APPLICATIONS
APPLICATION
Interstitial pressure sensor EP1 ae used to measure the fluid Weight (without cable)
pressure existing in all fields. 2 000 g
It is principally used in the monitoring of hydraulic structures
(dams, pipes ...), and where the water presence have a highly Filter permeability :

DESCRIPTIF ESCRIPTION
D Model 2PBK
The EP1 sensor is composed of bronze elements including a 2 pairs of conductors
cylindrical enclosure and a bellows diaphragm which ensure a Separate shield
perfect pressure transmission and increase the roughness of the Internal Kevlar rope (support)
sensor. Coil’s ohmic resistance :

The coming of the fluid in the diaphragm misshape it, modifying > 80 Ω
the tension of the vibrating wire which is connected to. The
calibration of each sensor permit to know the pressure for each
frequency read. Options :
The choice of the filter (ceramic or bronze) permit to Adaptation for installation
match/accord / match that element to the permeability of the on pipe
field in which the sensor is installed. Adaptation with packer for
The conception of the sensor take in count the temperature underground installation
compensation. So that reading with all referring calculation
became unnecessary. Accessories :
That apparatus, with its two electromagnets, use the sustained Switching box panel
mode reading principle on the vibrating wire, which gives it an Manual readout unit
unequalled accuracy, a long life-time, and permit a very long
distance signal transmission on these model of sensor.
