1.1 Application
The Silometer FMX 570 is designed for level measurement with a capacitance or
hydrostatic pressure probe in safe or explosion hazardous areas. It possesses an
intrinsically-safe sensor circuit conforming to EEx ia IIC and IIB. A list of certificated
combinations is to be found in »Notes on Safety« preceding this chapter. A working
system for level measurement comprises:
•Silometer FMX 570 transmitter,
•Capacitance, Multicap or Deltapilot S probe
•Electronic insert
Silometer function The capacitance or pressure measured by the sensor is converted into a frequency
signal by the electronic insert located in its head. The Silometer FMX 570 supplies the
power and receives a level-proportional frequency signal over a two-core cable. The
signal is then processed to provide a level or volume measurement.
Fail-safe operation If a fault condition is detected, e.g. a break in sensor - transmitter cable, the analogue
signal switches to -10 % or +110 % level or holds the last measured value. In addition,
the alarm relay de-energises.

1.2 Measuring principle
The Silometer FMX 570 measures level on the basis of the capacitance and hydrostatic
measurement principles. In both cases the measured value is processed by the
electronic insert and passed on as a frequency signal.
The probe and vessel form the two plates
of a capacitor, the total capacitance of
which can then be calculated from the
formula:
Ctot =C
1 + 2πε0εrx L pF (1)
--------------------------------
ln (D/d)
whereby
Ctot = total capacitance
C1= capacitance or feed through
ε0= dielectric constant of air
εr= rel. dielectric constant of product
D= diameter of vessel
d= diameter of probe
L= length of probe immersed in
product in meters
If the product conducts, the capacitance is
determined by the thickness and
properties of the insulating material
surrounding the probe. Equation (1)
applies, whereby the variable D is now the
diameter of the probe with insulation. In this
case the capacitance varies by approx.
300 pF/m.
Measurement is independent of dielectric
constant and not affected by changes in
this variable.
In an open vessel, the level is derived from
the hydrostatic pressure exerted by a
column of liquid on a probe placed at its
foot. The pressure exerted is:
p1=ρx g x h (2)
whereby
p1= hydrostatic pressure
ρ= density of the liquid
g = acceleration due to gravity
h = height of the liquid column.
Assuming a constant density, the level of
the liquid can be calculated from the
pressure measured by the Deltapilot.

2 Installation
This Chapter describes:
•The probes for use with the Silometer FMX 570
•Silometer installation in a rack or Monorack housing
•Transmitter wiring
•Sensor connection.
•Technical data.
Warning!
•The Silometer FMX 570 transmitter must be installed outside explosion hazardous
areas.
2.1 Probes and sensors
Table 2.1 lists the probes most frequently used with the Silometer FMX 570 transmitter.
In addition to those listed, all 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 constants Deltapilot S sensors and EC 37 Z/47 Z inserts for capacitance probes are supplied with
the sensor constants zero frequency »fo« and sensitivity »∆f« or »S«. For Deltapilot S
sensors the constants are printed on a label stuck inside the sensor head, for inserts
they are printed on the name plate, see Fig. 7.1, Section 7.3.
Note these constants and enter them into fields V3H5 and V3H6 during commissioning,
Section 4.1. This dispenses with the need for a recalibration of the transmitter on
replacement of the sensor or insert.
