Introduction of air differential pressure transmitter:
The micro differential pressure transmitter is a device used to
measure the micro differential pressure. Its working principle is
based on piezoresistive sensor and differential pressure principle.
The differential pressure transmitter contains a piezoresistive
sensor, and the two ends of the sensor are connected with the two
sides of the measuring medium. When the medium passes through the
transmitter, a small pressure difference is generated on both
sides, resulting in a change in the resistance value inside the
sensor. This change will cause the sensor output signal to change,
and then generate the corresponding electrical signal output.
According to the change of the output signal of the sensor, the
micro differential pressure value of the medium can be accurately
calculated
1. The transmitter features a stainless steel structural design,
making it compact and easy to install
2. It undergoes strict temperature compensation and aging
screening, ensuring stable and reliable performances
3. The electrical interface can be selected as a plug-in or direct
wiring option.
Applications:
1. Suitable for measuring differential pressure of various gases or
liquids in pipelines of industries such as petroleum, chemical,
power, and hydrology.
2. Applied in industrial on-site processes such as petroleum,
chemica,metallurgy, power generation, and hydrology
3. Pressure measurement for pipelines and furnace chambers

1. When selecting the product, please ensure that the measured
medium is compatible with the product's contacting parts.
2. To ensure reliable operation, it is recommended to install a
three-valve manifold between the measurement point and the
transmitter, ensuring a slow and uniform pressure application to
the positive and negative pressure chambers of the transmitter.
3. During installation, it is advisable to position the pressure
interfaces at both ends horizontally to minimize the impact of the
installation location on the product.
4. For special requirements such as strong vibration, instant
impact force, strong electromagnetic interference, or radio
frequency interference, please inform our company and specify these
requirements in the order| Order Guide: |
