Water level / well probe /
Tank contents meas. probe

Description:
Piezo-resistive pressure sensor with temperature compensation.
Welded, non-corrosive design with integral and additionally sealed
water-proof connecting cable.
The pressure compensation is done via a a cable-integrated air path to the
atmosphere. Possible cable length up to 300m. A special feature is the
lateral flow resistanc, which prevents media ingress. Therefore only the
cable has to be replaced in case of a corresponding defect, while the
sensor is still unharmed.
Please specify cable length (up to max. of 500 m) when ordering. |
|
GBS 01
|
For simple and inexpensive applications. Suitable for
permanent level measuring in tanks, rivers, lakes, drinking-water wells,
drillling holes, waste water plants.... |
GBS 02
|
For measuring the level of fuel and other aggressive media.
The sensor is highly precise, insentitve to lateral flow and offers
optionally lightning protection and other output signals (e.g. 0-10V). For
measuring of gasoline please order EX-protection. |
