◊ Electric Pressure Transmitter Type
◈ 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.
