Installing The Transducer; Installing The Temperature Sensor - Siemens OCM III Instruction Manual

INSTALLING THE TRANSDUCER

Hazardous voltage present on transducer terminals during operation.
Note: When using the XRS-5 transducer with the OCM-3, use the TS-2 external
temperature sensor. The internal temperature sensor in the XRS-5 cannot be used.

INSTALLING THE TEMPERATURE SENSOR

16
Basic Wiring – Transducer
Basic Wiring – Temperature Sensor
Max cable run 183 m (600 ft) of
RG-62U or equivalent. Cable must
be run in a grounded metal conduit
with no other cabling (except
Temp. Sensor cable).
Ground shield at OCM-3 only.
Insulate shield at junctions to
prevent inadvertent grounding.
In order to compensate for uniform
temperature change in the air
between the transducer and the flow
surface, the temperature sensor
must be connected to the OCM-3.
Maximum cable run 183 m (600 ft) of
Beldon 8760, 1 pair shielded/twisted,
18 AWG or equivalent.
Temperature sensor cable can be
run with the transducer cable in a
grounded metal conduit.
Ground shield at OCM-3 only.
