1. * Ambient temperature = 77°F (25°C), unless otherwise noted.

2. Output span of unamplified sensor using the current set resistor and the circuit

shown in the schematic drawing.

3. Compensation resistors are an integral part of the sensor package; no additional

external resistors are required. Pins 7 and 8 must be kept open. The NPC-1220

is interchangeable only when used with the current set resistor shown in the

schematic diagram.

4. Best fit straight line.

5. Temperature range 32°F to 140°F (0°C to 60°C), reference to 77°F (25°C).

6. 3X or 200 psi (13.78 bar) maximum, whichever is less.

7. Exposed materials are pyrex, ceramic, silicon, epoxy, RTV, and stainless steel..
