Fluke 721Ex-3603 Precision Pressure Calibrator
The Fluke 721Ex-3603 Precision Pressure Calibrator is a sophisticated instrument designed to meet the rigorous demands of gas custody transfer applications, particularly in environments that are potentially explosive. This device is part of the Fluke 721Ex series, which is known for its reliability and precision in pressure calibration tasks.
Design and Features
The Fluke 721Ex-3603 is equipped with dual isolated pressure sensors, crafted from stainless steel for durability and accuracy. These sensors enable the device to perform simultaneous static and differential pressure measurements, a critical capability in gas custody transfer applications. The calibrator's design is intrinsically safe, certified under IECEx and Atex Ex ia IIB T3 Gb for Zone 1, making it suitable for use in hazardous environments where flammable gases or vapors may be present.
The device offers a pressure range of 36 psig to 300 psig for the high-pressure sensor, with a resolution of 0.001/0.01 psi and an accuracy of +/-0.025%. This level of precision ensures reliable measurements critical for the gas custody transfer process. The Fluke 721Ex-3603 also features a Pt100 RTD input for temperature measurement, enhancing its versatility and utility in various calibration scenarios.
Connectivity and Usability
A significant advantage of the Fluke 721Ex-3603 is its large backlit graphic display, which can show up to three inputs simultaneously. This feature allows for easy monitoring and analysis of measurement data in real-time. The device is designed for user convenience, with the ability to store five instrument setups for quick recall, streamlining the calibration process.
The calibrator can measure 4 to 20 mA signals and provides an internal 24V loop power supply to power transmitters under test. This functionality is particularly useful for calibrating pressure transmitters in the field or on the bench.
Construction and Portability
The Fluke 721Ex-3603 is built to withstand the rigors of industrial environments. It features a robust construction and comes with a soft case, four AA batteries, a manual, a traceable calibration certificate, and test leads. The device's compact dimensions and lightweight design make it easily portable, allowing for flexibility in various calibration tasks.
In summary, the Fluke 721Ex-3603 Precision Pressure Calibrator is a highly reliable and accurate tool for gas custody transfer applications, especially in potentially explosive atmospheres. Its dual sensor capability, precision measurements, and intrinsically safe design make it an essential instrument for professionals in the field.
