HIGH TEMPERATURE PRESSURE TRANSMITTER SERIES 25 HTC

FOR BIOTECHNOLOGY / FOOD-INDUSTRIES

This piezoresistive high temperature transmitter (-transducer) is suited for media temperatures
up to 300°C. The pressure, acting onto the flush diaphragm, is transferred over an oil-filled
capillary onto the silicon measuring cell. The capillary has the function of a cooling spiral.
When measuring media with temperatures of 300°C, the temperature at the silicon cell only
increases by 100°C. The integrated amplifier electronics provide a voltage- or current signal
proportional to the pressure.
For highly aggressive media, KELLER offers pressure ports in different materials.
