||37 UltraStable Pressure Sensor
The Model 37 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. Differential pressure ranges from 0-15psi to 0-250psi 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 0-2psi on.
