Industrial Gauges

Industrial pressure gauges are built for the vibration, pulsation and rough handling found in plants, pump rooms and machinery. They give operators a dependable local reading of pressure in water, air, oil, steam and process lines.

Industrial Gauge Options

Stainless steel cases – corrosion resistance and durability
Liquid-filled gauges – dampen vibration and pulsation for steady readings
Brass and stainless internals – match media compatibility
Bottom and back connections – for line and panel mounting
Dial sizes from 2" to 6" – readable at a distance

Selecting a Gauge

Choose a range so normal operating pressure sits in the middle of the dial, generally about twice the operating pressure. Use a liquid-filled gauge on pumps and compressors, and add a snubber for pressure spikes. Confirm the connection size and accuracy grade.

Centro carries industrial pressure gauges for plant, process and equipment applications.

Process Gauges

Process pressure gauges are built for chemical, petrochemical, refining and power plant service. Heavy-duty cases, stainless wetted parts and high accuracy give dependable readings in demanding environments.

Process Gauge Features

Solid-front safety cases – operator protection
316 stainless steel internals – corrosive media
Liquid filling – vibration and pulsation damping
Accuracy to 0.5% – precise readings
4.5" and 6" dials – easy reading

Choosing a Process Gauge

Choose range, accuracy, connection and materials suited to the process. Add diaphragm seals for corrosive, viscous or high-temperature media.

Centro supplies process gauges and accessories for plant instrumentation.

Commercial Gauges

Commercial pressure gauges cover HVAC, plumbing, fire protection and general building services. They're economical, easy to read and available in many standard ranges.

Commercial Gauge Options

Dry and liquid-filled gauges – general service
Brass internals – water, air and oil
Common dial sizes – 2" to 4"
Bottom and back connections – line or panel mounting
Fire protection gauges – sprinkler system ratings

Choosing a Gauge

Select a range about twice normal operating pressure, and match connection size and dial type. Liquid-filled gauges handle vibration from pumps.

Centro supplies commercial gauges for HVAC, plumbing and building systems.

Pressure Gauges

Pressure gauges are instruments used to measure the pressure of fluids or gases in various industrial, commercial, and residential applications. They visually indicate the pressure levels, allowing operators to monitor and control processes effectively. Pressure gauges consist of a dial or digital display with a needle or numeric readout representing the pressure measurement in units such as PSI (pounds per square inch) or kPa (kilopascals). They typically feature a Bourdon tube, diaphragm, or other sensing elements that convert the applied pressure into a mechanical displacement, which is then displayed on the gauge. Pressure gauges are available in different types, including analog and digital, with varying accuracy levels and pressure ranges to suit specific application requirements. They are commonly used in oil and gas, manufacturing, HVAC, and automotive industries, where pressure monitoring is critical for operational safety, system performance, and quality control. Pressure gauges provide valuable feedback for adjusting process parameters, detecting leaks or anomalies, and ensuring the optimal functioning of equipment and systems.

Differential Pressure Gauges

Differential pressure gauges measure the difference between two pressure points. They show filter loading, flow through orifices, level in pressurized tanks and pressure drop across equipment.

DP Gauge Options

Diaphragm DP gauges – low differential ranges
Piston DP gauges – high line pressures
DP gauges with switches – alarms and control
Backflow test kits – backflow preventer testing
Accessories – manifolds and mounting kits

Choosing a DP Gauge

Specify differential range, maximum line pressure, wetted materials and connection. Use 3-valve manifolds to protect gauges during startup.

Centro supplies differential pressure gauges and accessories.

Differential Pressure Control

Differential pressure liquid control products are essential components used in various applications to monitor and control the pressure difference between two points in a liquid system. These products are designed to measure the pressure drop across filters, pumps, valves, or other flow control devices. They are crucial in maintaining proper flow rates, preventing system damage, and ensuring optimal performance. Differential pressure liquid control products typically consist of a differential pressure transmitter or sensor, a flow element (such as an orifice plate, venturi tube, or flow nozzle), and associated piping and instrumentation. The transmitter or sensor detects the pressure difference and converts it into a proportional electrical signal, which can be used for monitoring, control, or alarm. These control products find applications in oil and gas, chemical processing, water and wastewater treatment, and HVAC systems. They help optimize system efficiency, improve process control, and ensure liquid systems' safe and reliable operation by providing accurate and real-time differential pressure measurements.
