The high precision of these pressure transmitter of 0,01 %FS is available as an option (the standard Series RIB33 X has an accuracy of 0,05 %FS).
These Series are based on the stable, floating piezoresisitive transducer and the newly developed XEMICS micro-processor with integrated 16 bit A/D converter.
Temperature dependencies and non-linearities of the sensor are mathematically compensated.
With the READ30 software and the RIELS cable K-107, the calculated pressure can be displayed on a Laptop or PC.
The READ 30 software also allows the recording of pressure signals and the graphic display on the PC.
Up to 128 transmitters can be hooked together to a Bus-system.
Transmitter with Analog Output
Integrated in the XEMICS processor is a D/A converter of 16 bit for analog signal outputs of 4÷20 mA or 0÷10V.
The output rate is 400 Hz.
The accuracy is diminished by this converting process by 0,05 %FS.
The digital output is available on all transmitters with analog output.
Accuracy and Precision
“Accuracy” is an absolute term, “Precision” a relative term.
Dead weight testers are primary standards for pressure, where it is defined by the primary values of mass, length and time.
Highest class primary standards in national laboratories indicate the uncertainty of their pressure references with 70 to 90 ppM or close to 0,01%.
The dead weight testers, such as those used in our system for the calibration of pressure transmitters, indicate an uncertainty or accuracy of 0,025%.
Below these levels, RIELS use the expression “Precision” as the ability of a pressure transmitter to be at each pressure point within 0.01 %FS relative to these commercial standards.
The transmitter’s full-scale output can be set up to match any standard of your choice by correcting the gain with the PROG30 software.
Digital Interface
Added to the analog signal output pressure transmitters offer these digital interface with bus having the following options:
- Reading the values of pressure and temperature
- Zero offset and gain by the user
- Sizing of the ranges and units of the analog
- Composition of the configuration
- Reading information, as well as the number of series, range of pressure and temperature compensated range
- RS-485 two-wire half duplex with 9.600 baud and 115.200 baud
