New high performance Level Pressure Sensors.
Druck announce a new generation of high performance
level pressure sensors, incorporating many enhanced
features gained from the company's experience in
supplying thousands of submersible sensors for a wide
range of small and large scale installations worldwide.
The new generation PDCR /PTX 1830 series is suitable for
industrial level measurements in many water and liquid control
applications. For potable water - ground borehole and surface
measurements in rivers, canals and reservoirs. Wastewater
monitoring includes secondary and outflow sewage and
contaminated ground water levels in land fill sites. Tank level
applications range from land based liquid storage vessels to
on-board ship ballast tank monitoring. Marine applications
include tide gauging, coastal/flood protection and wave profiling
amongst others.
A new all-titanium pressure sensing module fully encloses the
Druck micro-machined silicon element. This enhances durability
and compatibility with a wide range of liquid media.
Fullscale operating ranges are available from 0.75mH20 to up
to 600mH20 with a choice of electrical format. The 4 wire
transducer variant PDCR 1830 offers a fullscale signal of up to
100mV, whilst the transmitter variant PTX 1830 is a standard
2 wire 4-20mA device. For high precision applications, accuracy
is available up to +/- 0.06% and for pulse powered operations a
short switch-on time saves electrical power. An integral lightning
surge arrestor can be supplied, which protects against raised
earth potentials caused by surface lightning strikes.
The 1830 series is presented in a slimline 17.5mm casing
terminated in an injection moulded cable assembly. This is
strain relieved and IP68 rated for indefinite immersion to
700mH20.
Incremental 1m datum points are clearly marked on the cable
for quick and accurate alignment. A full range of accessories
further simplify installation, operation and maintenance. These
include a quick-release cable clamp assembly, slimline or short
profile sink weights, sensor termination enclosure and in-situ
pressure test/calibration adaptors.
A short delivery of typically 2 weeks is achieved by modular
design. Key pressure ranges are held in stock, simply requiring
final calibration and cable termination to fulfil customer orders.
