You can combine Digital Probes, Linear Encoders and other digital modules to suit your individual applications. It s also eliminates bulky and complex cabling of conventional probes The distance capability probe-to-computer up to 1km without degradation in performance (Orbit) Network capability (Orbit) Compatibility to industrial standards (Sine wave) Calibration certificates in mm or inches CE marked as fully compliant to EN and EN System configuration The Linear Encoder consists of the probe head and the Probe Interface Electronics (PIE) which can be connected directly to a Solartron Digital Readout, a PC or a PLC via Solartron s Orbit Network System. lternatively sine wave output variants are available and allow full compatibility with all existing system. standard industrial plug replaces the PIE. Probe head The Linear Encoder probe head contains a high-accuracy optical scale, together with a precision mechanical bearing assembly. For maximum accuracy, a fused quartz glass substrate is used to minimise temperature effects, giving a very high level of performance over the full stroke. reference mark is included on the scale to facilitate absolute measurement. Probe Interface Electronics (PIE) Orbit versions only Housed in a custom designed connector, the Probe Interface Electronics convert the signal from the probe head into a digital format (Orbit). PIE connectors can be plugged straight into Digital Readout or clipped together using the T-con. Sine wave output n industry standard connector is used, for the voltage and current outputs. This enables the sine wave Linear Encoder to connect to Solartron s IBox and any industrial standard interface/ electronics. Solartron is a world leader in analogue and digital measurement. Underpinned by ISO9001 approval, the company s commitment to superior products at competitive prices demonstrates that customer satisfaction is our main priority.

(PIE including probe head) *ccuracy: The accuracy, we specify, of the Linear Encoder is +/- 0.4, 0.5 or 1.0µm depending on the stroke length. However the maximum difference between any two calibration points on the calibration certificate, supplied with each Linear Encoder, will never exceed 0.4, 0.5 or 1.0µm depending on the stroke length. Example: Use an LE25 mounted in a gauge stand and connected to a DR600 to measure a gauge block that is exactly 20mm. Zero the reading when the probe tip is in with the base of the stand, then place the gauge block on the stand and measure it. Ignoring any errors in the gauge block itself and assuming that it is perfectly in with the base of the stand, the DR600 will display the size of the gauge block as measured by the Linear Encoder. This will be within the range mm to , i.e. 20mm +/-0.5µm.
