Guide for Establishing Relative Humidity Levels in Operating Rooms

Successful surgery depends not only on the performance of medical professionals, but also on the integrity of the environment. Relative humidity is a critical component in maintaining the safety and performance of an operating room (OR).

How Often Should I Calibrate A Pressure Transducer?

Transducers are used across many applications to provide accurate, real-time data of how a system is working. Calibration is critical to maintaining a pressure transducer’s accuracy and it is not a one-time process. All pressure transducers used in critical applications should be regularly calibrated to maintain high performance. If a transducer drifts out of its specified pressure range, it can lead to false pressure readings causing decreased equipment performance and possible safety concerns. Calibration allows the user to be completely confident that their transducers are correctly performing and measuring the required pressure range accurately.

So, how often should you calibrate a pressure transducer? It is a common question we get asked all the time. Pressure transducers should be calibrated as often as needed in order to, maintain the necessary accuracy for the application. The amount of calibration required by the transducer can vary based on factors, such as the application and the transducer’s stability

What Can Affect A Sensor’s Accuracy?

Selecting the correct accuracy for your sensing application is only half the challenge; being able to maintain that level of accuracy over time is equally important. To clarify on what we mean by the accuracy, we define it as the maximum difference between the actual value and the sensor’s output (in terms of %FS).  Maintaining a sensor’s accuracy is difficult. Users face the issue of a sensor going out of tolerance and are unaware of the root causes. Depending on the level of accuracy required by the application, the consequences of imprecise accuracy can vary. For example, an isolation room requires a high level of accuracy to protect both the patients’ and medical professionals’ health and safety. If a room pressure monitor provided doctors and nurses with an incorrect sensor output, they can make incorrect judgments such as walking into a improperly labeled space. Based off of the inaccurate sensor output, doctors and nurses can also accidently release harmful contaminants into the rest of the hospital without a proper alarm notification.

What Causes Sick Building Syndrome?

After understanding the basis of sick building syndrome, recognizing the root causes for the syndrome is the next step for prevention or treatment. By properly identifying the root causes, suitable countermeasures can be constructed.  Causes for sick building syndrome can be classified into three categories:

What is the difference between energy consumption and demand?

In order to understand your electric bill, there are two main concepts you should understand; energy consumption and demand. These charges are regularly misunderstood, making it difficult to prioritize which energy savings measure will have the biggest impact. People are often overcharged by their energy provider or have failed to reduce their total energy cost due to a lack of understanding or improper calculations.

What are the Benefits of Field Replaceable Tips?

When selecting a humidity sensor, we recommend choosing one with a field replaceable tip. Why are we recommending this? A field replaceable tip is easy to replace and allows the end-user to swap the sensor on-site without having to calibrate the unit or remove it from its mount. We recommend sensors with field replaceable tips for the following reasons:

What is Measurement Traceability?

Pressure sensors are used across a variety of industries to provide accurate, real-time data of how a process or system is operating in a given application. But how can you tell if your data is accurate? The most common method to ensure the accuracy of a sensor output is to calibrate your sensor against a higher accuracy pressure sensor (calibration standard). Now, how can you tell if your calibration standard is accurate?  This is where measurement traceability plays into the calibration process.

Where should I Mount a Wall, Duct or Outside Air Relative Humidity Sensor?

As we have talked about in our Importance of Measuring Humidity post, accurate humidity measurement is crucial.  Building owners must be sure to maintain and monitor humidity levels for occupants' comfort and safety. Improper humidity measurement can put a building at risk for mold and other airborne pathogens which can lead to sick building syndrome.

There are three types of mounts for humidity sensors; wall mount, duct mount or outdoor air. In order to operate correctly with a long life expectancy, it is vital that the sensor is properly mounted and placed. Proper mounting requires careful consideration to ensure the sensor meets your needs. Here is a guide on how to place three types of humidity sensors:

Can A Room Pressure Monitor Help Me Save Energy?

Monitoring and controlling room pressure in laboratory and healthcare settings can do more than just ensure directional airflow (positive or negative pressure rooms). Proper room pressure also contributes to saving energy. Overpressure or under-pressure scenarios mean that airflow, or even temperature control, are not optimal.
