Features

Standard Model for On-Machine Measurement

This model can handle a variety of use cases, such as for outer diameter, inner diameter, width, and spline measurements. Also, the model is ideal for harsh environments, such as inline measurement on grinders.

High Precision Mechanism

The internal mechanism is free from any parts that slide or wear, which maintains high precision over a long period.

High Durability and High Rigidit

The adoption of our original L-shaped leave-spring fulcrum provides superior precision, durability, and rigidity.

Outstanding Reliability and Maintainability

As a precision measuring instrument operating in the harshest environments, the PULCOM Σ’s delivery record speaks for itself. In addition, a cable separation type is also available for convenient maintenance when installing in a machine.

E-TS-1□□□B-T (For details, please make Inquires to our sales office.)

For each model we offer "T" type whose measuring head and cable can be separated, making maintenance extremely easy. Only the measuring head can be removed, so maintenance/repair is even with the cable drawn into the machine.
