Description
The NPC-1210 series of solid-state pressure sensors
are designed to provide a cost effective solution for
applications that require calibrated performance over
a wide temperature range. Packaged in a dual-in-line
conguration,theNPC-1210Seriesisintendedfor
printed circuit board mounting. Optional pressure port
andleadcongurationsprovidesuperiorexibilityin
lowproleapplicationswherepressureconnection
orientation is critical.
The NPC-1210 series is based on NovaSensor’s
advanced SenStable® piezoresistive sensing
technology. Silicon micromachining techniques
are used to ion implant piezoresistive strain gages
intoaWheatstonebridgeconguration.TheNPC-
1210 Series offers the added advantage of superior
temperature performance over the temperature
compensated range of 0°C to 60°C (32°F to 140°F). A
gain set resistor is included to normalize the FSO for
eldinterchangeability.

1. All dimensions are for reference only.
2. Tube length: L = 0.49 in (12 mm), S = 0.33 in (8.3 mm), N = No tube
3. Lead pins can be either in the same or the opposite direction of the pressure tube. Option (1) has the leads
in the "Up" position, the same direction as the tube. Option (3) has the leads in the "Down" position, the
opposite direction from the tube.
4. Gauge and differential pressure devices are calibrated by applying pressure to the positive differential port (P2)
and venting to atmosphere the reference port (P1). Absolute pressure devices use only P1 to apply vacuum or
pressure.

* 1. Supply current = 1.5 mA and ambient temperature = 77°F (25°C),
unless otherwise noted. Gauge and differential pressure devices are calibrated
by applying pressure to the positive differential port (P2) and venting to
atmosphere the reference port (P1).
2. Output span of unamplified sensor.
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-1210 is interchangeable only when used with the gain set resistor
shown in the schematic diagram. Maximum gain-set resistor mismatch is 2%.
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.
8. 5 psi (0.34 bar) spec.: Linearity: 0.25 ±%FSO, TC-span:
0.75 ±%FSO, TC-zero: 0.75 ±%FSO. otherwise noted.
