DP transmitters are Differential Pressure Transmitters. DP transmitter measures the pressure difference between the gas or liquid at both ends of the transmitter. Output 4~20mA, 0~5V. Used for liquid level, density and pressure of liquid, gas and steam.

DP transmitters are different from pressure transmitters as they have 2 pressure interfaces. With flanges, capillaries, valve, brackets, throttle devices. Differential pressure transmitters are used to measure the level, density, and flow of liquids, gases, and vapors. Then convert it into 4–20mADC current signal output.
Sino-Inst offers a variety of DP transmitters for industrial pressure measurement. If you have any questions, please contact our sales engineers.
Featured DP transmitters
Piezoresistive Differential Pressure Transmitter utilizes the piezoresistive effect of semiconductor silicon materials. Realize accurate measurement of differential pressure.
Smart Differential Pressure Transmitter measures industrial differential pressure. Can Works with diaphragm seals, capillary, HART. Outputs standard signals (such as 4 ~ 20mA, 0 ~ 5V).
Flange Mounted Differential Pressure Transmitter is also called single flange DP level transmitter. For liquid, gas or vapor pressure measurement.
Extended Diaphragm Seal DP Transmitter is a level transmitter direct mounted on pipe or tank. The isolation diaphragm is in direct contact with the liquid medium.
Remote Seal DP Transmitter is often used as a tank level transmitter. The smart pressure transmitter is connected with a stainless steel flange by capillary. The pressure is sensed by a remote transmission device installed on a pipe or container.
Differential pressure (DP) level transmitter is a perfect solution for tank level measurement. Flanges, seal diaphragms, capillaries, and DP transmitter are often used to measure liquid levels.
Quickly measure the positive, negative or DP of air or non-corrosive gas. Sino-Inst supplies Differential Pressure Gauges made in China. DWYER 2000 Differential Pressure Gauges, Magnehelic differential pressure gauges are also available.
Differential Pressure Transmitters Technology Guide
What is a Differential Pressure Transmitter?
Differential pressure (DP) transmitter, also known as differential pressure transducer. The most common and useful industrial pressure measuring instrument is DP transmitter.
A differential pressure transmitter measures the difference between two pressures. The differential pressure transmitter converts the pressure measurement to a proportional 4-20 mA or 1-5 Vdc output signal. Used as input for controllers, recorders, indicators or similar devices.
The DP transmitter will sense the pressure difference between the two ports according to the calibrated pressure range and generate an output signal. Industrial differential pressure transmitters are made of two housings.
The pressure sensing element is located in the lower half, and the electronic element is located in the upper half. It will have two pressure ports labeled “High” and “Low”. The high-pressure port is always in a high-pressure state. It is not mandatory that the low-voltage port is always in a low-voltage state. This mark is related to the effect of the port on the output signal.
DP readings can be negative or positive, depending on the low-end or high-end. If the low-pressure side is open to the atmosphere, the DP transmitter can be used as a gauge pressure transmitter.
Through its 4… 20 mA, HART®, PROFIBUS®PA or FOUNDATION Fieldbus ™ output signal, combined with intrinsic safety or fire protection.
Differential pressure transmitters are suitable for applications that require these functions. All electronic devices with explosion-proof transmitters are safe. Therefore, the instrument can be adjusted in the EX area when the instrument is energized.
Sino-Instrument’s DP transmitters can work with AMS TREX device.
Features of DP transmitters
- Widely used
DP transmitters are the basic measurement equipment in industrial measurement. Under different measurement environments, pressure, liquid level, flow, and density can be measured. - Suitable for harsh working conditions
High temperature, explosion-proof and anti-corrosion can use DP transmitters. By adding flanges, capillaries, brackets, etc., remote measurement can be performed.
