0-5" & 0-10" H2O Pressure Sensor With Compensated, Millivolt Output

The 1210 sub PSI is a 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.

Integrated temperature compensation is provided over a range of 0-60°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%. Differential pressure ranges from 0-5 to 0-10 in H2O are available. Multiple leads, metal or ceramic barbed tubes are available for specific applications.
