5 Rules of sensor placement in validation/mapping applications

This article expands upon 5 rules to apply when creating a rationale for sensor placement in mapping studies. Learn how to:

  1. Map the extremes
  2. Map in three dimensions
  3. Map large spaces
  4. Identify and address variables
  5. Relationship of mapping and monitoring

5 Frequently Asked Questions about Temperature and Humidity Validation Mapping

  1. What limits should I use as an acceptable range for my study?
  2. What type of sensor(s) should I use? 
  3. How many sensors do I need, and where should I place them?
  4. What kind of calibration do my sensors require?
  5. What is the appropriate duration for a mapping study? 

Validation Mapping

Vaisala DL1000-1400 is a high-accuracy temperature data logger. Ideal temperature logger for ultra-low temperature regulated environments.

DL1000-1400 Temperature Logger

Vaisala DL1000-1400 is a high-accuracy temperature data logger. Ideal for ultra-low temperature freezers, fridges, cold rooms in regulated environments, the DL1000-1400 temperature logger provides stable, reliable measurements.

Temperature Data Loggers DL1016/1416

Vaisala's multi-application temperature data logger monitors temperatures in up to four applications with one logger – ultra-low temperature freezers, freezer/refrigerators and incubators.

IQOQ Sample

The purpose of this IQ/OQ protocol is to provide assurance that the Vaisala vLog Data Logging and Reporting System has been set up properly, is functional, and operates with a high degree of integrity, security and reliability. The Installation Qualification (IQ) protocol template has been designed to ensure that the system, composed of both the hardware and the software, has been installed correctly at the point of use. The Operation Qualification (OQ) protocol template has been designed to ensure that each component of the system performs as intended.

Continuous Mapping: Better Data, Better Compliance

Mapping validation studies can be costly and time consuming. Have you ever wondered about leaving the mapping sensors in place and using this high-density sensor deployment for monitoring?  Essentially, this would result in ‘continuous mapping’ of the environment. Long-term data shows periodic excursions that a short-term, seasonal mapping study might miss. In addition, if a sensor failed or lost communication, full visibility of warehouse conditions would still be available. But, is continuous mapping cost prohibitive?

In this webinar, we analyze the actual costs of continuous mapping, as compared to intermittent mapping studies. The results might surprise you, but the data quality and increase in environmental control will definitely excite you.
