Fluke 721 Ex precision Pressure Calibrator Basics, Features and Accessories

Fluke 721Ex Precision Pressure Calibrator is an ideal tool for gas custody transfer calibration because of its dual isolated pressure sensor. It measures simultaneously static and differential pressure with a single tool. For safe operations in a hazardous environment with potentially explosive atmosphere, Fluke 721 Ex is safely rated with IECEx and Atex Ex ia IIB T3 Gb (Zone 1). It allows professional Technicians to perform gas transfer study without a hot work permit and also eliminates the need of working in specific area conditions during calibration. During custody transfer, professionals calibrate all the temperature and pressure transmitters involved in the flow of oil and gas as well as the pressure in the pipelines. In previous articles, we explain 6270 a calibrator, Fluke 754 calibrator, Fluke 726 calibrator measurements etc. In this article, we are going to explain Fluke 721 Ex precision pressure calibrator  features, accessories etc in detail.

Fluke 721 x Pressure calibrator Basics:

This is one of the most demandable precision pressure calibrator used nowadays. First of all guys, it is important to know some basic terminologies of Fluke 721 ex pressure calibrator.So here we are going to explain you some basic terms about calibrator. Have a look at it.

Calibrator

For adjusting an accuracy of an instrument, Calibrator is the well known and used equipment. Each & every industrial equipment is calibrated first to ensure that it performs well and give results as expected by the user. The most sophisticated industrial equipment will not be very useful unless it is calibrated. In Research & development departments, you have to ensure that you are delivering predictable & accurate results which meet quality standards. Calibrators vary in form and function depending on the instruments with which they are designed to work.

Calibration

Calibration is the process of adjusting a device to meet manufacturer’s specifications. For assuring the end user regarding the product conformance with the specification, calibration sometimes issue data includes report or certificate of calibration and also standardised by ISO 9001 Standards. A company may gain acceptance among different suppliers & buyers by following these standards to ensure its products & services.

  14. Sensor 2 resolution: 0.01 psi,0.001 bar
  15. The large backlit graphic display basically displays three inputs simultaneously.
  16. Switch test on both pressures inputs.
  17. The optional Fluke temperature probe i.e. 720RTD is also available.
  18. Sensor 1 range: – 14psi to +16 psi, -0.97 bar to 1.1 bar
  19. Sensor 2 range: – 12psi to +300 psi, -0.83 bar to 20 bar

Calibration of flow computer:

For proper calibrations, each flow computer designer provides a software application which runs on a PC. For making a communication between PC & flow computer, a serial port or USB port is used. In this way, the software installed on the PC instructs the user to connect correct signals to flow computer and transfer information to the flow computer so that the pressure calibrator calibration errors can be corrected.

Accessories of Fluke 721 Ex precision Pressure Calibrator 

When we go to the market to purchase something, sometimes due to lack of knowledge, we don’t know what accessories we got inside the box. Fluke 721 Ex Calibrator kit includes the following :

  1. User Manual.
  2. Test leads.
  3. Dual sensor Pressure Calibrator.
