OPERATION MANUAL FOR THE D5 AND D6 SERIES OF DISPLACEMENT

TRANSDUCERS

1. INTRODUCTION

Our standard range of AC energised LVDTs are for use in many applications including

those where ambient temperature or vibration are too high to allow the option of integrated

electronics. These AC LVDTs are a compact short stroke series and can be used

whenever physical space is limited.

The D5 and D6 requires separate signal conditioning and will deliver its optimum

performance when energised with between 0.5V and 7V rms at 5kHz using a high quality

carrier amplifier, such as those available from RDP.

The D5 and D6 are available as either unguided or spring return versions.

2. HANDLING PRECAUTIONS

2.1 Do NOT pull the cable.

2.2 The cable should be positioned away from moving components and correctly

protected and supported.

2.3 If the cable is flexed, then a minimum bend radius of 150 mm should be maintained.

2.4 Protect the transducer from extreme shock or vibration.

2.5 Ensure the transducer pressure rating is not exceeded.

2.6 Do not energise with a voltage higher than 7 volts rms.

2.7 Do not use below -20ºC or above 100ºC.

3. INSTALLATION

Page 3 of 5

3.1 Mount the transducer by clamping the body. A suitable mounting method is with the

body clamped by a split block type of clamp as shown below:

3.2 On a free armature version, the armature (probe) should be mounted on the moving

part to be measured so that the armature moves centrally in the bore of the

transducer body.

3.3 On a spring return version, the probe tip is positioned against the part to be

measured.

3.4 The standard cable has a polyurethane sheath (jacket) with an overall copper

screen (shield). It has a diameter of 2.9/3.25 mm and a length of 2m (unless

ordered with special cable length).

4. ELECTRICAL CONNECTIONS

4.1 The D5 and D6 transducer requires an oscillator –demodulator type instrument

such as one of the following RDP instruments: S7AC, S7M, S7TW, 621, DR7AC,

E309, E725-AC.

Note: the black wire is not used when connecting to RDP instrumentation. Ensure that this

wire is insulated: it must not be allowed to short to other connections or screen.

The yellow and green are in-phase when the probe is fully extended.

4.2 The cable screen (shield) is not connected to the body of the transducer. It should

be grounded at the instrument.

4.3 If it is ever required to change the phase relationship eg change from standard

positive display or signal voltage for a probe movement outward from null to a

negative display, then simply reverse the energisation connections at the instrument

connector.

5. CALIBRATION

Page 4 of 5

Full calibration details of a D5 and D6 transducer with an RDP instrument are contained in

the Technical Manual for the particular instrument.

The general principles are:

5.1 Zero the instrument.

5.2 Move the transducer actuator (probe tip) to its centre stroke (null) position. The

instrument will read zero or output zero voltage (depending on type).

5.3 Move the actuator to the full stroke position by using a micrometer, slip gauge or

similar precision method.

5.4 Adjust the gain (span) of the instrument to obtain the requested full-scale display, or

output, from the instrument.

6. MAINTENANCE AND INSPECTION

6.1 The transducer is fairly well protected from water splash, oil and dust by the rubber

gaiter, where fitted. This gaiter should be regularly inspected to ensure it is

functioning correctly and is not torn or holed.

6.2 Check that the cable is undamaged.

6.3 The insulation resistance, between primary and secondary coils and between coils

and case, should be a minimum of 100M ohm.

6.4 Check that the black core, when not used, is correctly insulated.

7. WARRANTY AND SERVICE

Page 5 of 5

WARRANTY.

R.D.P. Electronics products are warranted against defects in materials or workmanship.

This warranty applies for one year from the date of delivery. We will repair or replace

products that prove to be defective during the warranty period provided they are returned

to R.D.P. Electronics.

This warranty is in lieu of all other warranties, expressed or implied, including the implied

warranty of fitness for a particular purpose to the original purchaser or to any other person.

R.D.P. Electronics shall not be liable for consequential damages of any kind.

If the instrument is to be returned to R.D.P. Electronics for repair under warranty, it is

essential that the type and serial number be quoted, together with full details of any fault.

SERVICE.

We maintain comprehensive after-sales facilities and the instrument can, if necessary be

returned to our factory for servicing.

Equipment returned to us for servicing, other than under warranty, must be accompanied

by an official order as all repairs and investigations are subject to at least the minimum

charge prevailing at the date of return.

The type and serial number of the instrument should always be quoted, together with full

details of any fault and services required.

IMPORTANT NOTES.

1. No service work should be undertaken by the customer while the unit is under

warranty except with the authorisation of RDP Electronics.

2. If the instrument is to be returned to R.D.P. Electronics for repair, (including repair

under warranty) it is essential that it is suitably packed and that carriage is insured

and prepaid. R.D.P. Electronics can accept no liability whatsoever for damage

sustained during transit.

3. It is regretted that the above warranty only covers repairs carried out at our factory.

Should the instrument have been incorporated into other equipment that requires

our engineers to perform the repair on site, a charge will be made for the engineer's

time to and from the site, plus any expenses incurred.

The aforementioned provisions do not extend the original warranty period of any product

that has been either repaired or replaced by R.D.P. Electronics.

THIS WARRANTY MAY BE NULL AND VOID SHOULD

THE CUSTOMER FAIL TO MEET OUR TERMS OF PAYMENT.
