Technical Overview
The Omron PS-31 SUS304 300MM is an integrated electrode holder with three SUS304 electrode rods, each 300 mm long and 4 mm thick. Omron positions the PS-31 for installations with limited space; the electrodes are integral and cannot be extended, removed or replaced, but may be cut to the required length. Manufacturer selection information lists an approximate mass of 325 g for the PS-31 assembly.
Compact integrated three-electrode holder with 300 mm × 4 mm SUS304 rods.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Compact tank level sensing
Use an integrated electrode assembly where a conventional separate holder would not fit the available space.
Potential use
Connect to a compatible Omron 61F controller and cut rods to the required level positions; confirm liquid compatibility and installation clearances.
3 electrodes
300 mm
compact mounting
2. Small sump or vessel monitoring
Provide conductive liquid-level feedback in a small tank or installation space.
Potential use
Use the fixed SUS304 rods as supplied, since the electrodes cannot be replaced or extended, and verify the liquid conducts sufficiently.
