APG Pressure Sensor-Transmitters
APG pressure transducers are made for accurate, stable pressure measurement in industrial environments where reliable performance is essential. They convert pressure into an electrical signal, which provides real-time data for pumps, hydraulic systems, pneumatics, water systems, and a variety of automated process equipment. Performance dependability is a key focus at APG, so their transducers tend to hold calibration well and deliver clean, noise-resistant output signals, even in electrically harsh environments.
Selection is one of the strengths of APG's pressure transducer product line. They have a really broad selection of sensing ranges, materials, and output formats to choose from. Whether you're measuring low-pressure air, high-pressure hydraulic systems, or the kind of system pressure you might find in a waterworks, APG has got you tailored and covered in terms of models and pricing. They also feature the kind of common industrial signal outputs—4 to 20 mA, a 0 to 5V output, or a 0 to 10V output—that make them easy to integrate with the sort of control and monitoring systems that tend to inhabit these industrial environments.
FAQs
What are APG pressure transducers used for?
APG pressure transducers measure system pressure in pumps, hydraulics, pneumatics, water treatment, and industrial automation equipment.
Are APG pressure transducers accurate and stable over time?
Yes, APG designs its transducers for long-term stability with minimal drift, providing reliable and repeatable pressure readings in demanding environments.
What output signals do APG pressure transducers support?
Most APG transducers offer 4–20 mA, 0–5V, 0–10V, or digital outputs compatible with PLCs, SCADA systems, and remote monitoring controllers.
Can APG pressure transducers handle corrosive or harsh media?
Many models include stainless-steel wetted parts and sealed housings that withstand chemicals, moisture, vibration, and extreme temperatures.
Are APG pressure transducers easy to install in existing systems?
Yes, they feature standard process connections, compact housings, and clear wiring terminals that simplify installation and system integration.
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.
