Measuring system
Measuring principle A reed resistor chain that is magnetically actuated by a magnetic
float in the BM 26 measuring chamber
Primary measured value Resistance
Secondary measured value Level and volume of the liquid in the measuring chamber
Design
Description of device Resistance reed chain with 2-wire loop-powered transmitter module
attached adjacent to the measuring chamber of the bypass level
indicator. Changes in resistance are converted to an output signal via
a transmitter module.
Description of transmitter
module
Changes in resistance are
converted to analog current
signals.
Changes in resistance are
converted to analog or digital
current signals. Up to 15
transmitters can be connected to
a network that agrees with the
HART® communication protocol.
Options Converter position - The customer must specify the position of the
converter at the top or the bottom of the analog transmitter
