Choosing a pressure transmitter by application
Choosing by measurement
| Measurement | Device | Note |
|---|---|---|
| Gauge pressure | Gauge transmitter | Steam, water, compressed air |
| Absolute pressure | Absolute transmitter | Vacuum, condensers |
| Draft, low DP | mbar/Pa DP transmitter | Furnaces, fans, cleanrooms |
| Differential pressure | DP transmitter + manifold | Filters, closed-tank level, flow |
| Dirty or hot media | Diaphragm seal + capillary | Slurry, food, chemicals |
Pressure transmitter standards
| Standard | Scope |

| IEC 61508 | Functional safety SIL 2/3 |
| ISO 5167 | DP flow measurement |
FAQ
Gauge vs absolute pressure?
Gauge is referenced to atmosphere, absolute to perfect vacuum: bar abs = bar g + 1.013.
Why a 3-valve manifold?
To isolate, equalise and zero a DP transmitter without removal, avoiding one-sided overpressure.
