Model 205
Gauge & Absolute
Pressure Transducer
Setra’ s Model 205 is a high accuracy transducer for measuring gauge, absolute and compound pressure oering superior performance at an aordable price. Its single piece machined capacitance sensor enables accuracies up to ±0.073%
FS giving the 205 superior linearity to competitive sensors
that use two-piece welded sensing elements. The 205’s compact design oers customers a space saving solution for measuring pressure in Test and Measurement applications. The
205 has standard pressure ranges from 25 PSI to 5,000 PSI to
cover the most common pressure sensing applications.
High Accuracy For Demanding Applications
The Model 205 pressure transducer’s variable capacitance
design uses a single piece machined sensor, eliminating
failures from insucient welds. The sensor is linearized and
thermally compensated during manufacturing to optimize
the sensor’s linearity for maximum accuracy in demanding
Test & Measurement and OEM applications.

Excellent Stability
Small Footprint
The Model 205’s design oers high performance in a small
package. The sensor is only 1.75” wide by 2” tall, allowing
OEMs and test stand engineers to reduce the overall design
footprint of the end product.
High Performance Sensor
The Model 205 oers high price-to-performance sensor for
measuring absolute pressure. The simple congurable design enables the transducer to be congured for an absolute
reference by adding a hermetically sealed pressure reference
cap to the existing sensor design, allowing the price to remain aordable without sacricing quality.
