Page 2: General Precautions
1. General Precautions The system must be used only in accordance with the required protection level. The sensor must be protected against accidental knocks and used in accordance with the instrument’s ambient characteristics and per- formance levels. Sensors must be powered with non distributed networks. For outdoor installations or with cables longer than 30 m*, proceed as indicated at paragraph 3. -

The response time to the pressure transduction is equal to 1 ms Indications and alarms The KS Series pressure sensors in the case of some specific anomalies provide output saturation (positive HIGH or negative LOW). The table 1 indicates the detected failures, their effect on the electrical output, and the recovery mode of the device. - Page 7 Applications to use the relevant category The pressure sensors of KS Series may form part of a system for detecting the pressure that, when a threshold value is exceeded, deactivates all the elements of pressure generation, through a control system.
