RSA-PDG Multifunction Digital Differential Pressure Gauge
Applications & Features
- Apply high accuracy MEMS sensor and digital technologies, can measure positive,negative or differential pressure. It can replace most of the traditional pointer mechanical gauges.
- It combines the gauge and two relays for control function
- It can measure and control system pressure of fan, blower, filter, furnace draft and orifice plate and can apply to various clean room, biological safety cabinet, clean bench, ducts collection, medical or pharmaceutical machine, etc.
- Suitable for surface, panel or flush mount
- Multiple ranges and engineering units selectable
- No any movable parts, no any effect on vibration
- The accuracy is up to ±1% FS and the range can be 25pa
- Function keys: zero calibrate, units select, relay set, etc.
- Optional arch LED display for output and alarm

Accessory: A-S0 is standard including 2m/5mm ID tube, 3 pairs of screws and brackets. Options are A-S1, A-S2 and A-S7-X. They can be used for surface, panel or flush mount and should be ordered separately. See details in Accessories.
Models
The stardard electrical connection is cable from the back of the enclosure. If select screw terminals instead, add suffix T after the model number
Measuring Ranges
- 5 engineering units can be set by the key and then the related LED will be on.
- For zero center models, add“Z”at the end of the model. For example, RSA-PDG1***Z, means -30-0-30pa. Only ranges 1~6 have this selection.
