Page 8: Product Overview
It is also an excellent solution for monitoring barometric pressure in industrial equipment such as laser interferometers and engine test benches. In addition, PTB210 integrates directly with Vaisala Static Pressure Head Series SPH10/20. This pairing offers accurate measurement in all wind conditions. -
Page 9: Figure 1 Ptb210 With Standard Accessories
Chapter 2 – Product overview Figure 1 PTB210 with standard accessories PTB210 uses the Vaisala BAROCAP sensor, a silicon capacitive absolute pressure sensor developed by Vaisala for barometric pressure applications. The Vaisala BAROCAP sensor provides excellent hysteresis and repeatability characteristics and outstanding temperature and long-term stability. -

Page 11: Installation
Chapter 3 – Installation 3. Installation 3.1 Mounting PTB210 Due to the compact design of PTB210, you only need to mount the instrument and connect the wires. Choose one of the following 3 mounting options. • Remove the pressure fitting and place the barometer on a desired structure. Attach it with slot-headed screws the O-ring sealing the attachment (A). -
Page 12: Static Pressure Head
PTB210 has IP65 housing. You can mount it outdoors without any additional protection. Make sure that rainwater cannot block the open pressure fitting. Vaisala recommends connecting a piece of a tube with inner diameter of 4 mm or more to the fitting. -
Page 13: Connections
Chapter 3 – Installation 3.2 Connections There are 3 different serial output interfaces available for PTB210 digital barometers: • RS-232C • RS-485/232C • RS-232C/TTL The connections depend on the output protocol in use. Vaisala recommends isolating the free wire ends. -

Page 21: Self-Testing
Chapter 4 – Operation In case several barometers are connected to same line, set on only the resistor of the last one. The others must be off. This prevents formation of excessive load on the line. The maximum amount of barometers on same line is 32. At the end of the serial bus there must be PTB210, a dynamic line adapter, or a line master. - Page 22 PTB210 Series User Guide M210669EN-E .?<cr> (command not visible) PTB210 Ver 1.0 CAL DATE :1999-06-10 ID CODE :10 SERIAL NUMBER :T00100004 MULTIPOINTCORR:ON MEAS PER MINUTE: 60 AVERAGING : 0 PRESSURE UNIT : hPa Pressure Min...Max: 500 1100 (50 1100 for model 50…1100)

Page 23: Calibration And Adjustment
• For the Class A barometers, use standards with uncertainty of 70 ppm (2 standard deviation value), or better. • For the Class B barometers, Vaisala recommends electronic working standards with uncertainty of 150 ppm. Calibration does not include any adjustments. - Page 24 PTB210 Series User Guide M210669EN-E The Wizard software uses the RS-232 or RS-485 interface. If you use the TTL level, disconnect the RXD/TXD wires and connect the RX/TX wires. See Table 2 (page 12). 1. Go to http://www.vaisala.com/PTB210Wizard/. PTB210_calibration_wizard.zip downloads.
