PTX/PDCR 1280/ 1880 Series

Druck Submersible Depth/Level Pressure Transmitters/Transducers

Features

PTX/PDCR 1280/1880 is a Druck product. Druck has joined other GE high-technology sensing businesses under a new name

GE Industrial, Sensing.

• All-welded titanium construction backed by five-year corrosion warranty

• Accuracy:

1880: < ±0.1% full scale (FS) best fit straight line (BSL)

1280: < ±0.25% FS BSL

• Ideally suited for underground fuel tanks

• FM, CSA intrinsically safe, CE marked

• Flouropolymer

cable

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.
