The P5: A Versatile PM-CEM
The P5 is a sensitive and reliable CEM for measuring particulates in a flowing gas in stacks and ducts. It provides the user with CONTINUOUS, IN-SITU measurements of mass concentration and is very useful for the following applications
Þ process optimization e.g. checking and diagnosing boiler firing to maximize fuel utilization and minimize particulate emissions
Þ compliance monitoring to meet an emission permit e.g. to provide a continuous readout in the control room to enable the operators to keep the process in compliance at all times.
Þ air pollution control: the P5 provides a 4 - 20 MA output to an APC device for automatic emission control e.g. the P5 output steers the precipitator's fields to maintain compliance.
Þ The P5 was developed by Environmental Systems Corporation in the late 1970's.
Þ Uses the principle of light back scattering and is a single ended unit i.e. there are no mirrors or alignment requirements
Þ Measures particulate mass concentration in mg/actual cubic meter.
Þ Using stack test data a linear coefficient can be developed that converts mass concentration in actual units to dry standard units as used in permits.
Þ Provides a linear response to particles in the size range 0.1 to 5 microns
Þ The P5 has been tested and verified to duplicate EPA Method 5 within the tolerances specified in ISO 10155 and EPA preliminary monitor spec PS-11
Þ Has a measurement range of 1 to 20,000 mg/actual cubic meter
Þ Available with standard probe lengths of 18", 36" and 60". Custom lengths are also available.
Þ It is a rugged, modular design with easy access to all its working parts
Þ The sensor probe is air cooled using a built-in blower with 2 stage filter
Þ Installs on the side of the stack or duct by means of a 4" ANSI 150# flange
Þ Requires minimal maintenance: only periodic replacement of the air filter
Þ Large installed user base, many with multiple units
Þ 2 models available:
Þ P5A has analog electronics and manual calibration
Þ P5B has digital electronics with automatic features such as calibration and fail-safe, etc
Þ The P5A gives the same accuracy as the P5B but is a less expensive version
