A pressure transducer is a device that generates a signal in response to a pressure measurement of a liquid or gas. In this context, pressure is defined as the force per unit area that is required to maintain a substance’s density, level, flow, speed, or altitude. The technology, configuration, application, performance specifications of pressure transducers can vary widely. 

A pressure transmitter is a device that creates a signal according to a pressure measurement of a liquid, vapor, or gas. Changes at the pressure source cause the diaphragm, or sensing element, to flex. The changes in the diaphragm are recorded as measurements. Measurements collected from the diaphragm response are translated into signals that travel on the transduction element to provide instructions to the control system. The control system sends instructions to maintain the preset density, level, flow, speed, or altitude. The technology, configuration, application, performance specifications of pressure transducers can vary widely.

Understanding the operational status of tank hatches and pump jacks at any given time is essential to maintain oil field productivity and regulatory compliance. SignalFire introduces a new multi-purpose wireless inclinometer that can monitor the status of tank hatch position or pump jack motion as part of a SignalFire Remote Sensing System. The patent-pending Tilt SCOUT uses a three-axis sensor that continually monitors angle to detect the orientation of a tank hatch or the motion of a pump jack. With feedback from the wireless sensor, workers can determine if a tank hatch is ajar and/or a pump jack is idle, and can take immediate corrective action to ensure proper and compliant operations.

Pressure instrument enclosures provide insulation, explosion-proof heating, heat shrink entry protection, and mounting systems for instruments such as probes, sample take off and conditioning cabinets, and transmitters. Pressure instrument enclosures are critical safety shields and barriers for volatile environments. Pressure Instrument Enclosures are comprehensive solutions for the range of vulnerabilities imposed on instruments by the operating conditions. High pressure testing enclosures protect pressure transmitters in extreme conditions. Pressure instruments must maintain validity and reliability, and enclosures are needed to provide protections against temperature, wind, vapors, gases, mechanical stress, and corrosion. The industrial protection products are designed to mitigate hazards and meet needs of specific operations and facilities. The functionality of multiple structures is united in a single unit, so installation, accountability, and servicing are streamlined. Furthermore, operational efficiency is optimized. 

Widely used in most industries, absolute pressure sensor applications provide specific measurements to meet both design and production needs. The steady growth of the global food packaging market size is one proof – where the main contributor is the consistent use of absolute pressure transmitters for their vacuum-sealed packaging.

Pressure measuring instruments are diverse, with each of them having different capabilities to suit your requirements in measuring pressure values under various conditions.

Interface measurements in desalters are often regarded as not being very critical, even though every drop of oil, to be refined, passes through the desalter. As refineries try to maximize their margins, so-called opportunity crudes are often used. These crude oils generally contain increased levels of sulphur, oil sands, bitumen, heavy oils and oils with high TAN. This can lead to problems with the proper operation of the desalter. In addition, refineries are increasingly confronted with stricter environmental regulations. The efficient level control of water/emulsions/oil layers in the desalter ensures that salts and minerals are effectively removed and that environmental requirements are met. Therefore, more and more operators are turning to radiometry as a highly reliable and accurate measurement solution for this application.

Most people are more familiar with – and often use – instruments for measuring pressure relative to the atmospheric pressure evident around us. However, some applications require absolute measurements, and this is where absolute pressure sensors come in.

DPharp digital sensor uses two single crystal silicon resonators vibrating at their natural frequencies. When pressure is applied, one of the resonators goes into tension, while the other goes into compression mode. The CPU directly counts the sensor output frequencies without any additional A/D conversion. Due to the excellent elastic properties of silicon material, the DPharp sensor exhibits greater linearity and repeatability, with no inherent hysteresis. Resonant sensor also provides a large output signal resulting in greater sensitivity and higher turndown.
