The company I work for wants to monitor the heat in a drying chamber remotely (between 85°F - 135°F). I am browsing your website looking for a sensor to monitor temperature and humidity. I am interested in more information regarding which environmental sensor will be best suited for my application, and I am hoping someone can give me some advice or direction moving forward.
The below are requirements and information/questions that I am looking for that must meet my business requirements:
The sensors must be calibrated by the manufacturer and there must be proof of calibration (calibration certificate) upon purchase of sensors.
Can the sensors be calibrated by a third party?
What is the recommended calibration interval (how often should the sensors be calibrated, yearly?)?
What is the calibration tolerance?
Can the sensors be remotely monitored utilizing my company’s software / platform?
Welcome to the DigiKey TechForum. Click here for the Humidity/Temperature Sensors we have available.
Usually for a device to include a Certificate of Calibration, it would have to be specially quoted/ordered to include the certificate. Some of these say they are pre-calibrated, but they will not have a certificate.
Maybe one of the Engineers can add to this post with their recommendations, and help with the specifics and design questions.
Thank you for your response, David! The drying chamber is about 604 square feet, and we currently have an external monitor mounted outside of the drying chamber, however, the initiative now is to install new sensors that can monitor the heat remotely, so I need to find a sensor that will enable this feature as well as the from my initial post. Any recommendations DigiKey can offer will be greatly appreciated!
The cost of traceable calibration certificates in low quantities can often raise a product price by a factor of 3 to 10, or more.
If you are manufacturing drying chambers, then it may be more profitable in the long run to operate your own traceable calibration lab, buy uncertified sensors and certify them in-house.
If you are just using a drying chamber, I strongly recommend contacting a specialist provider that can get the lowest price on certified systems and services for industry. I have known Omega Engineering for my whole 40+ year career and highly recommend their services.
