Honeywell TruStability™ SSC Series Pressure Sensor Selection Guide
From Application to Part Number — Your Complete Selection Roadmap
Pressure sensor selection challenges many engineers and buyers: Which pressure range? Analog or digital output? What package type? How to decode the model number? Choosing wrong means poor accuracy — or worse, project delays and costly redesigns. This guide walks you through Honeywell's TruStability™ SSC series selection logic from real-world application scenarios — helping you lock in the right part number in 3 minutes.

1. Answer These 5 Questions Before You Start
- What are you measuring? — Absolute (vs. vacuum), Gauge (vs. atmosphere), or Differential (between two ports)?
- What pressure range? — Select 1.5–2× your normal operating pressure as full scale. Don't oversize — it dilutes accuracy.
- What's your downstream interface? — Direct ADC connection → analog output. MCU/processor via bus → digital I²C or SPI.
- How much board space? — SIP: smallest footprint (single inline). DIP: standard dual inline. SMT: surface mount for automated assembly.
- Gas or liquid? — Standard models measure gas only. For liquid, special options are required and range must be ≥40 mbar.
2. Pressure Range Quick-Lookup Table
| Pressure Range | Range Class | Typical Applications | Recommended Type | Series Code |
|---|---|---|---|---|
| ≤±10 mbar | Ultra-low differential | Leak detection, micro-flow | Differential | MD Series |
| ±10~±60 mbar | Low differential/gauge | HVAC, ventilators | Diff/Gauge | MD/NG/PG |
| ±60 mbar~±1 psi | Mid-low gauge | CPAP, flow monitoring | Gauge | PG Series |
| 1~15 psi | Common range | Medical/Industrial general | Gauge/Absolute | PG/PA Series |
| 15~150 psi | High pressure | Hydraulics, industrial process | Gauge/Absolute | PG/PA/BG |
3. Analog or Digital? Quick Comparison
| Feature | Analog Output | Digital Output (I²C/SPI) |
|---|---|---|
| Signal Chain | Sensor → ADC → MCU | Sensor → MCU (direct read) |
| Accuracy Loss | ADC resolution dependent | Internally quantized — no extra loss |
| Noise Immunity | Trace-sensitive, needs filtering | Digital — inherently immune |
| PCB Layout | Analog ground isolation needed | Standard I²C/SPI routing |
| Update Rate | ~1 kHz | ~2 kHz |
| Fault Detection | Not supported | Internal electrical fault detection |
| Best For | Simple loops, existing ADC | Smart devices, multi-sensor systems |
Recommendation: For new designs with an MCU, go digital (I²C/SPI) — simpler design, better reliability. For legacy analog systems, the analog version integrates seamlessly.

6. Engineer FAQs
Q1: SSC vs. HSC — which should I choose?
SSC is Standard Accuracy (TEB ±2%~±4%); HSC is High Accuracy (TEB ±1%). For extreme precision like medical metrology, choose HSC. For most medical and industrial applications, SSC offers sufficient accuracy with better cost-effectiveness.
Q2: What's the difference between compensated and operating temperature?
Compensated temperature range is where specifications are guaranteed. Operating temperature range is where the sensor functions but with potentially relaxed specs. Always design within the compensated range for critical measurements.
Q3: Can the SSC measure liquids?
Standard models measure gas only. With the liquid media option, models ≥40 mbar can measure non-corrosive, non-ionic liquids. Note: liquid only on Port 1 — Port 2 is not liquid-compatible.
Q4: What about overpressure capability?
SSC sensors use Honeywell's patented silicon ceramic technology with industry-leading burst pressure. Overpressure is typically 2× full scale, burst pressure higher. The sensor survives pressure spikes that would damage conventional designs.
Q5: Do I need external temperature compensation?
No. Every SSC sensor is factory-calibrated via onboard ASIC for offset, sensitivity, temperature effects, and non-linearity across the full pressure and temperature range. Read the output directly — no external compensation algorithms needed.
