Introduction:

Pressure sensors are critical components in medical devices, industrial automation, automotive systems, and IoT applications. Three popular series—MPS (Merit Sensor/TE Connectivity), PSG (Amphenol Advanced Sensors), and XGZP (Cynergy3/Amphenol)—stand out for their reliability, accuracy, and versatility.

But how do you decide which one is best for your project?

In this blog, we’ll compare these three sensor families in terms of:

• MPS Series (Merit Sensor / TE Connectivity)
• PSG Series (Amphenol Advanced Sensors)
• XGZP Series (Cynergy3 / Amphenol)
• Comparison Table: MPS vs. PSG vs. XGZP
• How to Choose the Right Pressure Sensor?

1. MPS Series (Merit Sensor / TE Connectivity) – The Rugged Workhorse

Technology & Key Features

• Type: MEMS piezoresistive pressure sensor

• Output: Analog (mV or amplified voltage)

• Pressure Range: 40 mbar to 10 bar

• Accuracy: ±1% FS (typical)

• Power Consumption: ~1 mA

• Package: DFN, DIP, ported options

Pros & Cons

✅ Low cost – Ideal for budget-sensitive projects
✅ Robust – Good for harsh environments
❌ No digital output – Requires external ADC for microcontroller interfacing
❌ Limited compensation – Some models need manual calibration

Best Applications

• Medical ventilators & infusion pumps

• Industrial pressure monitoring

• HVAC systems

2. PSG Series (Amphenol Advanced Sensors) – High-Precision Performer

Technology & Key Features

• Type: MEMS with integrated ASIC (signal conditioning)

• Output: Analog (0.5–4.5V) or Digital (I²C/SPI)

• Pressure Range: 1 mbar to 100 bar

• Accuracy: Up to ±0.1% FS (calibrated models)

• Power Consumption: ~100 µA (active)

• Package: SMD, ported, IP67-rated options

Pros & Cons

✅ High accuracy – Best for precision applications
✅ Wide pressure range – Supports up to 100 bar
✅ Flexible output (Analog or Digital)
❌ Higher cost than MPS
❌ Larger footprint for high-pressure models

Best Applications

• Automotive (tire pressure, brake systems)

• Industrial automation

• White goods (refrigerators, washing machines)

3. XGZP Series (Cynergy3 / Amphenol) – The IoT & Wearables Champion

Technology & Key Features

• Type: MEMS with digital ASIC

• Output: I²C/SPI (digital) or Analog

• Pressure Range: 1 mbar to 10 bar

• Accuracy: ±0.25% FS

• Power Consumption: As low as 1 µA (sleep mode)

• Package: Ultra-compact (e.g., 3.3 × 3.3 mm DFN)

Pros & Cons

✅ Ultra-low power – Perfect for battery-powered devices
✅ Tiny footprint – Fits wearables & IoT gadgets
✅ Digital interface – Easy MCU integration
❌ Lower pressure range (max 10 bar)
❌ Not ideal for extreme environments

Best Applications

• Smartwatches & fitness trackers

• Medical inhalers

• Smart home sensors (air quality, HVAC)
