This document introduces the features, characteristics and usage of the Vaisala PTB110 series barometer. The barometer is based on microelectric control and outputs voltage or frequency. It has multiple pressure ranges and the output values are calibrated values. The barometer uses Vaisala's proprietary BAROCAP® sensor, which has high accuracy and reliable measurement characteristics.
This manual describes how to install the PTB110 pressure sensor, including indoor mounting and optional outdoor enclosure, wiring options (three‑wire or four‑wire), and power‑on procedures. It also explains the normal and calibration modes, jumper settings, and the functions of the sensor terminals.
Technical specifications such as pressure range, accuracy, power supply, current consumption, output voltage, temperature limits and environmental protection rating are listed, together with safety warnings, ESD protection guidelines, and warranty terms. This manual is written in Chinese.
| Pressure range | 0 hPa abs to 2000 hPa abs |
|---|---|
| Accuracy at +20 °C | +0.3 hPa |
| Power supply | 10 VDC – 30 VDC |
| Current consumption | < 4 mA (normal), < 1 µA (shutdown) |
| Output voltage | 0 VDC – 2.5 VDC (or 0 VDC – 5 VDC) |
