•
Easy setup
Approved for hazardous locations
NEMA 4X, IP67 impact-resistant enclosure
Simple two-step calibration
Two modes of input allow for easy servicing, with no
interruption of loop required
■ Application
7
The RD100 is very versatile. It can be installed indoors or
outdoors, in hot or cold environments, and in safe or hazardous
areas.
It has been approved by FM and CSA as Intrinsically Safe and
non-incendive, and operates from -40 to +85 ºC
(-40 to +185 ºF), adding only 1 V to the loop.
Calibration consists of a quick two-step process involving the
adjustment of only two non-interacting potentiometers.
• Key Applications: remotely displays process variables in level,
flow, pressure, temperature, and weighing applications, in a
4 to 20 mA loop.
