Pressure Gauges (Traceable) Calibration

Analogue Pressure Gauge

A pressure gauge is a tool that provides the easiest, most direct way of measuring and displaying gas and liquid pressure. It’s one of the most commonly used pieces of equipment in refineries and electrical & industrial plants, with a wide range of applications in health care, energy production, and many other industries around the world.

Sometimes referred to as dial gauges, analog pressure gauges have a needle that directly responds to changes by pointing to numbers on a scale corresponding to the pressure sensed by the measuring element. The movement of the needle translates to variations in temperature or flow, which are easily noticed and monitored.

Digital Pressure Gauge

Digital pressure gauges are instruments that are designed to sense the pressure from a liquid or gas and provide a direct reading of that pressure value on a digital display, rather than requiring an operator to read a value from the position of a needle on a pressure scale as with analog pressure gauges. Digital pressure gauges make use of a transducer that converts the value of pressure into an electrical signal whose characteristics reflect the magnitude of the pressure reading.

Oxygen Pressure Gauge

Oxygen gas is used in a large number of applications throughout the world. The aviation, medical, and diving recreation industries use oxygen to enhance breathing while other industries use oxygen in applications such as welding. The gas is contained and transported in compressed gas cylinders and pressure gauges are used to monitor the pressures within those cylinders. The pressure gauges are typically mounted on regulators that control the output of the oxygen gas in the cylinder.

Nitrogen Pressure Gauge

The nitrogen gas uses of the product can be for a lot more things than you may realize. From food packaging to electronics production to mining, nitrogen gas is used in multiple applications every day. And these industries often rely on the nitrogen being delivered in nitrogen gas cylinders, The gas is contained and transported in compressed gas cylinders and pressure gauges are used to monitor the pressures within those cylinders. The pressure gauges are typically mounted on regulators that control the output of the nitrogen gas in the cylinder.

Magnehelic Gauge

Magnehelic gauges are low-pressure differential devices to measure very low pressures between two pressure sources. It works using a capsule bellows element and is suitable for use on clean dry gases. The twin entry onto the unit, high and low or up and downstream will allow the unit to measure the difference between both sources. They can also be used to measure positive, compound, or negative pressure. Custom dial markings are often used to allow easy reading.

The Magnehelic gauge uses an incredibly sensitive diaphragm that responds to changes in pressure. The Magnehelic gauge senses the differential in air pressure that is exerted on it. The pointer or dial that is connected to the diaphragm responds to the change in pressure between the two sides of the diaphragm giving the pressure reading. Due to the sensitivity of the diaphragm, the gauge must be level when taking a reading otherwise the diaphragm may sag which can lead to faulty readings.

Differential Gauge

A differential pressure gauge is an object that acts as an essential visual indicator of the difference in pressure between two pressure points of one pipe system. Most commonly, differential pressure gauges are used within industrial process systems, such as those installed in chemical plants, petrochemical plants, Power plants and refineries.

A differential pressure gauge measures the difference in pressure between two connections. Imagine an application where you have one tank at 100 psi and another at 95 psi. If you connect a differential pressure gauge between those two tanks, you will read 5 psi which is the difference between the two – needed information on one dial. Without a differential pressure gauge you’d need 2 gauges – one for each tank and you’d have to keep calculating the difference between the 2 gauge readings. This allows greater room for error and equipment damage.

Flow Meter

Also known as a flow sensor, a flow meter is a device designed for measuring nonlinear or linear flow rate. It measures the volumetric or mass flow rate of gases or liquids.

Flowmeters are tools used to monitor the amount of vapor, liquid, or gas passing through them. Some flowmeters are meant to measure the fluid amount flowing inside them after a period of time (100 liters per minute, for instance). Other flowmeters are meant to count the total amount in liters of fluid that has gone through them (such as 100 liters). Most flowmeters have three parts: the primary device, a transducer, and a transmitter. The work of the transducer is to sense the fluid passing the primary device. Raw signal from the transducer is then turned into usable data by the transmitter. A flowmeter may consist of one or many physical devices since these components are most of the time combined.

Manometer

A manometer is a scientific instrument used to measure gas pressures. Open manometers measure gas pressure relative to atmospheric pressure. A mercury or oil manometer measures gas pressure as the height of a fluid column of mercury or oil that the gas sample supports.

How this works is, a column of mercury (or oil) is open at one end to the atmosphere and exposed to the pressure to be measured at the other end. If atmospheric pressure is greater than the pressure on the other side of the fluid, air pressure pushes the column toward the other vapor. If the opposing vapor pressure is greater than atmospheric pressure, the column is pushed toward the side open to the air

Leak Tester (e.g. Pitot Static Tester)

A leak test is a procedure used to determine if an object, product, or system functions within a specified leak limit. A leak occurs when a gas or liquid flows through an object via an imperfection or manufacturing defect such as a hole, crack, or weak seal. These imperfections create high- and low-pressure zones within a product, forcing the gas or liquid to flow from the high-pressure area to the low-pressure area.

A good example of a leak tester in avionics is a pitot static tester. It is a system of pressure-sensitive instruments that is most often used in aviation to determine an aircraft's airspeed, Mach number, altitude, and altitude trend. A pitot-static system generally consists of a pitot tube, a static port, and pitot-static instruments.

Tyre Pressure Gauge (Digital | Analogue)

A tyre pressure gauge is used to measure the pressure of the tyres of a car, motorbike or any vehicle that uses inflated tyres. Simply using your eyes to estimate tyre pressure isn’t accurate and could lead to misleading results. Gauges offer accurate and reliable readings and come in both standard and digital formats.

PSI, pounds per square inch, is the measurement tyre pressure is recorded in. This number is used to interpret the pressure of the tyre. PSI is a commonly used scale for pressure measurement, however, alternative scales are also used and are sometimes in owners’ manuals, user guides and pressure gauges themselves. 1 Bar = 14.5 PSI 1kg/cm² = 14.2 PSI

Tyre Inflator (Digital | Analogue)

The tire inflator is a specific type of air compressor used for pumping up your car tires. The use of pressurized gas removes the need for strenuous pumping to fill your tires to the right pressure. Tire inflators can come in all shapes and sizes. Small handheld ones can easily fit in the boot of your car and are useful in an emergency. Larger tire inflators may not fit in your car but can reliably pump up your tires in record speed.

Tire inflators work through the process of positive displacement. Air pressure is steadily increased by a reciprocating piston which decreases the quantity of volume available. The piston, which is driven by a crankshaft, compresses air that flows into the compressor. A vacuum is then created above the piston when it moves down, allowing more air from the outside of the tire inflator to flow in. The piston then compresses the air which has flown in when it moves up again. This prevents more air from coming in and increases the pressure that’s already in the tire inflator. The compressed air moves into an air storage tank that opens up when the valve connected to it opens up.

Air Speed Indicator (Up to 250 Knots)

An air speed indicator (ASI) is a device for measuring the forward speed of the aircraft. The ASI uses the aircraft pitot-static system to compare pitot and static pressure and thus determine forward speed. Airspeed is usually measured (and indicated) in knots (nautical miles per hour) although other units of measurement are sometimes encountered. 

On older aircraft, airspeed is usually indicated to the pilot on a graduated scale over which a pointer moves. In modern aircraft, it is usually indicated on a speed tape which forms part of the Electronic Flight Instrument System display

Altimeter (Up to 20,000 Feet)

An altimeter is a device that measures altitude, the distance of a point above sea level. Altimeters are important navigation instruments for aircraft and spacecraft pilots who monitor their height above Earth’s surface. Skydivers and mountaineers also use altimeters to pinpoint their location in the sky or on the ground. The most common types of altimeters are barometric. They determine altitude by measuring air pressure. As altitude increases, air pressure decreases. This is because the density of air is lower (thinner) at high altitudes. It exerts less pressure on Earth below.
