High Temperature Sensors
1 . Route a cable from the sensor to a Badger Meter flow monitor/transmitter . The cable can be extended up to 2000 feet,
using 2-conductor shielded 20 AWG or larger stranded copper wire . Be sure to leave enough flexibility in the cable or
conduit to allow for future service of sensor, if necessary .
2 . Connect to the cable inside the sensor electronic housing on the Series 220 sensors, or attach to the sensor cable on the
Series 225/226 and connect with standard wire nuts .
3 . When connecting to a Badger Meter flow monitor or transmitter, locate the section of terminal strip on the monitor
labeled
SENSOR INPUT
or
SENSOR
. Connect the red (or white) wire to

ELECTRICAL INSTALLATION SAFETY
The Series 200 sensor is approved, as an entity, as intrinsically safe when installed in conformance with Badger Meter
installation drawing 06-480-002 (
Figure 5
) as specified on the blue label identifying an intrinsically safe sensor .
Entity approval implies that only the sensor is approved as intrinsically safe . Unless power supplies, equipment, and
instruments connected to the sensor are each rated either explosion-proof or intrinsically safe, these devices cannot be
installed in a hazardous area . The referenced installation drawing shows such apparatus located in a non-hazardous location .
Proper interfacing between the hazardous and non-hazardous areas must be provided . It is of absolute importance that
this interface be constructed and that all wiring be performed by qualified contractors . To protect the intrinsic safety of the
installation, the connection of the intrinsically safe sensor to instruments and or power supplies must take place using an
approved intrinsically safe barrier located in a non-hazardous area . These barriers, listed below, are readily available from
various suppliers .
