MAC155 Moisture Analyzer

For CONTINUOUS STACK MONITORING With BUILT IN TWO POINT CALIBRATION

Measure % Moisture By Volume In Exhaust Gasses At Temperatures up to 1200°F
Optional to 2400°F
Two Models Available
MAC155-LT covers 3% to 15% or 6% to 30% ranges (user selectable)
MAC155-HT covers 3% to 15%, 6% to 30%, 9% to 45%, or 12% to 60% ranges (user selectable)
NEMA 4X Waterproof Design
Suitable for outdoor installation
Contains Built In Equipment Allowing Daily 2 Point Calibration Check
Sensor is flooded with an internally generated reference gas of specific moisture levels
Can Be Re-Calibrated In the Field Using Internal Calibrator
System Calibration
Sensor signal substitution can be externally initiated to generate an ouput signal 50% of full output.
From the MAC155 Controller, 3 different output signals can be generated.
Provides a method of checking total system includingdata aquisition equipment.
Patented Measurement Process
In Situ Measurement
Mounts directly to stacks or ducts
0-20mA or 4-20mA Signal Output User selectable
Self powered or loop powered (jumper selectable)
Filter Blow Back Option
Allows automatic filter cleaning (requires 10 psi clean dry air)
Case Heater Option
Extend ambient temperature rating to -40°F

The MAC 155 In Situ Moisture Analyzer is designed to continuously monitor emission stack gases.
It is designed to meet EPA and local regulatory requirements for stack gas moisture measurements.
The patented solid state design has been proven in hundreds of industrial process control applications.
The moisture sensor is extremely rugged and requires no chemicals, compressed air, optics or mirrors.
The % moisture by volume is measured using a proprietary high temperature capacitive sensor that responds
to water vapor pressure in the presence of other gasses.
The MAC155 Moisture Analyzer is provided with automatic two point calibration check at user selectable moisture levels. The on board calibration system can challenge the sensor with a controlled water vapor sample. An internal tank holds enough water to generate vapor samples for one year of daily calibration checks.
