Safety Guidelines Warning notices must be observed to ensure personal safety as well as that of others, and to protect the product and the connected equipment. These warning notices are accompanied by a clarification of the level of caution to be observed. Qualified Personnel This device/system may only be set up and operated in conjunction with this manual. Qualified personnel are only authorized to install and operate this equipment in accordance with established safety practices and standards.
ABOUT THE TRANSDUCER The Echomax XPS / XCT series of transducers operates in association with Milltronics ultrasonic level monitoring products. transducer The transducer converts the electrical energy of the transmit pulse from the transceiver into acoustical energy. It then converts the acoustical energy of the echo back into electrical energy for the transceiver receive period.
XPS D Series - Certificate SIRA 01ATEX5262X This equipment may be used in all hazardous dust zones with all conductive and non-conductive dusts. The Type XPS-10D, XPS-15D, XPS-30D and XPS-40D Series transducers have a maximum surface temperature of 135°C (275°F) (Temperature Class T4). These units are certified for use in ambient range of -40 to 95°C (-40 to 203°F). The transducers should not be used outside this temperature range.

MOUNTING DO’S AND DON’TS Special handling precautions must be taken to protect the face of the transducer from any damage. Mount the transducer so that it is above the maximum material level by at least the blanking value. Refer to the associated transceiver manual. On liquid applications, the transducer must be mounted so that the axis of transmission is perpendicular to the liquid surface. On solids applications, a Milltronics Easy Aimer should be used to facilitate aiming of the transducer.
MOUNTING - LIQUID APPLICATIONS Bracket Flexible Conduit flexible conduit steel channel coupling safety chain transducer Flexible conduit mounted transducer should not be subjected to wind, vibration or jarring. Plywood Submersible rigid metal conduit coupling safety chain submergence shield Submersible transducer, used in applications where flooding is possible. 8 Plywood mounting provides excellent isolation, but must be rigid enough to avoid flexing if subjected to loading.
MOUNTING - LIQUID APPLICATIONS (cont’d) Blind Flange nipple welded to blind flange coupling Flange, gasket and hardware supplied by customer. Refer to Liquid \ Applications - Standpipes. Note: Tighten the flange bolts evenly in order to ensure a good seal between the mating flanges. Caution: Overtightening can cause performance degradation. Flanged coupling factory flanged transducer bolt gasket customer flange, flat face only nut Customer flanged standpipe.
INTERCONNECTION Milltronics transceiver ( typical ) Direct Connection For EnviroRanger ERS 500 only, connect all three wires separately. blk wht drain / shield 2 Wire Extension wht For EnviroRanger ERS 500 only, connect all three wires separately. blk junction box drain / shield extend cable using 18 AWG shielded / twisted pair Coaxial Extension When connecting to an EnviroRanger ERS 500, do NOT use coaxial cable, use a 2-wire extension as illustrated above.
DO’S AND DON’TS Installation shall only be performed by qualified personnel and in accordance with local governing regulations. Do not route cable openly. For optimum isolation against electrical noise, run cable separately in a grounded metal conduit. Seal all thread connections to prevent ingress of moisture. Do not run cable near high voltage or current runs, contactors and SCR control drives. 7ML19981AK01.
APPLICATIONS The transducer is to be used only in the manner outlined in this instruction manual. Normally, the transducer requires no cleaning or maintenance. However, if performance changes are observed, immediately shut down the level measurement system and perform a thorough inspection, especially on the transducer.
LIQUID APPLICATIONS - SUBMERGENCE In applications where flooding is possible the transducer▼ can be fitted with a submergence shield. The shield acts as a bell to create an air pocket in front of the transducer face. The associated transceiver▼ interprets this as a flooding condition, and reacts accordingly. Refer to transceiver manual for programming requirements. transducer submergence shield * air pocket * refer to associated instruction manual for assembly details. ▼ on applicable models.
LIQUID APPLICATIONS - STANDPIPES In many applications access must be made via a standpipe. In such cases, Milltronics can provide factory bonded flanged transducers or split flange kit that will readily mate to the flanged standpipe. Another option is to hang the transducer from a blind flange. The standpipe length should be as short and the diameter as large as possible.
LIQUID APPLICATIONS - VOLUME ‘ Alternate ’ ‘ Preferred ’ ‘ Bad ’ tank manufacturer’s full level Maintain full level for full calibration. Above this level erroneous readings will result as level has entered blanking zone. (shaded area) beam angle span : corresponds to tank manufacturer’s empty level. rise Empty level for ‘alternate’ location. Below this level, echo would reflect away from the transducer. may require target to obtain empty reading tank manufacturer’s empty level discharge 1.

SOLIDS APPLICATIONS - TYPICAL Easy Aimer 1 bin wall seams 3 2 filling profile emptying profile 1. Transducer angled to avoid seams in bin wall and aimed at discharge in order to read bin when empty. 3. Transducer too close to material inlet. Falling material will intersect sound beam and cause erroneous readings or loss of echo. 2. Avoid intersecting bin wall seams, structural members and wall irregularities. Otherwise, transducer minimal angle of repose 5 4 discharge 5.
SOLIDS APPLICATIONS - SPECIAL STORAGE BIN WITH AGITATOR infeed agitator 1. Transducer should be kept away from infeed. 2. Where agitators are in use, use the Agitator Discrimination parameter on transceivers where available. 3. Transducer should be aimed away from wall projections. DRYER - WOOD CHIPS infeed drag conveyor typical low level typical high level 1. Transducer should be mounted perpendicular to slope of wood chips. 18 XPS/XCT Transducers 7ML19981AK01.
