The PTX/PDCR 1280/1880 Series submersible/depth
pressure transducers are specifically designed for
depth/level measurements in the groundwater, well
water, canals, rivers and other similar applications. The
all-titanium construction ensures excellent life in the most
hostile environments, including corrosive and hazardous
chemical applications. GE backs its titanium construction
with a five year corrosion warranty. standard vented
cable is flouropolymer. Polyurethane cable is available on
the Series 1230 or 1830.
The PTX/PDCR 1280/1880 Series sensors are ideal for use
in applications where smaller size is an advantage, such
as municipal water supply wells, leachate wells, irrigation
projects, etc. The titanium construction also makes the
devices suitable for seawater and chemical tank
measurement applications.
An advanced micromachined silicon piezoresistive
pressure sensor provides excellent performance and
resistance to shock and vibration. A tough, flouropolymer
cable is attached to the transducer body, providing a
high integrity, waterproof assembly. The cable is
strengthened with Kevlar
®
so that there is no measurable
elongation when the cable is lowered into deep wells.
The fully isolated, all titanium design ensures long term
reliable measurements in water and wastewater
management, industrial, process and marine
applications.
