Oxygen DP Measurement
There are different pressure types of pressure measurement based on the principle of operation: gauge pressure, absolute pressure, and differential pressure.
• Gauge Pressure
It takes the atmospheric pressure as the reference point. Since the atmospheric pressure may vary according to different locations, a gauge pressure sensor is needed to ensure accurate pressure measurement. Generally, a gauge pressure sensor has a vented tube connecting atmosphere pressure as a reference point to measure the media pressure.
• Absolute Pressure
It takes the perfect vacuum as the reference point. Absolute pressure measurement is commonly used in vacuum systems and applications where zero pressure is crucial.
A formula shows the difference between gauge pressure and absolute pressure: Absolute pressure = gauge pressure + atmospheric pressure
The pressure difference between two points or systems is known as differential pressure. A gauge is a specific differential pressure in that one pressure is always atmospheric.
The pressure transmitter is also known as a pressure transducer in some areas. It is a device used to measure and transmit a signal proportional to the pressure applied. The structure of a pressure transmitter can vary depending on the application, but typically includes the following main components:
• Sensing Element
This is the essential component for pressure measuring that converts the applied pressure into an electrical signal.
• Circuit Board Chip
Circuit board chips are divided into analog chips and signal conditioning chips. This component amplifies or processes the electrical signal into a transmittable, unified standard signal. It can be a 4-20 mA current loop, voltage output and digital outputs.
• Housing
The sensing element and circuit board chip are enclosed in a housing to protect them from environmental factors like vibration, shock, and moisture. Housing with optional materials such as stainless steel 316L, SS 304, Hastelloy C, Tantalum, etc., according to the different working environments.
• Electrical Connection
These connectors link the transmitter to the power supply and other instrumentation in the control system. B1 4-pin Plug Connector, B2 Cable Connection, and other types are available. The choice of electrical connection depends on factors such as the current carrying capacity, voltage level, application requirements, and industry standards.
• Process Connection
It involves the physical connection between the pressure transmitter and the process piping or equipment. There are several types of process connections commonly used in industrial applications, including thread connection, flanged connection, clamp connection, etc.
The choice of process connection depends on factors such as the process fluid, pressure, temperature, pipe size, and compatibility with the instrument. It is important to select the appropriate process connection to ensure accurate measurement, reliable operation, and safety.
According to the characteristics of the output signal, the output mode of the pressure transmitter has analog output and digital output.
• Analog Pressure Transmitter
Common analog outputs include 4-20mA, 0-5V/10V DC, 0.5-4.5V DC, etc. In practical applications, users can more conveniently collect, process and restore analog signals.
In maintaining the output signal's consistency, the analog pressure transmitter is more convenient to replace and maintain on-site. Compared with digital output products, the system response speed of analog output products is faster. Therefore, in special working conditions with higher requirements on frequency response, analog output pressure transducers are more suitable.
• Digital Pressure Transmitter
Common digital outputs include RS485, I²C, HART, etc. Its system cost is lower when solving multi-point measurement applications. Compared with analog output products, the digital pressure transmitter is convenient for networking and conducive to online adjustment.
Among many digital products, RS485-Modbus is one of the most widely selected. The product has strong anti-interference ability and long transmission distance. I²C hardware is low-cost, fast, and has high data volume.
MicroSensor provides digital and analog output signal pressure transducers depending on your system compatibility, communication requirements, noise immunity, and the level of accuracy needed for the application.
