NPI-19A-CZ021GH Pressure Sensor Detailed Specifications
The NPI-19A-CZ021GH is an industrial-grade pressure sensor from the
NPI-19 series of NovaSensor, a brand under Amphenol. It is mainly
designed for low-pressure measurement scenarios, adopting
dielectric isolation technology and piezoresistive sensing process,
which combines high precision and high reliability. The following
are its detailed parameters and key information:
1. Core Technical Parameters
1.1 Pressure-related Parameters
Measurement Type: Gauge Pressure
Standard Measuring Range: 0~2.5 psi (equivalent to 0~17.2 kPa, 1
psi ≈ 7 kPa)
Maximum Overload Pressure: 3 times the rated pressure (for constant
current power supply), 2 times the rated pressure (for constant
voltage power supply)
Static Accuracy: ±0.1% FSO (typical value), ±0.5% FSO (maximum
value), including linearity, repeatability and hysteresis errors
Temperature Compensation Range: 0~70℃ (32~158°F), the maximum
temperature error after compensation is ≤0.75% FSO
Environmental and Physical Parameters
2.1 Environmental Adaptability
Operating Temperature: -40~125℃ (-40~257°F)
Storage Temperature: -40~125℃ (-40~257°F)
Humidity Adaptability: No clear indication, it is recommended to
avoid condensing environment (compatible with conventional
industrial humidity)
Vibration Resistance: Supports conventional industrial vibration
environment at a frequency of 20~2000Hz (specific values not
specified, refer to series characteristics)
Shock Resistance: Supports industrial-grade shock strength under
11ms pulse (refer to the 100g shock resistance characteristics of
the series)
2.2 Physical and Structural Parameters
Main Material: 316 stainless steel isolation diaphragm, compatible
with 316SS adaptive media (strong corrosion resistance)
Dimension Specifications: Cylindrical structure, diameter
18.8~19mm, length 7~7.1mm (standard NPI-19 series size)
Weight: Approximately 10 grams (lightweight design, easy for
integration)
Pressure Port: No built-in port (needs to be matched with an
adaptive port module), supports welded seal/side seal design,
optional thread interfaces such as 1/2"-20 UNF, 1/4"-18 NPT
Sealing Specification: Type A configuration includes O-ring (size
φ16.76×0.99mm) to ensure sealing performance
Packaging Form: Tube (tubular packaging), convenient for storage
and transportation
3. Product Features and Application Scenarios
3.1 Core Advantages
Dielectric Isolation Design: The sensor chip is packaged in an
oil-filled cavity, and the measuring medium is isolated by a
stainless steel diaphragm to avoid chip damage caused by corrosion
or pollution
Advanced Technology: Adopts Senstable® piezoresistive sensing
technology, and the hybrid ceramic substrate integrates a
temperature compensation resistor network, with excellent stability
Dual Power Supply Modes: Supports constant current (1.5mA) or
constant voltage (10V DC) power supply, adapting to different
system design requirements
Long Service Life: The pressure cycle life is about 10 million
times, with small long-term drift and strong durability in
industrial scenarios
3.2 Typical Applications
Liquid/gas pressure control systems, industrial process detection
and automatic control
Energy management, environmental protection and water treatment
systems (such as bridge water level detection)
Marine navigation systems, refrigeration and oxygen generation
equipment, diesel engine systems, agricultural machinery equipment
HVAC (Heating, Ventilation and Air Conditioning) systems,
biomedical instruments and other low-pressure and high-precision
measurement scenarios
