Unicorn Automation Transducers

Unicorn can provide a comprehensive range of Transducers from standard contact probes to customized specials:-

- Frequency Range 500KHz to 50MHz

- Rugged case construction using materials such as Stainless Steel or Titanium for special applications

- Most standard Transducers available Ex.Stock

- Performance Details and Certificates of Conformity available

- Repair and replacement service

- Accessories:- Transducer cables and Wear Shoes

- The range of transducers both for contact and immersion are separated into two general groups i.e.

1. UM Transducers

2. UH Transucers

Transducers designated with the prefix letters UM have the following characteristics as standard;

a) Medium damped element of lead titanate offering good signal to noise.

b) Stainless steel or anodised alloy case with soft finger grips on hand held probes.

c) SMC connectors as standard (other connectors are available if required).

d) Single contact transducers supplied with ceramic wear face.

e) The combined twin compression and shear wave transducers have replaceable wedges and stand off's.

f) UM immersion transducers are suited to through transmission testing techniques e.g. composite testing and are generally housed in stainless steel cases with UHF connectors as standard.

Transducers designated with the prefix letters UH have the following characteristics as standard;

a) Highly damped lead metaniobate element offering excellent resolution and good sensitivity.

b) Stainless steel case with soft finger grips on hand held probes.

c) SMC connector is standard with optional Lemo or Microdot.

d) UH transducers (shear and compression) use a special matching interface to improve pulse shape and energy transmission.

e) Twin compression transducers are compatible with most digital thickness gauges available on the market.

f)Immersion transducers are available with flat, spherical or line focussing.

  • Roller TransducersOpen or Close

    These probes consist of an anodised aluminium body, perspex wheel with sealed bearings to prevent leakage of oil and a soft but wear resistant rubber tyre.

    The element is a medium damped Lead Titanate offering both good penetration and an excellent signal to noise ratio.

    Two sizes of transducer are available, the 25mm diameter which can be held in our own calliper unit or the 75mm diameter to fit individually tailored fixtures.

    Used where dry testing is a necessity in through transmission mode of highly attenuative materials such as composite and porous materials.

    Can be mounted for automated testing or in our own callipers for hand inspection.

    Replacement tyres available.

    Range of frequencies available.

    Range of connectors available.
