This section describes the installation of the optional PCME Small Blower Unit for use with the PCME QAL 181 sensor. This may be used as an alternative to the use of instrument air. The blower is designed to supplying sufficient purge air (50 Litres/min) under normal stack conditions.
For large systems it is best to place the control unit in the centre of the network to minimise voltage drop along cables. For large systems you may need to boost power using a Power Supply Repeater – contact PCME for details.

Watch the instrument performance with the process running and ensure that the process is still being followed correctly. This is best done by downloading data using PCME Dust Reporter software. Compare the data before and after cleaning: if cleaning has significantly altered the reading then more regular maintenance may be required.
10 CALIBRATION 10.1 Introduction The PCME QAL 181 sensors attached to the control unit can be calibrated in mg/m³ in certain applications. Calibration of each sensor is necessary on at least an annual basis and should be carried out either by PCME or an authorised PCME representative.
