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.

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
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.
