Versions:

• Minicap FTC260: with rod prob e for bulk solids and liquids
• Minicap FTC262: with rope probe up to 6 m (20 ft); for bulk solids
• Relay output (potential-free change-ove r contact / SPDT) with AC or DC power
• PNP output with three-wire DC power Your Benefits
• Complete unit consisting of th e probe and electronic insert: – simple mounting – no calibration on start-up
• Active build-up compensation – accurate switch point – high operational safety
• Mechanically rugged – no wearing parts – long operating life – no maintenance
• The rope probe of the Mini cap FTC262 can be shortened – optimum matching to the measuring point – less stocks required

Minicap FTC260, FTC262 Endress+Hauser 3 Function and system design Measuring principle Point Level Detection A metal plate at the end of the probe, within the insulation, the integrated counter-electrode and the surroundings combine to form the two electrodes of a capacitor. If the probe is covered or free of process medium, the capacitance changes and the Minicap switches. Active Build-up Compensation The Minicap detects build-up on the probe and compensates for its effects so that the switch point is always observed. The effects of build-up compensation depend on:

• the thickness of the buildup on the probe,
• the conductivity of the buildup,
• the sensitivity setting on the electronic insert. Measuring System Minicap is an electronic switch. The complete measuring system consists of:
• the Minicap FTC260 or FTC262
• a power supply and
• controllers, switching devices, signal transm itters (e.g. lamps, horns, PCS, PLC, etc.) L00-FTC26xxx-14-06-xx-xx-001 Point level detection in silos containing solids FTC262 FTC260 MAX MIN FTC260

Function Range There is a loose relationship between the dielectric constant εr and the density ρ of the material. The table on the left indicates whether the Minicap can be used or if application limits are exceeded. In general: If the dielectric constant of the process medium is not known, then the bulk density can be a deciding factor. Experience shows that the Minicap functions in foodstuffs with a density of 250 g/l and above or in plastic or mineral materials with a density of 600 g/l and above. Setting the Sensitivity The Minicap is so calibrated at the factory that it correctly switches in most materials. Greater sensitivity can be set using a switch on the electronic insert. This is necessary if there is very strong build-up on the probe, or if the dielectric constant εr of the material is very small.

For silos made of non-conductive materials, the external earth wire of the Minicap must be connected to a conductive and earthed component which is earthed near to the silo. The protective earth can be connected to the internal earth terminal of the Minicap. Connections can be made with standard instrument cabling. See TI00241F/00/EN for information on EMC (testing procedures, installation). Connect the potential matching lead (PAL) when using in dust explosion hazardous areas. Note national regulations!

Mounting Point Note the angle of the material mounds and the outlet funnel when determining the mounting point or probe length of the FTC262. NOTICE The material flow must not be directed at the probe!

Minicap FTC260, FTC262 Endress+Hauser 9 Installation instructions FTC260 Correct Installation a. Minimum distances: To prevent mutual interference with the FTC260, there must be a minimum distance of 200 mm (7.87 in) between two probe tips. b. Mounting point: Tip of probe points slightly downwards so that process medium can slide off more easily. The protective cover protects the probe rod from collapsing mounds or mechanical strain at the outflow when the Minicap FTC260 is set to minimum detection. c. Mechanical load: The maximum lateral load on the probe rode must be taken into account when used for minimum detection. It should therefore only be used for minimum detection with loose materials that have good flow characteristics. Incorrect Installation d. The probe may be damaged by inflowing materi al. and cause faulty switching. Cable gland pointed upwards can allow moisture to enter. e. Threaded socket too long with material build-up on the silo wall. (Minimum mounting depth 100 mm (3.94 in) not reached). f. Mounted near build-up in the silo. The probe tip is too near to a silo wall (less than a minimum distance of 200 mm (7.87 in) ).

a. Minimum distances: Sufficient distance from the material filling curtain and the other probe. b. Mounting point: Do not install in the center of the outlet cone. Ensure there is sufficient distance from the silo wall and from material build-up on the wall. c. Mechanical load: Note the tensile strain on the probe rope and the strength of the silo roof when used for minimum detection. Very high tensile forces may occur at the material outlet especially with heavy, powdery bulk materials which tend to form build-up. These forces are significantly greater over the outlet than at the silo wall. For minimum detection Minicap FTC262 should only be used for light, easily flowing solids, and that do not tend to form build-up. Incorrect Installation d. In the center of the material ou tflow; the high tensile forces at this point may tear off the probe or damage the silo roof. e. The probe may be damaged by inflowing material. f. Mounted laterally g. Too near silo wall; when swinging gently the probe can hit the wall or touch any build-up which may have formed. This can result in error switching Correct Installation Incorrect Installation L00-FTC26xxx-11-06-xx-xx-002 General notes and recommendations for installing a Minicap FTC262 point level switch MAX MIN >300 (>11,8) <3000 N <3000 N FTC260 >300 (>11,8) >300 (>11,8) >200 (>7,87) mm (in)
