◈ Application
• Ballast tank remote reading
• Draft remote reading
• Fuel oil tank remote reading
• Wast waters, wells, locks, rivers etc.
◈ Features and Benefits
With is high electrical and mechanical stability, pressure transmitter fulfills all plant construction standards.
• Ceramic measuring cell-extrimely resistant
to overload, alternating loads and aggressive
media.
• Support cable with hard-wearing conical seal
on the probe tube and climatic protection in
the pressure compensation tube.
• Potted electronics with 4~20mA output signal
and integrated overvotage protection.
• Certified for hazardous area EEx ia. |
|
◈ Operating Principle
The ceramic measuring cell is oil-free, i.e.the process pressure acts directly on the
rugged ceramic diaphragm of pressure transmitter and causes it to move by a max, 0.025mm.
A pressure-dependent change in capacitance is measured by the electrodes in both the
ceramic substrate and the diaphragm.
The measuring range is determinded by the thickness of this ceramic diaphragm.
