316L SS Pressure Sensor with PVC Threads
Small Profile
4.5V (typ) High Level Output
Gage, Absolute, Sealed Gage
ASIC Calibrated
Variety of Cable Lengths
DESCRIPTION
The LM incorporates stainless steel and plastic isolation suitable for level sensing in water and other liquids. The
LM uses a patented low cost stainless steel sensor in a PVC plastic fitting. The modular design is adaptable to
an infinite number of plastic port variations. With high performance in a small form factor, the LM Series enables
the miniaturization of high accuracy pressure systems. The standard output is 4.5V with a 5V supply.

Notes
1. Ratiometric to supply voltage.
2. Measured at vacuum for Absolute (A), ambient for Gage (G) and Sealed Gage (S).
3. Best fit straight line.
4. Minimum from any wire to metal diaphragm.
5. The maximum pressure that can be applied without changing the transducer’s performance or accuracy
6. The maximum pressure that can be applied to a transducer without rupture of either the sensing element or transducer.
7. Over-torquing will damage the PVC fitting and will cause sensor calibration and/or zero offset to shift during installation. Always check
for a zero offset shift after installing.
8. Zero offset effect is inversely ratiometric to pressure range, for 2psiG: 0.3% Span (typ); for 5psiG: 0.12% Span (typ).
Additional Notes
9. Standard gage units are not recommended for vacuum applications.
10. Direct mechanical contact with diaphragm is prohibited. Diaphragm surface must remain free of defects (scratches, punctures, dents,
fingerprints, etc.) for device to operate properly. Caution is advised when handling parts with exposed diaphragms. Use protective cap
whenever devices are not in use.
