5534/5535/5544/5545 SIGNAL CONDITIONER SENSORS
Installation Manual
OVERVIEW
These Accelerometer Signal Conditioners ac -
cept signals from machine casing mounted
Metrix Seismic Accelerometer or most
competitve accelerometers and produce a
4-20 mA current source output proportional
to the measured variable. The detection
circuit is responsive to true RMS vibration
but the output may be scaled either to peak
or RMS units. A green LED indicates sensor
and cable integrity. In the event of sensor
failure, the LED extinguishes and the output
current is driven below 3.6 mA, thereby
signaling a malfunction. A BNC connector
gives access to the buffered input signal for
local analysis. Optional features for either
model include filters and galvanic isolation
between input, output and power supply.
INSTALLATION
Each signal conditioner is supplied with
either a flat mounting base or a DIN rail
adapter. When mounting in the Metrix
Part #7595 explosionproof housing, the
DIN rail adapter version must be used. The
Metrix Part #7876 and Metrix Part #8172
weatherproof housings may be specified
for flat base or DIN rail mounted signal
conditioners. For the best results, the signal
conditioner should be installed within 1000
feet (300 m) of the transducer.
WIRING
SENSOR (Signal Input): Connect the trans -
ducer or charge amp output cable leads
to these terminals. If the transducer is a
self-generating velocity pickup, polarity is
arbitrary unless the signal polarity at the SIG
