Pin Configuration
3 : DIP pins, opposite direction of tubes
5 : Surface mountable pins,
opposite direction of tubes
Tube Length
L : Long (0.480" ± 0.005")
N : No tube
Pressure Type
A : Absolute (1 port)
D : Differential (2 ports)
G : Gauge (1 port)
S : Single-ended (2 ports)
Notes
1. Absolute configuration only available in SM5822.
2. Single-ended configuration is for higher gain differential applications where differential pressure
is always positive.
3. Other configurations available on large orders. Consult SMI for details.
