About Siemens’ Transducers

This product is intended for use in industrial areas. Operation of this equipment in a residential area may cause interference to several frequency based communications.

The Echomax XPS F series of transducers operates in association with Siemens ultrasonic level monitoring

hazardous seal (XPS 10 F series only)

products.

transducer

The transducer operates by converting electrical pulses that are provided by the transceiver into ultrasonic pulses. When transmitted, these ultrasonic pulses reflect from the material surface and echo

transducer face

back to the transducer. The echo is converted back to an electrical signal, and is interpreted by the Siemens

-3db boundary

tranceiver using our proven Sonic Intelligence™ algorithms.

The effective acoustical energy is emitted from the transducer face and radiated outward, decreasing in amplitude at a

axis of transmission, perpendicular to transducer face

rate inversely proportional to the square of the distance.

Maximum power is radiated axially (perpendicular) from the transducer face in a line referred to as the axis of transmission. Where power is reduced by half (– 3 dB), a conical boundary defining the sound beam, centered about the axis of transmission, is established. The diametric measurement of the cone in degrees defines the beam angle. Impedance matching techniques are used to optimize the transfer of power from the transducer into air and vice versa.

About the…

The XPS F series transducers incorporate an integral temperature sensor that reports the air temperature at the transducer to the transceiver. The connection is transparent, in that both the ultrasonic and temperature components of the transducer use the same leads.

Hazardous Area Applications

The Echomax XPS F series of transducers can be used in hazardous are as.

For the XPS 10 F series transducer, a hazardous seal must be used to suit hazardous area classification. This seal is not supplied by Siemens.

The XPS 15 F comes equipped with a stainless steel coupling suitable for use in hazardous locations.

Mounting

Recommendations

 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 (0.3m for XPS 10 F and 0.45m for XPS 15 F). Refer

to the associated transceiver manual for instructions on setting the blanking value.

 On liquid applications, the transducer must be mounted so that the axis of

transmission is perpendicular to the liquid surface.

 On solids applications, a Siemens Easy Aimer should be used to facilitate

aiming of the transducer.

 Do not over-tighten mounting. Hand tightening of the mounting hardware is

sufficient.

 Secure installation by connecting a safety chain from the transducer to a

structural member.

 Consider the optional temperature sensor when mounting the transducer.

Interconnection

Note:

Installation should only be performed by qualified personnel and in accordance with local governing regulations.

Recommendations

 When using an XPS 15 F transducer, configure the electronic transceiver for

an XCT-12. These two transducers use the same settings.

 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.

Note:

In the interconnection examples that follow:  an XPS 10 F Series transducer is shown. An XPS 15 F transducer can

also be used, but no hazardous seal is required.

 assume that the transducer is located in a Hazardous location (Class I,

Div. 1, Group A,B,C,D or Class II, Div. 1, Group E,F,G.) and the transceiver in a Non-Hazardous (Safe) Location.

Applications

Notes:

 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.

 An XPS 10 F Series transducer is shown in these examples. An XPS

15 F transducer can also be used, but no hazardous seal is required.

Applications

* the use of a TS-3 temperature sensor provides better temperature tracking in

applications where the temperature can change quickly.

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.

Note:

Refer to transceiver manual for programming requirements.

Standpipes

In many applications, access must be made via a standpipe. In such cases, Siemens can provide factory bonded flanged transducers or a 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. As a rule of thumb, the -3 dB cone of the sound beam should not intersect the standpipe wall in applications opening into a vessel or larger area. Otherwise, additional blanking will be required to compensate for the interference zone created by the opening.

Note: When using a stilling well, make sure there is no build-up, welds, couplings, or other debris on the inside of the well wall. This can affect reliability of measurement.

1. Beam should not detect bin bottom. If this occurs, use range extension parameters (on transceivers where available) to omit false echoes. A 6° beam angle (XPS 15 F) represents a rise:run of about 20:1 (10:1 for the 12° beam angle of the XPS 10 F). In most tanks, the transducer should be centered as much as possible (without interference from inlet) for optimum reading range.

2. Sound beam must be perpendicular to liquid surface. If standpipe is used, refer to page 13.

3. Echo has missed improperly levelled transducer.

4. When performing an empty or full calibration, the tank must contain its normal vapour and be at its normal temperature.
