Dry Air Differential Pressure Sensor Stainless Steel Structure Factory Gas Pressure Sensor
Dry Air Differential Pressure Sensor Stainless Steel Structure Factory Gas Pressure Sensor

The BP93420DI differential pressure transmitter accurately measures differential pressure through a Wheatstone bridge sensor chip that provides linear output relative to pressure changes. This instrument is engineered for precise measurement of gas and liquid differential pressures in industrial pipeline applications across petroleum, chemical, power, and hydrology sectors.

- Stainless steel construction for compact design and easy installation

When selecting this product, verify that the measured medium is compatible with the product's contacting parts. For reliable operation, install a three-valve manifold between the measurement point and transmitter to ensure slow, uniform pressure application to both positive and negative pressure chambers.
During installation, position pressure interfaces horizontally to minimize location impact. For special requirements including strong vibration, instant impact force, strong electromagnetic interference, or radio frequency interference, please specify these conditions in your order.
