What is a Pressure Gauge?
Pressure gauges instruments measure the pressure of liquid or gaseous materials by calculating the force they would exert at a state of rest. The gauge displays the difference between the pressure in the measured area and that of the surroundings, called the gauge pressure.
The absolute or total pressure of the area will be the sum of the pressure difference measured by the gauge and the atmospheric pressure. Units for measuring pressure include:
- Pascal (Pa)- Newtons per square meter
- PSI – Pound/pound-force per square inch
- Newtons per square centimeter
Types of Pressure Gauges
There are a variety of methods for measuring force, which means there are numerous types of pressure gauges. The classification can be based on the principles used for measuring pressure, the method of operation (mechanical or electrical), and the type of output (digital or analog).
Commercial Pressure Gauges are suitable for a wide range of general commercial and utility applications. They are commonly utilized in refrigeration, HVAC systems, and food and beverage processes. Due to their versatility, commercial pressure gauges are used by various end users and original equipment manufacturer (OEM) appliances.
Industrial Pressure Gauges, constructed from stainless steel, monitor the pressure of mediums that don’t cause obstructions in the system, such as oil, gas, and other fuels. These gauges find widespread use in industries manufacturing or processing chemicals, mobile hydraulics, alternative fuels, and other petrochemicals.
Process Pressure Gauges withstand pressure systems exposed to environmental extremes and stresses caused by vibrations, spikes in pressure, pulsation, or corrosion. They are common in industries dealing with both gas and liquid petrochemicals.
Low Pressure Gauges and systems increase operational stability in systems that contain gaseous or liquid materials in corrosive environments. These gauges are suitable for applications such as plant construction, cleanrooms, pneumatic systems, chemicals, and petrochemicals.
Seal Gauges are purpose-built gauges that combine pressure gauges with diaphragm seal isolators to eliminate leaks in the system through the gauges. Therefore, Seal Gauges are ideal for sanitary, pharmaceutical, chemical, and petrochemical industries.
High Precision Test Gauges are essential tools for testing and calibration laboratories seeking highly accurate results and measurements. Typically, you would use these gauges in pressure monitoring panels and applications where the mediums will not cause obstructions or damage copper alloy parts.
Duplex Pressure Gauges and Differential Gauges are used in applications where two applied pressures need to be measured – static process pressure and high/low pressure. They are suitable for harsh and corrosive environments like HVAC, refrigeration, cryogenic gases, and air handling industries.
Absolute Pressure Gauges take measurements independent of environmental conditions. For example, applications often use them to measure the vapor pressure of liquids and to monitor condensation pressures.
Why Pressure Gauge Calibration is Critical
Pressure gauges are everywhere in industrial and laboratory settings, making them indispensable for countless processes. Consequently, the prevalence of pressure gauges often leads to complacency, causing people to overlook or postpone calibration. However, these instruments’ accuracy is paramount for operational efficiency and safety.
Safety is a primary concern. Employees rely on pressure readings to identify potential hazards. Inaccurate gauges can mask dangerous conditions, putting personnel at risk.
Quality and productivity are also at stake. Precise pressure measurements are essential for maintaining product quality and consistency. Inaccurate gauges can lead to costly errors, rework, and production delays.
Regulatory compliance is another factor. Many industries have stringent requirements for equipment calibration. Failure to comply can result in hefty fines and reputational damage. Trescal’s 780+ accreditations in 28 metrological and test domains guarantee quality and reliability.
Regular pressure gauge calibration is not an optional maintenance task; it is a crucial component of overall operational excellence.
