First, the working principle of the displacement sensor MPS type rope converted into mechanical displacement measurement, the signal is linearly proportional. The measured object is displaced, the pull rope connected thereto, rope drive mechanism to drive the sensor and the sensor element synchronous rotation; when displaced backward movement, the sensor device will automatically maneuver inside the recovery rope and the rope stretch close the process of maintaining the tension constant, and the output is proportional to the amount of movement of the rope of the electrical signal. This product is based on the use of micro-vibration environment design and installation of products. Second, the main features of MPS Series reasonable precision sensor design, using high-precision sensing element, the sensor is small, easy to use, good sealing, high accuracy, temperature error is small, long life and other advantages. The sensor is not only suitable for linear motion of the mechanical objects displacement measurement, more suitable for mechanical objects as curvilinear motion displacement measurements. V. Precautions 1, install cable displacement sensor should be based on the trajectory of the measured point, so try to pull head pull the rope exit plane perpendicular to the sensor. Using the bottom four screw holes, according to on-site facilities and machinery installation space required, direct installation or use additional protective or other machinery, stainless steel cable installation, horizontal angle should be noted, that try to make the cable from the outlet to the mobile site institutional, horizontal sliding at work, maintain a minimum angle (tolerance + / -30) to ensure measurement accuracy and the cable's life, the body is stainless steel wire rope plus fluoride layer, do not let the external force cuts ﹑ ﹑ impact and other improper burning things happen: excessive dust or dust accumulation ﹑ enough to damage the cable internally storing items pulley or cable outlet will cause damage, leading to uneven operation failures. 2, is not installed on the bench or sit in front of fixed, do not hand out or other products will ropes and let yourself instantly spring back. This will result in cable breakage, damage and personal safety body structure. When the sensor is manually pulled the rope, you should gently pull head back, let go of the rope to retract automatically prohibited, otherwise, cable head to the impact acceleration sensor may cause damage. Steel rope out, you should also pay attention to prevent excessive force twisted rope, the rope to avoid permanent deformation. 3, the withdrawn amount of the sensor head cable should work within its effective length, to avoid out to the limit, so that the rope excessive force and damage. MPS-S and MPS-M series reciprocating instant acceleration must not be more than 1 m / sec; MPS-L and MPS-LP series reciprocating instant acceleration must not be more than 0.5 m / s; This will cause cable break, I am afraid the company does not assume the responsibility of four outside this range, the sensor has a valid operating range, in this range segment with output voltage changes pull out the head (or on request to adjust the output). The indicators have been adjusted at the factory calibration. If you are using the non-linear motion of the body, please install the appropriate pulley running. 5, all devices are factory-sensor precision adjustment, special personnel need professional maintenance, repair without removing the user. Any fault, please contact our technical staff, will be mailed back to our original products, we will as soon as the user testing and maintenance. If found unauthorized disassemble, damage or adjust other phenomena, the products will no longer be included in the scope of our warranty products, due to the resulting inconvenience, please understand user. 6, do the sensor output line together with the power transmission line, can not be placed near a 7 switchboard in high dust, humidity and other harsh environments need to increase protective measures
