Meters and sensors

Introduction
Sensors that measure pressure, conductivity, temperature, pH, flow and UV are
included in the ÄKTA readyflux flow kits. The sensors are disposable and intended for
single use only. They are pre-calibrated.
The sensors are connected to meter units inside the instrument cabinet. The sensors
must be connected to the meters via connector cables.
Pressure sensors
ÄKTA readyflux flow kits have three pressure cells that can measure the pressure of the
liquid continuously:

PT-111
PT-112
PT-113
The locations of the pressure sensors are also depicted in
Flow sensor
ÄKTA readyflux flow kit contains an ultrasonic flow sensor (transducer) FE-141 that
measures the flow in the permeate flow path.
Conductivity and temperature
sensors
ÄKTA readyflux flow kits contain two sensors that measure the conductivity and
temperature of the fluid during a run. The temperature sensors measure the tempera-
ture by measuring the electrical resistance of metal electrodes and is a part of the
conductivity sensor.
