Catalyst Monitoring System

PTI has developed a RICE NESHAP compliant catalyst monitoring system which is able to monitor and record exhaust temperature entering the catalyst as well as the pressure drop across the catalyst. 1/8” NPT ports located upstream and downstream measure pressure drop across the catalyst while a single ½” NPT port upstream of the catalyst measures exhaust temperature. Both differential pressure and exhaust temperature are shown on the display screen as well as recorded on a microSD memory card at a user specified interval. Warning lights indicate if exhaust temperature or differential pressure is out of the ranges provided by the user.

Programmable Logic Controller (PLC) which is easy to use with the given tactile keyboard and display screen. Normal operating temperature, pressure drop and tolerances for warning lights set by user providing versatility to each application. Amber warning light to indicate an exhaust inlet temperature or differential pressure which is not yet out of tolerance but should be evaluated as soon as possible. The EPA recommends an inlet temperature between 450° and 1,350°F and a pressure drop of less than 2 in-H2O due to clogging of catalyst from use. Red warning light to indicate an exhaust inlet temperature or differential pressure which exceeds the maximum or minimum allowable value and should be addressed immediately. High-temperature thermocouple capable of maintaining a minimum tolerance of 5°F (2.8°C). Option of mounting differential pressure transmitter on left or right side of enclosure for convenient application to existing or new systems. 2 GB microSD memory card capable of recording years of logged data.
