PS11 Pressure Sensor in X-Ray Machine Cooling Loops
Jun 8, 2021
As X-ray machines become increasingly sophisticated, manufacturers are incorporating high-power electronics to enhance the machines' capabilities and add extra features and options. With these added electronics, heat is generated inside the machines. Excessive heat can lead to short equipment lifetime or even premature failure.
To overcome this heat, X-ray manufacturers run a coolant loop around the electrical equipment containing either a glycol-based coolant or even an oil-based coolant. Monitoring this coolant is challenging because it is usually running at low pressures (under 15 psi / 1 bar), and OEMs require very accurate set points to ensure that cooling is under control.
Challenge
Finding a reliable pressure switch that is capable of accurate low switching capabilities and long life-time expectancies.
When dealing with medical equipment, including X-ray machines, they are typically installed for extended periods and must be highly reliable. Having a piece of medical equipment break down during use is frustrating to the operator and even more frustrating to the patient to whom this equipment is being used! Uptime is the most critical characteristic that the solution must exhibit.
Solution
PS11 Low-Pressure Switch
The PS11 features a wide variety of elastomer and film diaphragms (to ensure wide media compatibility), long-life internal microswitch (that has proven to be accurate even after 2 million switch cycles), as well as a large diaphragm (that ensures the switch has accurate low-pressure set points)
