What is PID Gas Detector?
PID stands for Photo Ionization Detection, and a PID gas detector is a device used to measure the presence of volatile compounds. These compounds are gases that have significant vapor pressure and pose a severe threat to our health and environmental settings. Detection of volatile compounds is also necessary because these gases have a slow symptom and long-term effects.
How does it work?
PID detectors are widely used in industries that deal with paints or adhesives or work in confined spaces. These devices perform well when you collaborate them with the ventilation systems to ensure proper air passage as well as gas emission detection. These detectors work with ultraviolet rays that ionize the molecules passing that excites them and cause them to lose electrons. Once they lose electrons, they become negatively or positively charged and generate electric current. A stronger current means a strong presence of volatile compounds. To ensure the effectiveness of detected reading, PID calibration gas equipment is necessary, as they will detect compounds even at a deficient concentration. Regular calibrations mean that the readings will be accurate and is a reason that makes PID devices highly preferred in a hazardous environment.
Key Advantages of PID Detectors
- PID gas detectors can detect volatile gases at a very low pressure that makes it invaluable in case of the emergency leak since volatile gases are combustible, even at lower pressures. Any industrial facility that works with organic materials must consider having PID devices. Natural materials include gasoline, kerosene, propane, paint, thinners, jet fuel, polish removers, and diesel. All these materials quickly catch fire and are hazardous for the environment, so to prevent accidents; PID is a necessary device to use. However, unless you combine the PID with other tools like multi-gas meter, it cannot detect natural gas.
- PID detectors can prevent major mishaps if appropriately used. In the case when the calibrated gas is different from the on-location gas, the reading displayed will be inaccurate. PID on itself cannot detect any volatile gas but only the level of gas present. To name the chemical, PID needs pairing with other devices and technologies. For industrial safety and maximum accurate detection, wireless gas monitoring systems along with PID is the best combination
Is PID Necessary?
Detection and prevention of unknown gas emissions are a necessity for every industry and with the sensory technology continues to evolve, workers in confined spaces offer better protection against emitted gases. PID gas detectors are now playing a vital role in ensuring worker safety as well as environmental sustainability.
Considerations before Purchase
- Assess your risk factors before considering the purchase of any PID device. Businesses that involve working with volatile gases and compounds must assess the dangers involved. Hazards that can cause damage to health or the environment is necessary before finalizing the decision to buy a device
- Center your objective according to the detection of compounds, whether it is about notification or reporting. Selection of objective mean centering your device decision according to health and safety standards
- Understand the features of a device before purchasing as different devices have specific functions. Comparing the characteristics of various PID detectors is the best way of determining which equipment is suitable for your settings. Determine whether the kit you choose has a feature that aligns with your objectives and make a decision accordingly
- Consider environmental conditions that can affect the working and functions of a device like a temperature, humidity, air pressure, day and night variations, fluctuations, etc.
- Always communicate the needs, risks, and hazards clearly as the lives of your workers and your business depends on it. Assessing and monitoring the type of volatile compounds present is necessary to communicate the risks and select a device accordingly. Communication is also essential to choose an alarm system needed for prompt notification in case any hazard is detected
- Always select a device that has a natural feature and a friendly layout. No one wants to remain a risk while figuring out how to work a PID detector. Simple design, ease of access, and user-friendly layout is a necessary point of a suitable device. Besides ease of access, it should also possess accessible maintenance features
