LM 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.

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.
