    • The particulate may be inflammable, explosive or toxic • The gas can be hot and pressurised The S300 Series dust monitors do not have an internal circuit breaker. The customer has to install a separate circuit breaker to the power cable to ensure that the power can be isolated.

  • Page 4: Product Overview

    1.2 Product overview The S303 Trend monitor is a microprocessor-based, self-adjusting device, equipped with two alarm relays and a 4-20 mA signal output is designed for trend or filter bag leak detection. It can also be used to detect blockage or stoppage in pneumatic transport and bulk solids handling.

    2. INSTALLATION 2.1 Selecting the installation location The best location for installation of the units of the S300 Series is in a section of duct where the particulate has an even distribution and the flow is laminar. This is to ensure that the sensor rod comes into contact with a representative flow of particles.
  • Page 6 Figure 1. S303 Trend Monitor The unit shall be installed in a position, where the gas flow passes the sensor rod in a 90° angel. In round cross-section ducts, the unit can be installed in any position above the horizontal axis (between 9 o’clock and 3 o’clock). For square cross-section ducts, the unit must be positioned in the middle of the top or in the middle of one of the sides.

  • Page 7: Installing The Sensor

    2.2 Installing the sensor Once the location of the unit has been selected, the mounting socket must be welded to the pipe or duct. To do this, first cut a hole in the duct slightly larger than the OD of the mounting socket, 38 mm. The socket must be perpendicular to the flow in the duct.

  • Page 12: Operation

    6. OPERATION Operation of the monitor The S300 Series Dust Monitor measures the dust level in a gas stream by monitoring electrostatic discharge when charged dust particles hit or pass by the probe. It may have a 4…20 mA output (S302/S303), and/or two relay contact alarm outputs (S301, S302 and S303).

  • Page 18: Maintenance

    8. MAINTENANCE S303 Dust Monitor needs very little maintenance. To achieve maximum reliable operation the recommended maintenance interval is 2 months. Maintenance is done by removing the unit from the socket and cleaning the probe to prevent signal leakage to ground. If the particles in the gas are sticky and tend to build up, use air purge adaptor and compressed clean and dry process air to keep the sensor base clean.
