Watchlog Wireless Linear Position Sensor

Watchlog wireless linear position sensors transmit movement in mm readings to a range of wireless receivers/base stations (PC, 4-20mA, cloud etc). There are two wireless transmitter options: the first is a battery-only solution using 2x AA batteries and the second is powered by either 2xD cell batteries or a 9-18VDC external supply. Settings for the wireless transmitters can be adjusted via the free Watchlog Wireless Toolkit.

The linear sensors are supplied with 5mm diameter rod end connections, coming in 11 standard stroke lengths from 25mm up to 450mm.  Accuracy is +/-0.5% and Linearity is 0.1mm or better.
