High precision, stability and a very good tightness class characterize these level sensors. We have 30 years of history with Swedish customers which shows absolute top class. The PDCR/PTX 1830 has a fully molded cable attachment with individual sealing of the conductors.
The sensors can be ordered with signal output mV (PDCR) or 4-20 mA (PTX). Measuring range can be from 0-0.7 mH2O to 0-700 mH2O with down to 0.06% FS inaccuracy.
The housing is made of titanium to ensure corrosion-free operation in e.g. sea water. Your small diameter of 17.5mm means that the sensors can be advantageously used in boreholes.
