and compensation data stored on-board the sensor at all times. It can be configured with a digital interface using RS-232 to set and adjust zero and span.
Each transducer can be configured for gauge, absolute or bidirectional pressure types with pressure ranges as low as 25 mbar ... 1,001 bar [10 inH₂O ... 15,015 psi] and a calibration interval of 365 days. This analogue pressure sensor accepts a voltage supply from DC 15 ... 28 V making it flexible enough to be used in a wide variety of applications.

Design
The 316L stainless steel construction and IP67 rating are an asset when utilising the transducer in corrosive or wet environments. Its compact design offers an advantage in miniaturisation of product design in many OEM applications. The pressure connection and case can be specified individually and according to customer requirements. Standard fittings are easily changed using the SAE J514/JIC connection or the Autoclave^® F250C connection.
