Page 5: Application
2 Application The Particulate matter-hygro-thermo-baro sensors from our COMPACT series are designed to measure the particulate matter values PM10 and PM 2.5, relative humidity, air temperature and barometric air pressure. The sensors are primarily intended for use in distributed particulate matter measurement net- works outdoors. -
Page 6: Measurements At High Humidity And Fog
The absolute air pressure is measured at the altitude of the sensor (measuring altitude, see drawing). Measuring altitude Particulate-Hygro- Thermo-Baro / 1.1007.54.78x (Cable end) Par- ticulate-Hygro- Thermo-Baro / 1.1007.54.78x Figure 1: Example Pressure Equalization The ambient air is sucked in at the lower end of the device for the particulate matter meas- urement. -

Page 8: Electrical Installation
6 Electrical Installation The electrical installation of the particulate matter-hygro-thermo-baro sensor is divided into two parts. The measuring electronics are connected via a plug connection, which is used both for the power supply and for communication. The ventilation of the weather and radia- tion protection is connected via a cable that is permanently connected to the device. -
Page 9: Connection Diagram
A cable for the measurement electronics is included. If a different cable is used, respect the following points. with cable assembly from Thies Clima. Depending on the variant, the unused cores may not be pre- sent. © Adolf Thies GmbH & Co. KG · Hauptstraße 76 · 37083 Göttingen · Germany 022032/07/24 Phone +49 551 79001-0 ·... -
Page 10: Plug And Cable Mounting (Optional)
The cable to be connected should have 4 wires, minimal wire cross-section 0.25mm² (AWG 23), cable diameter 6 … 8mm, resistant to ultraviolet rays, overall shielding. The following procedure is recommended for using the cable shield: Connect the cable shield between the sensor and the data acquisition system (e.g., datalog- ger) on both sides. -
Page 11: Connection Of The Ventilation
6.2 Connection of the ventilation 6.2.1 Cable assignment The permanently connected cable for the ventilation is assigned as follows: Figure 3: Ventilation connection diagram 6.2.2 Fan status The status output indicates the condition of the fan. A high signal expresses that the fan is working correctly, if the output is 0V there is a malfunction. -
Page 12: Maintenance
7 Maintenance The particulate-hygro-thermo-baro sensor compact is supplied adjusted and calibrated. The weather and radiation protection contains a plug-in module for measuring relative humidity and air temperature (Hygro-Thermo module). The PT 1000 sensor is optimally aligned at the factory. It should not be bent any other way. Although dust deposits do not damage the humidity sensor, they may impair the dynamic behaviour. - Page 13 Do not touch the highly sensitive hygro-thermo sensor element on the sensor surface. Sensor PT1000 Sensor surface Protective jacket Figure 7: Hygro-thermo Measuring Element The white protective jacket on the hygro-thermo sensor element must not be removed. If used with a filter cap, this should also be cleaned or replaced as required. When the pro- tective cap or filter cap has been removed, the Hygro-Thermo module can also be pulled up to clean or replace it.
-
Page 14: Firmware Update
Particular attention must be paid to the correct seating of the hygro-thermo module and the protective or filter cap, as these also ensure the tightness of the device. The particulate matter sensor does not have to be serviced, but is automatically cleaned. Sensor cleaning only takes place regularly when the power supply is uninterrupted. -
Page 15: Interface
10 Interface The interface to the sensor consists of an RS485 connection (half duplex mode) with the fol- lowing interface parameters • 9600 baud • 8 data bits • No parity bit • 1 stop bit • Data in ASCII format (command interpreter: THIES) •... - Page 16 Parameter: Parameter value with 1 to 10 places (decimal value in ASCII format di- rectly following the command without blanks) <CR>: Carriage return (13 ; 0x0D) The identification number 'id' can be used to operate several devices together in the bus sys- tem.
