DeltaSpan™ LD31 IS Submersible Pressure Level Transmitter

Application

The intrinsically safe submersible pressure level transmitter provides continuous level measurement up to 46' (14m) of water column with a 4-20 mA signal output. Select the LD31 liquid level sensor for relatively clean water, light weight oil or diluted chemical. Application examples include wet wells and water remediation.

Features

Corrosion resistant 316 SS body with polyurethane or ETFE cable

Strong cable design with maintenance free breather tube and vent filter

Automatic temperature compensation for accurate measurement
