Additional Solutions From Servoflo’s Mass Flow Sensors

Posted by David Ezekiel on Feb 6, 2020 9:28:14 AM

Companies across a range of different industries use mass flow sensing technologies to meet specific application requirements in a variety of applications. Here, the team at Servoflo provides a few examples of the advantages of mass flow sensors in machines and mechanisms being designed today.

Solutions for Servoflo’s FS6122 Bi-Directional Medical Respiratory Sensor

In the medical industry, mass flow sensors play a key role in the functionality of respiratory monitoring equipment, such as CPAP or anesthesia delivery systems and other types of medical equipment. For example, the Servoflo FS6122 Bi-Directional Medical Respiratory Sensor has been especially designed for suitability in medical applications. It is an energy-saving, fast-responding sensor that can measure mass flow rate in the range of -250 to 250 SLPM (standard litres per minute). This bi-directional sensor also has a unique additional feature of an optional humidity sensor, giving users even more environmental measurement capability.

Some typical flow sensor applications in the medical industry include:

· Air mattresses and cushions

· Anesthesia equipment

· Asthma detection products

· Biological chamber air circulation devices

· Drug delivery solutions

· Endoscopes

· Gamma knives

· Infusion pumps

· Oxygen concentrators and conservers

· Other oxygen therapy tools

· Respirator and breath detection machines (especially for cases of sleep apnea)

· Smart oxygen homecare cylinders

· Spirometers

· Veterinary machines and tools

Solutions for Servoflo’s FS5001B MEMS Mass Flow Sensor

Other mass flow sensors from Servoflo have exceptional operational capabilities for industrial and electrical applications, among many others. For instance, the FS5001B MEMS Mass Flow Sensor has the following key attributes:

· An effective operational range anywhere from 0 to 200 SCCM (standard cubic centimeters per minutes) up to 0-1000 SCCM

· An exceptionally quick response time of 10 milliseconds

· A pressure rating that can go up to 5 bar (72 psi)

· A small form factor of 48.5 x 48.5 x 18.5 mm

· Accurate readings within a range of ±2.0%, in addition to a ±0.5% range for full scale readings

· Outputs that include linear analog from 0.5 to 4.5 volts, digital RS232, or I2C

Additional Applications of Mass Flow Sensors

Mass flow sensors are highly versatile. For instance, most car engines use mass air flow sensors to inject the correct mix of fuel and air into the engine’s combustion chambers. Mass flow sensors also allow welders that use oxy-fuel equipment to work safely.

The following list includes several examples of common use cases for mass flow sensors:

· Medical: specifically the FS6122 Bi-Directional Medical Respiratory Sensor

· Electronics

· HVAC Engineering: particularly for variable air volume (or VAV) systems, cleanroom management, and refrigerant monitoring

· Industrial: for use in process gas monitors, gas mixing solutions, and welding gas controls, among many other applications

· Food and Beverage: for oven flow monitors, food freshening solutions, and even food packaging

The Most Common Mistake Made When Selecting A Pressure Sensor

Posted by David Ezekiel on Sep 26, 2012 11:52:00 AM

sample pressure sensorSelecting a pressure sensor for your application sounds simple, but with the huge amount and range of performance options, it's easy to get overwhelmed with what the best model is for your application.

We have seen situations where designers choose the most expensive and most accurate part for their needs at the beginning of the design. It's the path of least resistance. However, once production arrives and cost reduction is required, most especially for high volume applications, the established, set-in-stone design specification does not allow for a lower cost option without sacrificing performance. The engineer is stuck or needs to initiate a costly redesign.

To prevent this situation from occurring, we suggest starting with the widest tolerance (and hence lower cost) pressure sensor. Through your testing and evaluation phase, you may find that the lower tolerance models can work. In particular, if you have the ability to provide your own calibration or additional signal conditioning, you may discover that an acceptable specification is met. Furthermore and most importantly, it is significantly easier to move up the price/performance chain than going down it. Flexibility is designed in should performance requirements tighten in the future.

Once the target accuracy is determined for a product, designers should then look at sensor options in conjunction with their ability to add value (such as calibration, temperature compensation, signal conditioning). This is the classic make versus buy question which must be asked. We can help with the answer!
