Differential pressure transmitter

Relative and diﬀerential
pressure transmitter
Type 699
The type 699 transmitters are available in switchable pressure
ranges and with or without display. The full-version includes
customer specific adjustment possibilities. Especially developed
sensors for each pressure range ensure accurate long term
stable measurement and the large variety of options provide theperfect platform for use in air conditioning technology as well as
for fine measurement in the industrial and medical environment.

Pressure range-1 ... 1 mbar /0 ... 0.3 – 50 mbar

+ Available with or without LCD display+ Adjustable measurement range+ Switchable output signals+ Switchable response curve (linear or root-extracted)+ Resettable Zero Point (Reset button)+ Full scale adjustable+ Attractive price / performance ratio+ Application at over and low pressure range possible+ Fast, easy mounting. Housing incorporates integral bracket
for wall or ceiling mounting
