Description
The Keller 35X HT / 35X HTT Pressure Transmitters are piezoresistive pressure transmitters for applications in bio-reactors or autoclaves. The transmitters are compensated up to 302°F (150°C) and may be operated continuously or sterilized at this level, including the special circuit electronics. The transmitters are supplied in absolute or gauge versions, with current or voltage output. The sensing component is a micro-machined silicon pressure chip of high sensitivity. An independent temperature sensor is integrated on the surface of the silicon chip.
These Series are based on the stable, piezoresisitive transducer and a micro-processor electronics with integrated 16 bit A/D converter. Temperature dependencies and non-linearities of the sensor are mathematically compensated. With the READ30 software and the KELLER cable K-107, the calculated pressure can be displayed on a Palmtop, Laptop or PC. The READ30 software also allows the recording of pressure signals and the graphic display on the PC. Up to 128 transmitters can be hooked together to a Bus-system.
