The Celesco SR1 series string pot sensor is now available with an incremental encoder measurement source. The SR1E, which is available exclusively in the UK from Variohm EuroSensor, has a measuring range up to 3m with a resolution of 100 pulses per 25mm of travel (+/- 2 pulses). The unit is housed in a polycarbonate enclosure protected to IP67.
The sensor's maximum velocity and acceleration are 2m/s and 10g respectively. The operating temperature range is from -20ºC to +85ºC and the overall accuracy is +/- 0.1% full scale. Repeatability IS +/- 0.05% full scale.
As with all string pot or cable extension sensors from Celesco, installation is very straightforward with no critical alignment required. The nylon coated stainless steel cable is fully spring loaded, is easily attached to the object under motion and fully retracts into the body of the SR1E ensuring a compact installation envelope of around 200 x 120 x 100 mm (w x h x d).
