etra System’s Model 524 new slim-line,

fully immersible pressure transducers are

S

ideal for industrial and residential water
level applications that require exceptional long­term stability, immersibility, and high accuracy.

Immersible to 200mwg, the Model 524 is rated
for IP68 operation. Its custom hermetic header
is triple sealed and guaranteed to eliminate the
potential of water intrusion in the transducer
even if the cable sheath is damaged.

All wetted parts are constructed of corrosion
resistant 316 Stainless Steel, Polyurethane, and
Acetal, which makes the sensor resistant to the
effects of condensation caused by a high
humidity environment, assuring long-term
stability and service.

The Model 524 offers 0.25% FS accuracy,
compensated temperature range of -15°F to
+120°F (-10°C to 50°C), operating temperatures
as low as -40°F to 180°F (-40°C to 80°C), and
gauge pressure ranges from 33 ft. WG (10m WG)
up to 656 ft. WG (200m WG).

The Model 524’s modular design is offered in
a wide choice of millivolt, voltage or current,
outputs over almost any pressure range, and a
variety of pressure and electrical connections,
enabling this unit to be custom configured for
your OEM application.

Principle of Operation

Micro-Electro-Mechanical Systems (MEMS)
brings together silicon-based microelectronics
with micromachining technology. The
electronics are fabricated using integrated
circuit process sequences (e.g., CMOS, Bipolar,
or BICMOS process,) and mechanical elements,
such as strain gauge sensors are fabricated
using compatible micromachining processes
that etch away part of the silicon wafer or add
new layers to form the mechanical and
electromechanical devices, providing a
complete system-on-a chip.
