1 About this guide
This guide provides basic guidelines for Sensor models. It does not provide
instructions for configuration, diagnostics, maintenance, service,
troubleshooting, explosion-proof, flameproof, or intrinsically safe (I.S.)
installations. If the Rosemount Volume 1 Sensor was ordered assembled to a
temperature transmitter, see the appropriate transmitter Quick Start Guide
for information on configuration and hazardous locations certifications.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or
unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for all
systems used within the facility.
CAUTION
Refer to Product Certification section of this Quick Start Guide
documentation.

3 Rosemount Series 58C sheath cutting
Procedure
1. Determine the length to which the sheath will be cut. The finished
length needs to include an additional 1.5-in. (3.8 cm) for
compression fittings or 2.5-in. (6.5 cm) for spring-loaded fittings (see
Figure 4-1).
2. Remove and save the heat shrink tubing from the rear of the sensor.
3. Place the sensor in a vise, taking care not to overtighten, and position
the tubing cutter on the sheath.
4. Score the sheath to a depth of approximately 1/64-in. (0.4 cm) To
prevent damage to the lead wire insulation, do not cut completely
through the sheath.
5. Firmly grasp the end of the sheath with your hand or a pair of pliers.
Using a sharp snapping motion, break off and remove the excess
sheath material. Take care not to strip or damage the lead wire
insulation while removing the excess sheath material.
Note
If you are unable to easily break off excess sheath material, deepen
the score and repeat Step 5.
6. Replace the heat shrink tubing.
