Temperature Sensors & Pressure Transducers O MY, You Look Tired -- Episode 513 Video

Sensors and Pressure Transducers: Ranges, Power Requirements, and Troubleshooting TipsThe hosts discuss travel fatigue, long commutes, and airport TSA delays that led to canceling a flight and driving instead, then shift to field work issues during store startups and CO2 conversions, including controller communication problems caused by cabling, IT security port shutdowns from new MAC addresses, and router performance differences. The main technical focus is identifying and troubleshooting pressure transducers and temperature sensors: common signal ranges (1–6V, 0.5–4.5V, 0–5V, 0–10V, and 4–20 mA), matching transducer power requirements (5V, 12V, 24V/24–36V), and selecting correct pressure ranges for applications up to CO2 gas coolers. They cover sensor types (PT1000, 10K2 vs 10K3, 2.2K, 3K, 86.3K), wiring/offset issues with PT1000 over distance, and using linear interpolation apps to convert measured voltage to expected pressure or controller readings. They briefly mention megger use and plan to discuss CO2 leak detection and drain-related concerns next week.
