The Keller 25 HTC Pressure Transmitter is a piezoresistive high temperature transmitter (-transducer) is suited for media temperatures
up to 572°F (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 572°F (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, pressure ports are offered in different materials.
