The PX709GW Series submersible
depth transducers are designed
to make precision level or depth
measurements in fresh water or
liquids compatible with 316 SS
reliably for years in harsh industrial
environments. The PX709GW
Economical Price
High Performance
series has the proven Omega
micromachined silicon technology as
its core sensor. The Piezoresistive
technology uses precision solid state
strain gages molecularly embedded
into a highly stable silicon wafer.
The silicon is mounted in a sealed
chamber and protected from the
environmental fluids by a pressure
sensitive stainless steel diaphragm.
A very small volume of silicone
oil transfers the pressure from the
diaphragm to the silicon sensor.
The cable is molded onto the case
using a unique high pressure, high
temperature system to assure the
best possible quality seal for long
life and durability. This technology
produces a very rugged, high
stability sensor with exceptional
accuracy, minimal thermal effects
and long term reliability.

Nose cone included.
Applications
• Level Monitoring and Control
• Depth Measurement
• Surface Water Monitoring
• Tank Level
• Well Water Depth
• Waste Water Applications
• Dewatering Installations
• Construction Bypass
Inconel® models are also available for
oceanic research and highly corrosive
or salt water applications. See model

STANDARD CABLE LENGTHS FOR FAST DELIVERY
OMEGA® has designed the PX709 Series to be highly
modular so we can configure and ship most models in
1 week. We stock the modules and can quickly
assemble and do precision calibrations for any of our
several thousand possible combinations. The cable molded
onto the transducer using a high pressure, temperature
molding process to assure complete sealing. We stock a
series of molded cable assemblies in standard lengths to
suit most common applications which we can build onto your
transducer and deliver in 1 week (see the list below). We also
can provide custom lengths with slightly longer lead times to
allow for the molding process.
