2.1 Probes and sensors
Table 2.1 lists the sensors most frequently used with the Silometer FMC 672 Z/677 Z
transmitter. In addition to those listed, all special probes which can be used with an
EC 37 Z or EC 47 Z electronic insert can be connected to the transmitter. Installation
hints can be taken from the appropriate Technical Information Sheet.
Sensor contants EC 37 Z/47 Z inserts are supplied with the sensor constants zero frequency »f
o
« and
sensitivity»S« printed on the name plate. Note these constants and enter them into fields
V3H5/V3H6 and V7H5/V7H6 during commissioning, Section 4.1. This dispenses with the
need for a recalibration of the transmitter on replacement of the sensor or insert.
