etra’s Model 546 and Model 547 pressure
transducers offer laboratory type
pressure measurement in a rugged
industrial housing complete with 5:1 range
turndown, ideal for high overpressure
applications, to provide full scale output from
25% to 125% of full range.
Utilizing thin film technology, Models 546 and
547 have 4 to 20 mA output, 0.1% Full Scale
accuracy, high overpressure capability, choice
of absolute, gauge, or sealed gauge pressure
measurement, and pressure ranges from
10 psi up to 10,000 psi. The compensated
temperature range is from -13°F up to +167°F.
Designed for use with corrosive media,
the Models 546 and 547 are offered with
17-4 PH stainless steel or Inconel (17-4 PH
and 15-7 Mo for ranges ≤30 psi) wetted parts
to provide years of maintenance free pressure
measurement in demanding industrial
applications. (Order Model 547 for pressure
transducer with Inconel® wetted parts.)

Depending upon the electrical connection
selected, when coupled with the Model 546/
547 enclosure, which is fabricated in 321 SS, 174 PH SS, and Glass-Filled Polyester, this unit is
rated for IP40, IP65, or IP68 operation.
Thin Film Strain Gauge Pressure Sensors
Using the well proven Wheatstone Bridge
principle, molecular layers are sputtered onto
a 17-4 PH stainless steel diaphragm and the
circuit is etched to provide excellent resistor
definition and uniformity. Sputtered thin film
technology allows the design of simple, highly
accurate and compact strain gauges
depositied onto the back of the sensing
diaphragm which is in direct contact with the
media. This method virtually eliminates drift,
while offering enhanced sensitivity.
