The 3MTL05 is an economically priced miniature gauging transducer.  The transducer offers excellent repeatability and is fully repairable. 


A return-spring mechanism, engineered from precision ground circular plates, provides tip guidance with virtually friction-free movement.  The design permits measurements at higher dynamic speeds than transducers with conventional coil springs. No contact is made between the tip or shaft and the transducer’s body meaning that measurements of a high repeatability and very low magnitude may be made.



Basic Specifications


Calibrated range +/- 1 mm
Total travel 2.5 mm
Sensitivity 73 mV/V/mm into 2 kOhm


The transducer has a standard 8 mm stainless steel body and comes with a 2 m black oil-resistant cable.  Side-exit cable configuration is possible through the use of a special moulded clip secured by the cable retaining spring.


Calibration components are mounted on a small PCB within the connector housing, this PCB can be replaced by a network of components should custom connectors be required.  Calibration is carried out using a computer controlled process and high-precision optical encoders.  A calibration certificate can be supplied on request.
