Product Details
Sanitary Application Smart Electronic Digital Pressure Switch For
Industrial Process Control
Description
The pressure switch SPS is designed for pressure monitoring and
measure-ment in liquid and gaseous media. The SPS is suited for
general industrial applications such as machine and plant
engineering, in machine tool systems, in hydraulic and pneumatic
systems, for pressure monitoring and control and for pumps and
compressors. It is pressure switch, transmitter and display in one
and the same device. In its standard configuration it has two
switching outputs (PNP or NPN). In addition, there are
configurations available with an analog output signal (0...20mA|
420 mA or 0...5V| 0...10 V) as well as with RS485 Link
Applications
Gas-liquid dual-capable can be used in : pump control, storage tank
monitor, liquid level control, filter blocking and monitor, leakage
surveillance.
Industrial process testing and control
Self-controlled and constant-pressured water supply in building
Petrochemical, environmental protection, water conservancy, light
industry, machinery, metallurgy
Measuring and control in other systems
