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.

The micro-processor integrates a D/A converter of 16 bit for analog signal outputs of 4-20 mA or 0 to 10 V. The output rate is 100 Hz (adjustable). The accuracy is diminished by this converting process by 0.05 %FS. The digital output is available on all transmitters with analog output.

With the KELLER software READ30 and PROG 30, a RS485 converter (i.e. K-102, K-104 or K-107 from KELLER) and a PC, the pressure can be displayed, the units changed, a new gain or zero set. The analog output can be set to any range within the compensated range.
