API Pressure Sensors-Transmitters
API pressure transmitters are built for reliable, real-time pressure measurement in industrial systems where accuracy is essential. These transmitters convert pressure into a stable electrical signal, giving operators precise data for pumps, compressors, hydraulics, pipelines, and process equipment. When API manufactures pressure transmitters, it focuses on making them tough and inexpensive, with the long service life, making them a sensible choice for many facilities.
These transmitters come in a wide array of options, with the ability to accommodate many pressure ranges and many sensing types, and they give good data with common industrial output signals. So in terms of versatility, these transmitters are a great choice, with API making them suitable for many applications and environments: from very light-duty OEM panel installations to outdoor, tough pressure monitoring systems in just about any kind of pipeline.
FAQs
What are API pressure transmitters used for?
API pressure transmitters measure real-time system pressure in pumps, hydraulics, compressors, pipelines, and industrial process equipment.
Are API pressure transmitters accurate and stable?
Yes, API transmitters provide stable, repeatable output signals with minimal drift, even in demanding or high-vibration environments.
What output signals do API pressure transmitters support?
Most API transmitters offer 4–20 mA, 0–5V, or 0–10V outputs for easy integration with PLCs, SCADA systems, and data-logging equipment.
Can API pressure transmitters handle corrosive or harsh media?
Many API models use stainless-steel wetted parts, welded diaphragms, and sealed electronics designed for chemicals, moisture, and extreme conditions.
Are API pressure transmitters easy to install?
Yes, they include standard process fittings, compact housings, and clear wiring terminals that simplify installation and retrofits.
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.
