Flowline LD31-S121 DeltaSpan LD31 Submersible Pressure Level Transmitter, 34 ft. Range

Description

The LD31 general purpose submersible pressure level transmitter provides continuous liquid level measurement up to 34.65’ (10.5m) of water column with a 4-20 mA signal output. Offered in three level measurement ranges, select the appropriate model based on your tank height or well depth. For convenient installation with junction box termination, package your level sensor with the pressure sensor mounting kit. Each kit includes a junction box with terminal strip, mounting plug and liquid tight cable connector. The LD31 level pressure sensor is well suited for clean liquids compatible with 316 SS and polyurethane such as well water and diluted chemicals.
