Pressure transducer model 47 (ultra-stable)

The Model 47 is a high performance, temperature compensated, piezoresistive silicon pressure sensor packaged in a differential TO-8 configuration.

It provides excellent performance and long-term stability.

Modelo 47

Differential pressure ranges from 0-15 PSI to 0-250 PSI are available.

Integral temperature compensation is provided over a range of -20°C to +85°C using laser-trimmed resistors. An additional laser-trimmed resistor is included to normalize pressure sensitivity variations by programming the gain of an external differential amplifier. This provides sensitivity interchangeability of ±1%.

Please refer to the low pressure section for information on products with operating pressures less than 0-2 PSI.
