방폭형 압력변환기

Series 33X Ei / 35 X Ei / 36XW Ei / PD-33X Ei (압력변환기)

Highly Precise Pressure Transmitters
Series 33 X Ei, 35 X Ei, 36 XW Ei, PD-33 X Ei

For Hazardous Applications

These pressure transmitters are all ATEX approved for use in Hazardous Areas where there is a high risk of explosion.

Digital Output of Transmitter : *
These Series are based on the stable, floating piezoresisitive transducer and a micro-processor with integrated 16 bit A/D converter. Temperature dependencies and non-linearities of the sensor are mathematically compensated. With the READ 30 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:
Integrated in the processor is a D/A converter of 16 bit for analog signal outputs of 4…20 mA or 0…10 V. The output rate is 400 Hz resp. 100 Hz (adjustable). The accuracy is diminished by this converting process by 0,05 %FS. The digital output is also available on analog transmitters with cable connection.
