Spero Group reports that the Oldham France EP1000 stack monitor is well received by various South African companies because of the unique features and stability of the product.
Outstanding features include:
* Installation is made easy with a sighting facility while the IP65-related enclosure allows adequate protection against the elements.
* The EP1000 is able to operate on stacks with gas temperatures of 500°C.
* Measurement range is from 0 to 10 g/m³ in 10 user selectable ranges. A unique feature is the ability to program up to 10 separate processes.
* An optical calibrator is also available for periodic checking of the laser diode.
* Standard outputs include 4-20 mA, RS485 or RS422 protocol.
* An optional remote display and keyboard for easy control.
* Waterproof cabinet enables outside mounting with ambient temperature range
-30 to +60°C (IP65).
* Does internal conversion from backscatter signal to output reading in mass/volume/g/m³).
* Ventilation and blowing mechanism integrated in the mantle prevents the optics from contamination, by creating an over pressure of air in from of the optics, especially in the chimneys with higher than atmospheric pressure. It also acts as a cooling mechanism for the instrument.
* The use of an airflow detector raises an alarm upon blower failure.
* An automatic internal zero check is done to ensure correct point operation. No regular span check is required due to controlled optical output of the laser diode and optical sensor technology.
* A span check can be done from time to time with the use of an external optical calibration tool.
* Excellent signal linearity, especially at low concentrations.
* No drift in measurements with time.
* Relative insensitivity to the flow rate and temperature of emissions.
* Relative insensitivity to water droplets.
Why the EP1000
The measurement principle of linear response to dust, results in precision over a wide range - the concentration of dust is proportional to laser beam backscattering. Pointed into the dust-bearing gas stream, the laser beam is scattered by the dust particles back towards the instrument, providing a signal directly proportional to dust concentration. Linear responses to dust concentration provide accurate emissions monitoring over a wide spectrum of dust concentrations. Requires only one isokinetic sample for accurate calibration. Cost of ownership is kept down, as the device requires very little maintenance.
Readings do not drift and the measurement technology adapts well to large diameter stacks found on power plants. Very long measurement path (up to 10 m), vibration sensitivity is not a problem. A standard display keyboard permits the user to view measurements and internal instrument parameters and perform the instrument set-up; remote display keyboards are also available as an option. (COMM1000 software is now available.)
With its Class 3A laser operating at a wavelength of 660 nm, average power of 1 mW, the instrument demonstrates an accuracy better than 2%, with a linearity better than 0,5%. There is a relay and an indicator light to highlight an alarm condition. The stack monitor is suitable for monitoring of filter efficiency, stack emissions, etc. The EP1000 has TUV certification and complies with EPA regulations. The sole agent for Oldham France, Spero Group is proud to represent this company.
