7.7 Sensor to Transmitter Cable Connections
The sensor to transmitter cable is used to transmit sensor signals and
information between the transmitter and the sensor, and provides
electrical power to the sensor pre-amplifier board mounted in the
sensor cover.
The sensor to transmitter cable consists of 12 twisted pairs of 20 AWG
conductors with an overall cable shield encased in a PVC jacket. The
standard cable has an operating range of -4 ºF to 221 ºF (–20 ºC to
105 ºC). The cable is UL Listed (UL Standard 13, Type PLTC) and
CSA Certified (CSA C22.2 No. 214, PCC FT4). The outer diameter of
the cable is 0.61 inch (15.5 mm) nominal.
Optional low temperature and armored cables are also available.
Please contact your local distributor or CiDRA Corporation for more
information.
The sensor to transmitter cable is furnished with a NEMA 4X
connector attached to the sensor head end. The transmitter end can
be cut to length and terminated at installation.
The sensor to transmitter cable can be either run in cable trays or
through conduit in accordance with local practice.
7.7.1 Sensor End Cable Attachment
Once the cable is run, attach the connector on the sensor cable end to
the mating connector on the sensor cover. Align the keyway on the
sensor connector and latch in place.
