The Vaisala PDT102 micro differential pressure transmitter is a high-performance instrument primarily designed for life science and cleanroom applications. The PDT102 has a 0.25% or 0.5% full-scale accuracy, a 250 ms response time, a 1 x 10-4 full-scale electrical resolution, and can measure a range of ±50 Pa or ±0.25 in. w.c.
The Vaisala PDT102 is a high‑performance differential pressure transmitter designed for life‑science and clean‑room applications. This quick guide provides essential installation instructions, wiring diagrams, and calibration procedures while noting safety considerations such as over‑pressure limits and ESD protection.
Key sections cover technical specifications, electrical wiring (voltage and current output), mechanical mounting on DIN rails, and step‑by‑step calibration using the optional front‑end test device or process valve driver.
| Measurement range | +50 Pa or +0.25 inH₂O |
|---|---|
| Over‑pressure rating | 0.7 bar |
| Power supply voltage | 12 VDC – 36 VDC |
| Output signal | 4–20 mA (2‑wire) or 0–5 V (3‑wire) |
