56 Installation Manual, 08/2017, A5E36255466-AC
1. Slide the insulated sleeve onto the cable over wires ①, ②, ③ and ④ but NOT the blue
wire
⑤. Fold back the blue wire.
2. Attached the wall mount RTD crimp lug to the blue wire
⑤ on the cable using a crimping
tool or equivalent.
3. Set aside all remaining parts left in the parts bag.
Black (I+) RTD current high
Blue - Ground (add crimp lug - A5E39272102)
White (V+) RTD voltage high
Green (I-) RTD voltage low
To sensor with BNC connector or to submersible sensor

4. Proceed to the Mounting temperature sensor (Page 56) section.
Mounting temperature sensors
Note
RTD temperature sensors are for the FST030 transmitter only.
FST020 transmitter does not accommodate temperature sensors.
Temperature is used to normalize the liquids sonic velocity in order to properly determine
interfaces and for density determination. Temperature sensors are available in clamp-on
style or in insert (Thermowell) style. Refer to the table below. Both styles incorporate 1000
ohm platinum RTD’s for high precision.
Note
Optional equipment
Temperature sensors are optional equipment. After installation proceed to Commissioning in
the transmitter Operating Instructions.
