SIP 305M Universal Length Measuring Machine

We no longer offer this product. If you want repair service or a custom modern equivalent, contact us.

This is an SIP 305M Length Measuring Machine that has just been refurbished. All of the electronic and opto-electronic components in the measuring system have been replaced with new assemblies designed specifically for this instrument. The new components have far better reliability and performance than the original system, and have been aligned and adjusted to factory specifications. A standard Heidenhain-specification output from the measuring scale means that the digital readout can easily be changed at any time in the future.

Although the instrument is designed for operation at 20°C, both the scale and bed are made from materials with coefficients of expansion very similar to that of steel, so exact temperature control is not necessary in most cases where the work and instrument are equilibrated.

The included Heidenhain/Metronics Gage-Check digital readout has been configured especially for this instrument, and includes 2 LVDT inputs in addition to the main scale input so that a lever probe can be connected without disconnecting the internal null probe. The Gage-Check can either function as a standalone instrument, or in conjunction with an external computer.
