Introduction

• The PL3700 has been developed for level measuring in tanks, ballast, oil, fresh water, chemical product… It also covers drafts measuring, pressure measuring in cargo line and inert gas measuring

• The PL3700 is a 2-wires 4-20mA level and pressure transmitter consisting of a transducer and an amplifier connected via a 3-core shielded/vented cable

• The PL3700’s transducer can be immersed and mounted inside tank using adapted bracket or on side mounting using adapted flange

• The transducer is fully welded and it is submersible, housed in stainless steel 316L or composite, using a capacitive ceramic diaphragm

• The amplifier is housed inside sea-water resistant polyester casing (IP66) which can be installed inside area protected against wave effect damage. The amplifier can be housed inside sea water-resistant stainless steel AISI 316L casing for open-deck installation

• A special model exists for Atmospheric Pressure Measurement (ATMO).

Main advantages

• wide thermal range of operation (up to 125°C) with an active temperature

compensation.

• excellent and stable accuracy (+/- 0.2 %)

• mechanical ruggedness allowing resistance to overpressure and corrosion

• built-in ASIC

• Intrinsic safety design
