IP69K PROTECTION DEGREE MAKES IT A CANDIDATE for outdoor applications in solar systems, mobile machines, cranes, or lift arms. The sensor comes with a selection of interfaces: analog power or voltage outputs and the digital interfaces EIA-485, EIA-232, CAN, and CANopen. CANopen is available according to CiA 301 with a bit-rate of 1 Mbit/s.

The accuracy of ±0,1° or ±0,07° with temperatures between -15 °C and +50 °C is achieved by internal temperature compensation and a stable mechanical construction. EIA-485 and EIA-232, CAN, CANopen, and switch output inclinometer provide 0,07° accuracy, while 4~20 mA and 0,5~4,5 VDC output inclinometer only provide 0,15°accuracy.

Interference lies at ±0,5 % of the measurement range and the sensor has a cross-axis error of ±0,2 %. The sensor offers 50 Hz refresh rate and 10 Hz bandwidth and a temperature range from -40 °C to +85 °C. It is available for horizontal, vertical, headstand, etc. installation methods. The sensing elements survive up to 1500 g shock while operating.

The Swiss company offers physical sensors, geometrical sensors, power supplies, and e-compnents. It has thirty years of experience in the field. Pewatron is an independent company of the Angst+Pfister Group that is part of a worldwide network with more than 1000 employees.
