1230 mV Output Pressure Sensor

Brand: American Sensor Technologies Inc
Request Information Favorite
The 1230 is a high performance temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration.

Integral temperature compensation is provided over a range of -20° 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%. Absolute, differential and gauge pressure ranges from 0 to15 to 0 to100 psi are available. Multiple lead and tube configurations are available for different applications. 

Please refer to the 1210 and 1220 for information on products with operating pressures less than 0 to15 psi. For voltage excitation, please refer to the Model 1240.
