Electric Pressure Level System

Electric Pressure Type


The PL3700 is a ceramic family transmitter specially designed for sea water application thanks to its composite housing which avoid the electro chemical corrosion and sea water organic deposits. Mounted on a flange and protected by an external stainless steel casing, to prevent physical damage, it is specially made for side mounting application such as draft measurement or level measurement in tanks only side accessible. The PL37010 is linearised. The polyester remote electronic box includes the amplifier with zero and span adjustment. The pressure transducer is sealed inside a composite housing (IP68 rating).
