APG Pressure Gauges
APG pressure gauges provide reliable pressure measurements in industrial applications where precision and dependability are essential. The gauges, like their counterparts in the industrial world, are built to be tough and trustworthy. Operators can use them in water treatment, oil and gas, manufacturing, and many other industrial applications to monitor system pressure, protect equipment, and maintain peace of mind over safety concerns.
Rigorous testing of the APG pressure gauges ensures they won't fail in any condition likely to be experienced in the field. All of the gauges feature high-quality Bourdon tubes (the most common internal mechanism for pressure gauges), welded or sealed construction, and housings made of corrosion-resistant materials, enabling them to withstand moisture, temperature swings, and exposure to aggressive fluids.
APG also stresses unmistakable readability and uncomplicated installation. Their pressure gauges are made with distinct markings, wide dials, and straightforward scales, which allows a technician to view the system pressure and interpret it accurately with just a glance. The ease of installation—thanks to typical process connections and common fittings—means you can mount the gauges on either new or existing equipment.
FAQs
What are APG pressure gauges used for?
APG pressure gauges measure system pressure in pumps, pipelines, tanks, compressors, hydraulics, and other industrial process equipment.
What types of pressure gauges does APG offer?
APG manufactures stainless-steel gauges, glycerin-filled gauges, dry mechanical gauges, and digital pressure gauges.
What are glycerin-filled APG gauges for?
They help dampen vibration and pressure spikes, improving readability and extending gauge life in systems with pulsation.
Do APG pressure gauges work with hydraulic or pneumatic systems?
Yes, APG gauges are widely used on hydraulic systems, air compressors, pumps, and general pneumatic equipment.
Does APG offer digital pressure gauges?
Yes, APG digital gauges provide high-resolution readings and advanced features like data capture, alarms, and programmable settings.
Instrumentation: Elements & Transmitters
2 pieces of hardware used in modern day instrumentation: measuring elements and transmitters.
Measuring Elements
Measuring elements are the part of the device that performs the measurement. For example, the measuring element of a pressure transducer is the part that is actually lowered into a tank that will take a pressure measurement. The measuring element of a flow meter is the part that actually measures the flow and an RTD or thermocouple takes the temperature measurement.
Transmitters
Transmitters collect information from measuring elements and sends the information to where it is needed. The transmitter interfaces with the measuring element and interprets the information. It then sends that information to a PLC, RTU or some other type of control unit. In many cases, the transmitter has the ability to communicate the information via multiple communication protocols. This may be necessary when the measuring element does not send the same type of signal that is needed by the controller. For example, it may be necessary to convert a temperature reading from a thermocouple to a 420 milliamp signal that can be received by a local PLC.
