1240 mV Output Pressure Sensor

Brand: American Sensor Technologies Inc
Request Information Favorite
The 1240 is a high performance temperature compensated, piezoresistive silicon pressure sensor packaged in a dual-in-line configuration.

It is intended for cost sensitive applications where excellent performance and long-term stability are required. When using the 1240 with a fixed voltage reference and current set resistor as shown in the application schematic, a span of 50mV and 1% interchangeability can be achieved. 

Integral temperature compensation is provided over a range of -20° to 85° C using laser-trimmed resistors. 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 information on products with operating pressures less than 0 to15 psi. For current excitation, please refer to the Model 1230.
