Potentiometric linear transducer SPR18E with electronics

In advancement of the standard SPR18 linear sensor series the E-Version, SPR18E, is realized for better electronic integration. The mechanical detection of linear movement is done by a front and rear guided push rod with accurate sleeve bearings and outside spring return device. This both side bearing construction makes the SPR18E sensor robust for linear motion operation with spring return device. Due to his compact industrial design with 18x18mm in the profile and his spring return device a space-saving and easy integration can be reached up to 100 mm measurement stroke. To ensure high accuracy and long lifetime for a good price performance ratio, the potentiometric measuring principle is realized with a high-resolution conductive plastic resistance element. For facilitating electronic integration, the SPR18E series is equipped with an electronic signal converter board inside the plug housing. Instead of delicate reference voltage, a simple 24VDC±20% power supply can be used. The analogue signal is provided in the typical form with 0…10VDC or 4…20mA. To stable the output signal in the voltage version 0…10V up to 2mA can be driven (for the pure potentiometric signal only 0,001mA is conventional). In comparison to the pure potentiometric transducer, the E-version keeps the true power on function and temperature stability quite well and is EMC approved. For mounting, there are four fixing clamps in the scope of supply. The SPR18E series is available with plug or cable connection.
