COMPACT PRESSURE SENSOR
DATA SHEET
FCK
The compact pressure sensor measures the pressure or
absolute pressure of liquids, gases or steam, and outputs a
current signal.
A compact and simple structure procures high reliability
and long-term stability. The instrument can be mounted on
any of general industrial facilities, and is best suited for au-
tomation, labor-saving, efficient operation, etc. of equipment.
FEATURES
1. Compact and simple structure facilitating an installation
The structure is compact, lightweight and simple. Mount-
ing is easy with direct screwing-in requiring no fixtures.
2. Abundant range of products
Pressure sensors and absolute pressure sensors are avail-
able. Current output is usable. The pressure measuring
range includes very low to high pressure. All these fea-
tures destine the instruments to different applications.
3. Coping with environmental conditions
The dust and water-proof structure complies with IEC IP65.
