INTRODUCTION
Thank you for choosing a Pressure Calibrator from Crystal Engineering Corporation.
The 30 Series are compact and rugged pressure calibrators designed to bring laboratory accuracy to outdoor field conditions. Every 30 Series Calibrator is
fully temperature compensated through extensive testing of all measured parameters while being exposed to environments of 0°C (32°F) to 50°C (122°F).
All 30 Series calibrators are intended for gauge pressure measurement. That is, they indicate the difference between applied pressure and ambient baromet-
ric pressure. The zero button also can be used as a tare function - extending the functionality of the calibrator for special applications.
They weigh less than a pound and advanced technology is employed throughout the product line. Sensors are constructed with stainless steel isolation
diaphragms and permanent oil fill. This means 30 Series products can be used with gases and liquids.
Long battery life is achieved with a low power, RISC (reduced instruction set) type micro-controller for computation of complex algorithms. A 24 bit analog to
digital converter provides internal resolution of 1 part in 16.7 million. Internal resolution always exceeds the displayed resolutions for all measurements. Full
accuracy is maintained even while the low battery icon is flashing.
The 30 Series is specified in percent of reading - instead of percent of scale. Why? Because one 30 Series calibrator could replace several conventional calibra-
tors by covering a wide range of pressure with high accuracy.
The Model 30 does not require any manual adjustments or trimming. All calibration is accomplished via an optically isolated communications port using a
USB physical interface. The optical isolation protects the Model 30 from electrical transients that may appear on the USB connector or cabling to a PC.
Your 30 Series can be customized through the use of our fr
tware. Your personal computer can disable, enable, or modify a variety of
features of your 30 Series.
•
Add or create new pressure units and/or disable unused pressure units
•
