RSA-TPDG Multifunctional Digital Differential Pressure Transmitter
Applications & Features
- Apply high accuracy MEMS sensor and digital technologies, can measure positive, negative or differential pressure
- It combines the gauge, two relays and transmitter in one unit, can supply measurement, digital display, on/off control and transmitter output simultaneously
- 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, outputs and engineering units selectable
- No any movable parts, no any effect on vibration
- The accuracy is up to ±1%
- Function keys: zero/range calibrate, units select, relay set, output calibrate, 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-TPDG1***Z, means -30-0-30pa. Only ranges 1~6 have this selection.
