A novel pressure sensor comes with a guaranteed stability of 0.25% per year at 150C.
A novel pressure sensor comes with a guaranteed stability of 0.25% per year at 150C.
This is achieved by using inorganic "gauge-on-glass" technology to achieve high stability at high temperatures.
The sensor is capable of working up to 250C and more.
The one-piece pressure port and sensing diaphragm do not have O-rings or welds, and so the hysteresis and nonrepeatability are low.
Combining this with "gauge-on-glass" technology produces a very stable sensor with an accuracy of 0.5%.
The pressure port can be made from 316L stainless steel, Inconel, Hastalloy or titanium to make the sensor useable with a variety of noxious fluids and gases.
The model GC sensor from Control Transducers has a ratiometric output of 100mV at 10V excitation and is available in 10 pressure ranges from 0-1.7 to 0-690bar.
It is suitable for use in many diverse applications from refrigeration controls to ink-jet printers, and OEMs will find its low cost attractive.
The fully welded case is sealed to IP66 (waterjet-proof) and so it is suitable for outside installation and hosedown applications.
