BP93420DI Differential Pressure Transmitter
Introduction:
BP93420DI is a Micro-differential pressure transmitter that utilizes the piezoresistive effect of semiconductor silicon material to convert differential pressure into an electrical signal. 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.

| Ordering tips |
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. For special requirements such as strong vibration, instantaneous impact force, strong electromagnetic interference, and radio frequency interference, please inform the company and specify them in the order.
