Series 35 X HTC - 1

+ KELLERHigh Temperature Pressure Transmitter Serie 35 X HTCfor biotechnology / food-industries This piezoresistive high temperature transmitter 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, allowing media temperatures of up to 300 °C. The temperature of the electronics, which can be read out with the PROG30 software, may not exceed 120 °C. For highly aggressive media, KELLER offers pressure ports in different materials. Digital Output of Transmitter 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. Transmitter with Analog Output The micro-processor integrates a D/A converter of 16 bit for analog signal outputs of 4...20 mA or 0.10 V. The output rate is 100 Hz (adjustable). The digital output is available on all transmitters with analog output. Programming With the KELLER software READ30 and PROG30, 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.
