BP93420DI Differential Pressure Transmitter
Introduction of differential pressure transmitter:
BP93420DI is a Micro-differential pressure transmitter.It is mainly
used for measuring small differential pressures of non-corrosive
dry gases, suitable for applications in industries such as boiler
air supply, underground ventilation in the power and mining
industries, and pressure automatic detection in ultra-clean
workshops for process control.
Product Features of differential pressure transmitter
1.Choice of aluminum or plastic casing design
2.Lightweight and easy to install
3.Undergone rigorous high and low-temperature testing to ensure
wide temperature range usability
4.High accuracy
Applications of differential pressure transmitter:
1.Suitable for applications in boiler and mining industries
2.Brewing and power industries
3.Designed for detecting small differential pressures of
non-corrosive gases

1. When selecting the product, please ensure that the medium to be
measured is compatible with the product parts in contact.
2. To ensure reliable operation, ensure that the measured medium is
slowly and evenly pressurized on both the positive and negative
pressure chambers of the transmitter.
3. During installation, it is recommended to position the pressure
interfaces at both ends horizontally to minimize the impact on the
product due to the installation position.
4. Ensure that the measured medium is a dry gas.
