FS-380 Flow Switch for X-ray Machine Coolant Flow
July 29, 2021
X-ray machines are vital tools for medical personnel to help properly diagnose and treat patients. X-ray machines have become more sophisticated, with additional features and options, through the incorporation of high-power electronics. With these added electronics, heat is generated inside the machines, and this excessive heat can lead to shortened equipment lifetime or even premature failure.
To dissipate heat from the machine, X-ray manufacturers run a coolant loop around the electrical equipment, containing either a glycol-based coolant or an oil-based coolant. Monitoring this coolant is crucial, as it requires a constant flow to effectively remove heat from the machine and transfer it elsewhere.
Challenge
Finding a reliable flow switch that can detect low flow rates and has a low pressure drop.
Coolant liquid is critical in many applications, and X-ray machines are no different. Medical equipment is expected to have a very high uptime and perform with high reliability. Having a piece of medical equipment break down during use is frustrating for both the operator and the patient who is using it. Uptime is the most critical characteristic that the solution must exhibit.
Solution
Gems Sensors FS-380 Flow Switch
The FS-380 is an inline design flow switch that reduces high-pressure drops. This is crucial for coolant liquid as the flow rate needs to be consistent and at a substantial rate to pull the heat away from the sensitive electronics within the X-ray machine. The piston-based design of the FS-380 flow switch is a simple yet reliable design with excellent repeatability. This piston and reed switch design is also not affected by the x-rays like other more sensitive electronic-based sensors.
Additional Benefits
- With setpoints as low as 0.15 gallons per minute, it can detect very low flow rates and still sense loss of flow
- With either a 316 stainless-steel or Brass body, it is a rugged flow switch
- Available in multiple different port sizes and types including 1/2", 3/8” NPT, 1/4", 3/8” Compression, and 1/2" Barb.
- Operating temperature range of -20°F to +275°F it can withstand extreme media conditions.
