NovaSensor NPC-1220 Series

Medium Pressure Sensors

The NovaSensor NPC-1220 Series of Medium Pressure Sensors are solid state pressure sensors that provide a cost effective solution for applications that require calibrated performance over a wide temperature range. Packaged in a dual-in-line configuration, the NPC-1220 Series is intended for printed circuit board mounting. Optional pressure port and lead configurations give superior flexibility in low profile applications where pressure connection orientation is critical.The NPC-1220 Series is based on NovaSensor’s advanced SenStable® piezoresistive sensing technology. Silicon micromachining techniques are used to ion implant piezoresistive strain gauges into a Wheatstone bridge configuration. The NPC-1220 Series offers the added advantage of superior temperature performance over the temperature compensated range of 32°F to 140°F (0°C to 60°C). A current set resistor is included to normalize the FSO for field interchangeability. Additionally, the NPC-1220 Series is available in pressure ranges from 0 psi to 5 psi (0 bar to 0.34 bar) through 0 psi to 100 psi (0 bar to 6.89 bar). Please contact us for other pressure ranges.

  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.
  9. Port 1 is limited to 60 PSIG for differential and absolute pressure sensors. Contact factory for 50 PSIA/D and 100 PSIA/D units.
