Pressure Gauges
A pressure gauge is an analogue device for measuring pressure of liquids and gases. It does this with the use of a curved Bourdon tube, that straightens under pressure. This is linked to a pointer which displays on a graduated dial face and turns clockwise as the pressure rises. -
Vacuum & Absolute Gauges
Vacuum gauges are used between zero and atmospheric pressure, and minus -1 bar/-30 InHg. These have a Bourdon tube above -0.6 bar to -1 bar and a capsule measuring element from -10 mbar to -0.6 bar (-600 mbar). Absolute gauges are used when measured pressures are independent of natural fluctuations in atmospheric pressure. -
Diaphragm Gauges
Diaphragm gauges are a pressure measuring instrument with a barrier between the process medium and bourdon tube measuring system inside the gauge. This is to keep the process medium from blocking or corroding a standard bourdon tube gauge. -
Digital Pressure Gauges
Digital gauges are a precision instrument designed for reading pressure or vacuum where precise measurement is needed with high resolution. They are often used as a reference gauge that enable easy viewing with a large digital display. -
Magnehelic Gauges
Magnehelic gauges are low pressure differential devices to measure very low pressures between two pressure sources. It works using a capsule bellows element and are suitable for use on clean dry gases. The twin entry onto the unit, high and low or up and down stream will allow the unit to measure the difference between both sources. -
Differential Gauges
A differential gauge is a device designed to measure the difference in pressure between two pressure sources. This can be on gas, air or liquid applications. When installed, one port is connected on the low side and the other on the high side. This will show a pressure drop indicated on the display. -
High Accuracy Test Gauges
High accuracy test gauges are used as a test standard to calibrate other instruments. With an accuracy of ± 0.25% they are four times better than a standard class 1 gauge. A test gauge has many more divisions than a standard gauge and a fine knife edge pointer allowing you to get a more accurate reading. -
Sub Sea Gauges
Sub sea gauges can come in two different types. One type is to measure the pressure of the process independent of depth. This type has a solid drilled case built to withstand the external pressures surrounding the case without effecting the actual process pressure. The other type is not independent of depth so the external pressure surrounding the case is also taken in to account. -
Hand Pumps
Pneumatic and Hydraulic calibration hand pumps can be used to generate negative and positive pressure. Ideal for calibrating various instruments such as gauges, switches, transmitters and safety relief valves with small volume. With a small compact design these are ideal for engineers on-site who require precision pressure generation. -
Tank Contents Gauges
Tank gauges are designed for measuring the contents inside a tank. This can be done electronically or manually with an analogue display. The sensor is mounted at the bottom of the tank internally or externally. The hydrostatic pressure pushes down on the sensor which will be converted from a pressure into the appropriate contents or level reading. -
Grout Gauges
Grout gauges are to measure the pressure of fluids that would usually block a standard Bourdon tube pressure gauge. It was originally designed for tunneling and boring industry. Where diaphragm and chemical seals would have failed the grout gauge is a great replacement. It has an external diaphragm probe with no recess for the process medium to set. -
HVAC Gauges
HVAC gauge are industry specific for use in boiler rooms and air conditioning systems. They are low cost and show a good indication of pressure, temperature or even both. A combined pressure and temperature unit has also been designed to measure both all in one unit to save time and money on installation. -
Bespoke Gauges
Bespoke gauges can be any type of gauge we have specifically manufactured to suit certain applications. They could be analogue or digital with or without switching. Specially machined fittings or mouting brackets, custom ranges. -
Chart Recorders
Chart recorders are designed for measuring pressure, temperature or both over a period. The pressure side has a standard male or female pressure port like a standard Bourdon gauge. The temperature side would have a capillary going to an immersion which will fit directly into the process. -
Pressure Relief Valves
Pressure relief valves are mounted in a process line as a protective safety feature. It is designed to vent the pressure in a system to stop over pressure. They are commonly mounted by a threaded or flanged connection. Venting to atmosphere is common where inert gases are present, and the pressure is not too high. -
Block & Bleed / Manifolds
Block & Bleed manifolds are a type of isolation valve. They have multiple handles to isolate different parts of the system. They also have a bleed port so the system can be bled whist maintaining pressure in the gauge, or process. Many configurations and ports allow the pressure to be redirected or vented safely. -
Accessories
Pressure gauge accessories can be things like sealing washers to make installation safe. Isolation valves and manifolds so gauges can be removed safely, and systems bled. Gauge syphons are for shedding the temperature down to a suitable heat to avoid damaging the gauge and protecting the operator. -
Temperature Instrumentation
Temperature gauges are designed to measure the temperature of a process. They can be electronically, battery or mechanically driven with analogue or digital display. The sensors are often used in conjunction with a pocket or thermowell, this allows the gauge to be removed without the process escaping. -
Deadweight Testers
Deadweight testers are primary standard designed for generating high accuracy pressure. The pressure is generated using a screw pump and mass set in conjunction with a piston cylinder system. These are usually driven by a gas, air or hydraulic fluids such as oil or water.
