The Hanla Pressure Type Level Transmitter is for continuously measuring the liquid level of ballast tank, draft and fuel oil tank in the marine ships as well as tanks containing media. The PL40 is a 2-wire, 4~20 mA level transmitter consisting of a transducer and an amplifier connected via a submersible vented cable. Pressure change in the front of the diaphragm will bring about a capacitance change in the cell of the transducer. This change will be transmitted to amplifier as a change in the electrical signal. The PL40 is manufactured in several ranges, and can be used to connect to the C.R.T. display cargo system, loading computer, indicator and analog type indicator to measure the actual level.
