Frequently Asked Questions
Find answers to common questions about fixed gas detection systems, industrial gas detectors, installation, servicing and ongoing support.
What is a fixed gas detection system?
A fixed gas detection system continuously monitors an area for the presence of hazardous gases. Permanently installed gas detectors can provide early warning of toxic, flammable or oxygen-related hazards, helping protect personnel, equipment and industrial operations.
What gases can fixed gas detectors monitor?
Fixed gas detection systems can be configured to monitor a wide range of toxic and flammable gases, as well as oxygen levels. The correct detector and sensor technology depends on the gas hazard, application, environment and required measurement range.
Which industries use fixed gas detection systems?
Fixed gas detection is used across industries including food and beverage, manufacturing, wastewater treatment, battery storage, petrochemicals, mining, tunnelling, power generation and pulp and paper. Systems are selected around the specific hazards and operating conditions of each site.
Where should fixed gas detectors be installed?
Detector positioning depends on factors such as the gas being monitored, potential leak sources, ventilation, airflow, gas density and the layout of the site. Correct positioning is an important part of designing an effective fixed gas detection system.
Do fixed gas detectors require regular calibration?
Yes. Gas detection equipment requires appropriate testing, calibration and maintenance to help ensure accurate and reliable operation. The required frequency will depend on the equipment, application, environmental conditions and manufacturer recommendations.
What is the difference between fixed and portable gas detection?
Fixed gas detectors are permanently installed to provide continuous monitoring of defined areas or processes. Portable gas detectors are carried by personnel and provide mobile protection. Depending on the application, a site may use both fixed and portable gas detection equipment.
Can MTI help design a fixed gas detection system?
Yes. MTI can help identify suitable fixed gas detection equipment based on the gases present, application, operating environment and site requirements. This can include detector selection, system design and integration with associated monitoring and control equipment.
Does MTI provide installation and commissioning?
MTI provides fixed gas detection support through its experienced engineering team, including installation, commissioning and ongoing technical support. Requirements can be tailored to individual sites and gas detection systems.
Can existing gas detection systems be serviced?
MTI provides planned maintenance, calibration, functional testing and technical support for gas detection equipment. Existing systems can be assessed to establish the appropriate servicing and maintenance requirements.
How do I choose the right fixed gas detector?
The correct detector depends on the target gas, expected concentration, sensor technology, environmental conditions, area classification and how the detector will integrate with the wider safety system. MTI can help specify suitable equipment for your application.
