Breeze Differential Pressure Transmitter
Differential pressure transmitters are transmitters that measure the difference in pressure across the transmitter. Output standard signals (such as 4~20mA, 0~5V).Differential pressure transmitters are mainly used to measure differential pressure, pressure and negative pressure of liquids, gases and steam. It is also possible to measure liquid levels in open or pressurized vessels. Equipped with a throttling device, it can measure the flow of liquid, gas or steam, and convert the measured parameters into a 4-20mA DC signal output. Density can also be measured with a differential pressure transmitter.

Types Of Pressure Differential Pressure Transmitter
Capacitive Differential Pressure Transmitter
This transmitter uses a capacitive sensor. The process pressure passes through isolating diaphragms on both sides or on one side. Then the filling fluid acts on the tensioned measuring diaphragm in the delta element (ie, the sensitive element). The measuring diaphragm and the capacitive plates on the insulators on both sides each form a capacitor.
Diffused silicon differential pressure transmitter
The diffused silicon differential pressure transmitter uses diffused silicon sensing technology. By applying the measured pressure to the silicon chips on both sides respectively, the tiny resistance changes inside the silicon chip are converted into electrical signal output.
Monocrystalline silicon differential pressure transmitter
The sensor used in the monocrystalline silicon differential pressure transmitter utilizes the piezoresistive effect of monocrystalline silicon.When single crystal silicon material is subjected to axial stress, its resistivity will change. This phenomenon is called the piezoresistive effect.
Applications of Breeze Differential Pressure Transmitter
Flow Measurement
By measuring the pressure difference across a restriction, such as an orifice plate, venturi tube, or pitot tube, the flow rate of fluids can be accurately determined. This is critical in industries like oil and gas, chemical processing, and water treatment.
Level Measurement
Differential pressure transmitters are used to measure the level of liquids in tanks and vessels. By comparing the pressure at the bottom of the tank to the pressure at the top, the 1 liquid level can be calculated. This is particularly useful in applications where direct level measurement is difficult or impractical.
Filter Monitoring
In filtration systems, differential pressure transmitters monitor the pressure drop across filters. A significant increase in pressure drop indicates that the filter is becoming clogged and needs to be cleaned or replaced. This ensures optimal filtration performance and prevents equipment damage.
Pressure Drop Monitoring
Monitoring pressure drops across various components, such as heat exchangers or pipelines, is essential for identifying potential problems like blockages or leaks. Differential pressure transmitters provide accurate and reliable data for this purpose.
Components of Breeze Differential Pressure Transmitter
Direct pressure sensing element (located in the lower compartment).
Most industrial differential pressure transmitters are equipped with diaphragm as a pressure sensing element. This diaphragm is a mechanical device. It is placed between the two pressure inlet ports. The diaphragm will be deflected by the applied pressure.
This deflection is converted into an electrical signal. This is usually done by the sensors. Commonly used sensors are (a) Voltage meter (b) Differential capacitance (c) Vibrating wire. The sensor output is proportional to the applied pressure.
Electronic Unit
The electrical signal generated in the lower chamber by the sensor is only in the milli-volt range.
This signal must be amplified to the 0-5V or 0-10V range or converted to 4-20mA for later transmission to a remote instrument. This upper enclosure is the transmitter portion of the differential pressure transmitter that houses the electronics unit.
4-20mA 2-wire current transmitter
A DC output current is generated that is directly proportional to the pressure range of the differential pressure transmitter. The lower range is 4mA and the upper range is 20mA. This controlled current output is unaffected by load impedance variation and supply voltage fluctuations. This 4-20 mA output overlaps with BRAIN or HART FSK protocol digital communications
A differential pressure transmitter is a transmitter that measures the difference in pressure at both ends of the transmitter and outputs a standard signal (such as 4~20mA, 0~5V). Differential pressure transmitters are different from ordinary pressure transmitters in that they have two pressure interfaces.
Differential pressure transmitters are generally divided into positive pressure end and negative pressure end.
Generally, the pressure at the positive pressure end of the differential pressure transmitter should be greater than the pressure at the negative pressure section before measurement can be made.
The differential pressure from the pressure-conducting pipes on both sides acts directly on the isolation diaphragms on both sides of the transmitter sensor. The sealing liquid in the diaphragm is conducted to the measuring element.
The measuring element converts the measured differential pressure signal into a corresponding electrical signal and passes it to the converter. After amplification and other processing, it becomes a standard electrical signal output.

Install of Breeze Differential Pressure Transmitter
①Prevent the differential pressure transmitter from direct contact with corrosive or overheated measured media;
②Prevent debris from depositing and clogging in the pressure pipe;
③The length of the pressure pipes on both sides of the positive and negative pressure transmitter should be as consistent as possible;
④The liquid column pressure heads in the pressure pipes on both sides of the positive and negative pressure transmitters should be balanced;
⑤The pressure pipe should be installed where the temperature gradient and temperature fluctuation are minimal.
When measuring liquid flow, the differential pressure transmitter should be installed next to or below the pipe being measured so that bubbles can be discharged into the pipe;
When measuring gas flow, the differential pressure transmitter should be installed next to or above the pipe being measured so that the accumulated liquid can easily flow into the pipe;
When measuring steam flow, the differential pressure transmitter should be installed below the pipe to be measured so that the condensed water can fill the pressure pipe.
Special attention should be paid to preventing the temperature of the differential pressure transmitter from contacting the medium exceeding the limit temperature of the transmitter when measuring steam or other high-temperature media.
Calibration
First adjust the damping to zero state, first adjust the zero point. Then add the full pressure and adjust the full range so that the output is 20mA.
On-site adjustment is all about fast. Here we introduce the quick adjustment method of zero point and range.
When adjusting the zero point, it has almost no impact on the full scale. However, when adjusting the full scale, it has an impact on the zero point. Without migration, its impact is about 1/5 of the range adjustment amount, that is, the range is adjusted upward by 1mA. The zero point will move upward by about 0.2mA. ,vice versa.
After the zero point and full scale adjustment are normal, check the middle scales to see if they are out of tolerance. Make fine adjustments if necessary. Then adjust migration, linearity, and damping.
