Differential Pressure Transmitter With Diffused Silicon Piezoresistive Dwyer Differential Pressure Sensor
BP93420DII Differential Pressure Transmitter
Introduction of differential pressure transmitter:
The BP93420DII differential pressure transmitter employs a diffused silicon piezoresistive sensor. The pressure differential of gas and liquid is measured and outputted, which can be displayed. It is applicable to the measurement of pressure differential of various gases and liquids in pipelines within industries such as petroleum, chemical, electric power, hydrology, etc.
Product Features of differential pressure transmitter:
- The transmitter adopts stainless steel structure design, compact structure and easy installation.
- After strict temperature compensation and aging screening, to ensure stable and reliable performance.
- The electrical interface can be external or direct connection.
Applications of differential pressure transmitter::
- 1. Suitable for the differential pressure measurement of various gases or liquids in pipelines in petroleum, chemical, electric power, hydrology and other industries.
- 2. Used in industrial field process control.
- 3. Pipe and furnace differential pressure measurement.ers

| Ordering tips of differential pressure transmitter: |
1. When selecting the product, please ensure that the test medium is compatible with the contact parts of the product (stainless steel 304 or 316L).
2. In order to ensure reliable operation, it is recommended to install three valve tubes between the measuring point and the transmitter to ensure that the pressure of the positive and negative pressure chamber of the transmitter is slow and uniform. If the overload of a single end is serious, the sensor will be damaged.
3. When installing, the pressure interfaces at both ends should be placed horizontally to minimize the impact of the installation position on the product.
4. In case of special requirements such as strong vibration, instantaneous shock, strong electromagnetic interference or radio frequency interference, please inform us and indicate in the order.
5.When ordering a transmitter with an LCD or LED display head, the power supply of the transmitter should not be lower than 20VDC.
