Catalog ZN-DPX21-S

 OMRON introduces Differential Pressure Station –clearly visualize differential pressure shifts at all times!

Ultra wide-range precision measurement
This ensures a range of minus 500 to plus 500 Pa and differential pressure accuracy of plus/minus 3%. With more accurate differential pressure control, clean room environments can be effectively maintained.

Built-in hybrid logging engine
Data can be logged to the unit (SD Card) while communicating with PC (or PLC) via LAN. Even in the event of network failure, the unit will continue to record data. Production technology divisions can centrally control management via network while manufacturing floors can localize control using SD cards.

Easily construct a wide range of control systems

Built-in alarm output makes the station an effective part of all kinds of control systems.
● Positive pressure level alert for clean environments
● Automatic control of air conditioning level based on differential pressure level

Simple visualization software included as a standard
Simple, user-friendly PC software is included as standard. Unit setup and data logging can be possible via LAN network.
Also, logged data can be easily displayed in a waveform graph.

With back-up using commercially available AAA batteries, operation continues even during sudden power outage

With built-in battery backup feature, LAN transmission and logging operation won’t stop even in the event of power outage or sudden disconnection.

* In network mode, operation continues for approximately two hours on batteries alone. However, battery life will vary depending on the measurement environment, battery type, or battery performance.

Positive pressure level in a clean booth is easily checked using this Differential Pressure Station


Calibration service also available!

A Certificate of Calibration can be issued upon request. (It is necessary to ship the product back to OMRON.)

To obtain a Certificate of Calibration at time of purchase, please select a type that includes a Certificate of Calibration.

As the sensor head and station are digitally connected, this calibration service is available only for the sensor head.
