Pressure Transmitters high temperature 150°C
Serie 35 X HT

Piezoresistive pressure transmitter for applications in bio-reactors or autoclaves.
The transmitter is compensated up to 150°C and may be operated continuously or sterilised
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.
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 nonlinearities of the sensor are mathematically compensated. With the READ30 software and
the RIELS 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 C. 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 accuracy is diminished by this converting process by 0,05 %FS.
The digital output is available on all transmitters with analog output.
Programming
With the RIELS software READ30 and PROG 30, a RS485 converter (i.e. K-102, K-104 or
K-107 from RIELS) 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.
