What are various Pressure calibrators and how to use them?

1. What are pressure calibrators? Pressure calibrators are exact pressure measuring instruments that can verify and calibrate the pressure value of another pressure measuring device. Pressure calibrators include a deadweight tester, multifunction calibrator, or test gauge. These pressure calibrators provide a faster and easier way to calibrate and maintain pressure-measuring devices with high accuracy in …

Overview of pressure measurement

Pressure Transmitters Pressure is one of the most common properties to detect. We frequently sense differential pressure to determine fluid flow, liquid level, and equipment performance. Pressure transmitters can be designed to measure absolute pressure or gauge pressure. All sensors will sense pressure above atmospheric. Most, but not all, will measure pressure below atmospheric (a partial …

Introduction McCLEOD GAUGE is generally used as a primary standard for the measurement of high vacuum (low pressure) and is simple to use. It was invented in 1874 by Herbert McCleod. Principle McLeod gauges operate by taking in a sample volume of gas from a vacuum chamber, and then compressing it by tilting, and infilling …

What are capillary lines? and what is it used for?

Introduction Capillary lines are utilized when instruments need to be removed from direct contact with the installation point due to elevated process temperature, pressure spikes or design specifications. Added between the measuring instrument and diaphragm seal, it protects from damage and/or accuracy degradation with slow heat transfer rate and dead-ended process fluid providing further protection When a gauge …

Working of Pneumatic differential pressure transmitters

Introduction Pneumatic differential pressure transmitters are designed for measuring the pressure, differential pressure or level of liquids, steam, gas or air. The measured value is transmitted as 3 to 15 psi pneumatic signal to remotely mounted receiving equipment such as recorders, indicators or controllers or combinations of these items. Principle of operation The system is depicted …
