When your organization relies on a cleanroom for daily operation, it's vital that you ensure that space remain completely uncontaminated from one day to the next. But your standard operating procedures for cleanroom management will only take you so far if you're not using proper sensors to ensure the space's cleanliness. Why do sensors matter if you're taking the proper steps to keep your cleanroom uncontaminated? Keep reading to find out.
Your cleanroom does not exist in a complete vacuum. You're likely pumping heated or air conditioned air into the space both day and night. It's important to have airflow sensors to monitor the movement of air into the room. You can set these devices to alert you when relative airflow reaches a certain threshold. This helps to maintain the ideal environmental conditions for your cleanroom.
Vibration sensors can be used in a few different ways in a cleanroom. First, you can mount them on equipment to detect any changes in the vibrations the machine creates. Typically, an increase in vibration is an early indicator of potential malfunction in the future. You can also mount them on your HVAC system to perform the same function; an increased vibration in your HVAC's system can indicate an issue. Early awareness of potential problems can help you to get needed repairs before a malfunction occurs, which could cause sudden changes in environmental conditions that may impact the cleanroom's purpose and functionality.
Temperature and Humidity
Cleanrooms need more than simple cleanliness to function as they should. Whatever experiments you might be running or chemicals you may be handling, the room must remain within a certain temperature and humidity range to avoid impacting your work. Temperature and humidity sensors will alert you to changes in temperature and humidity that could potentially impact the work you're performing in the cleanroom. They can also log data regarding these environmental factors, so that you can take them into consideration when analyzing the results of your work.
Many cleanrooms have a secondary space used for decontamination and pressurization as people enter or leave the space; this is essential to avoid contamination. When a door is opened without the adjoining space being properly pressurized, it can create a vacuum, which can cause air to pull dust and other pollutants into the cleanroom. Differential pressure sensors can measure the air pressure in two separate areas of the cleanroom, and indicate whether or not there is a difference in the readings.
These can also be mounted on ducts to alert you to sudden air pressure changes related to the HVAC system. They monitor both positive and negative pressure, and can send live data and readings so that you are aware of any changes in the cleanroom's environment.
Proper cleanroom management
involves far more than simply decontaminating staff members as they enter and leave the space. It even goes beyond using specialized gear and clothing, like hazmat suits, to prevent contamination. Properly managing your cleanroom means being constantly aware of potential contaminants, and maintaining a consistent environment to ensure that nothing interferes with your work or the material you're using in your cleanroom. And that means using the right sensors at every minute of the day. Check out Atlantic Technical System’s online store to see what sensors and other cleanroom equipment we offer.
