Relative and differential
pressure module type 698
Pressure range
-5 ... 5 mbar / 0 ... 1
10000 mbar
The pressure modules type 698 are suitable for monitoring
pressure and flow in air conditioning systems and in the
laboratory sector.
The module is optionally available with a 3 digit LED display,
two limit value switches (potential free) as well as a square
root extraction.
Rugged measured value detector, owing to
outstanding synergy obtained by combining
diaphragm technology with a cermaic element
High overpressure safety margin, even in
the lowest pressure range
Easy to install and commission
No maintenance required
High Protection standard
