Why Choose the PT230BN Micro Differential Pressure Transmitter?

1. Advanced SiGlas™ MEMS Sensor Technology

The PT230BN utilizes a single-crystal silicon diaphragm with variable capacitance sensing, offering:
✔ High accuracy (±0.25% FS typical)
✔ Excellent long-term stability – Minimal drift over time
✔ Overpressure protection – Withstands up to 10x rated pressure

2. TruAccuracy™ Calibration for Reliable Performance

Unlike traditional calibration methods, Ziasiot's TruAccuracy™ technology ensures:
✔ Endpoint linearization – Accounts for zero & full-scale errors
✔ Temperature-compensated output – Stable readings in fluctuating environments
✔ Factory-tested performance – No field recalibration needed

3. Robust Design for Demanding Applications

✔ IP65 protection – Resists dust and water ingress
✔ ABS/UL-V0 flame-retardant housing – Safe for industrial use
✔ Built-in buttons – Prevent accidental setting changes
✔ Optional LCD display (CGL15D model) – Real-time pressure monitoring
