57-606 ECLIPSE Model 706 Guided Wave Radar Transmitter
Applications
1. Plastic pellets, sugar: Dielectric constant 1.9–2.0
2. Grain, seeds, sand: Dielectric constant 2.0–3.0
3. Salts: Dielectric constant 4.0–7.0
4. Metallic powder, coal dust: Dielectric constant >7
NOTE: Contact the factory for those applications requiring addition
pull down forces such as cement, heavy gravel, etc.
Mounting recommendations
• To reduce forces, utilize the standard 5 lb. (2.3 kg) stainless
steel weight at the bottom of the probe instead of securing
the probe to the vessel.
• Mount the probe at least 12 inches from the wall. Ideal
location is
1

to
1
⁄

the diameter to average the angle of
repose.
• A metal flange must be used when mounting on plastic
vessels.
1. Ensure that the process connection is the correct threaded
or flanged mounting.
2. Make sure that there is at least 1" (25 mm) spacing between
the active cable and any part of the tank (walls, stillwell,
pipes, support beams, mixer blades, etc.)
3. Carefully place the probe into the vessel. Properly align the
gasket on flanged installations.
4. Align the probe process connection with the threaded or
flanged mounting on the vessel.
5. For threaded connections, tighten the hex nut of the probe
process connection. For flanged connections, tighten flange
bolts.
Bulk Solids Twin Flexible probes can be shortened in the field:
6. a. Loosen and remove the two cable clamps.
b. Slide the weight off of the probe.
c. Cut the cable to the required length.
d. Remove 12 inches (30 cm) of the rib between the two
cables.
e. Strip 9 inches (23 cm) of coating from the two cables.
f. Slide the weight back on to the probe so that there is 8.5
inches (21 cm) from top of weight to the end of the
cables.
g. Reinstall the two cable clamps and tighten.
h. Enter new probe length (in the appropriate Level Units)
into the transmitter.
