|Optrand Extends Maximum Temperature Rating of Its Pressure Sensors to 450°C
Optrand pressure sensors are now rated for operation at temperatures up
to 450°C (840°F) without cooling.
Benefitting from a metal coated optical fiber and ultra-high temperature
glass seal, the sensor head (process connection) of Optrand’s pressure
sensor can be exposed for thousands of hours to temperatures as high as
450°C without cooling. Such capability is available even for subminiature
devices 1.8mm in diameter. Furthermore, the 450°C-rated sensors can measure
very small or very large pressures, ranging from 0-1 bar up to 0-3000 bar.
Unlike alternative high temperature piezoelectric or piezo-resistive pressure
sensors which can be exposed to maximum temperatures only at their front
surfaces, the entire sensor head and even a part of the cable of the Optrand
sensor can be exposed to 450°C.
These sensors can continuously measure dynamic pressure or both static
and dynamic pressurecomponents intermittently. The ultra-high temperature
capability is not associated with anincreased signal noise observed in
the alternative pressure sensors. Finally, Optrand’s 450°Crated sensors
cost a fraction of the competing piezoelectric dynamic or piezoresistive
“The new enhanced capability to measure pressure without cooling at temperatures
up to 450°C for thousands of hours enables a wide range of applications
previously not available to our sensors” says Dr. Marek T. Wlodarczyk,
Optrand’s President & CEO. “A few examples include
pressure measurement of plastic melts requiring sub-miniature sensors,
monitoring and control of stationary and aviation turbines, measurement
of engine exhaust pressure, and tuning of Formula One and other racing
