Flowline-DeltaSpan™ IS Submersible Pressure Level Transmitter ( Model: LD31-IS )

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
