3051S ERS Simplifies Installation Practices
1. Independently install each sensor
– Direct-mount without pipe stand, brackets,
and other hardware
– Can be installed by a single instrument tech

2. Wire sensors together
– Non-proprietary electrical wire
– Easy to install around catwalks, on
distillation columns, etc.
– Eliminate insulation and heat tracing
