LTH Compression Sensor Family Manual Mechanical Installation The following items should be observed to avoid damage to the LTH sensor during installation and usage. • 1. Do not pull on or carry sensor by cable. Avoid conditions that exceed the sensors IP rating. Store in a dry area without fixtures. MAXIMUM MOMENTS AND OFF-AXIS LOADING • Extraneous load information can be used to assist in determining if the sensor can withstand any unavoidable off-axis loads and moments. Extraneous load information can be found at: http://www. futek.com/extraneous-load-factor An extraneous how-to guide can...

LTH Compression Sensor Family Manual Mounting and Installation Below is information for proper mounting and installation. Refer to the sensor spec sheet for thread information and proper load cell orientation to maximize performance and limit cable interference. • Measurements are called out on the sensor spec sheet and have the following tolerances based on the number of decimal points present. DECIMAL FORMAT 2. Support on the outer bottom (Fixed End) ring only. 1. Support surfaces must be flat and inline Non-loading surface, do not contact 3. Load must be applied uniformly on entire...

LTH Compression Sensor Family Manual Cable Care and Routing • Below is information for proper cable care and handling. Cable material type and length can be found online in the sensor description page. 1. Avoid stress and movement on cable to avoid damage. 2. Properly secure sensor cable to limit cable movement influence. 3. Avoid bending the strain relief. Bends in the cable should not exceed a radius of ten times the diameter of the sensor cable for dynamic, or moving, applications and not exceed a onetime static, permanent, bend of two to three times the diameter of the cable. CABLE...

LTH Compression Sensor Family Manual Shield Usage and Connections • Cable shielding should be grounded on one end, either the sensor side or instrument side to avoid ground loops. Jacket Shield • A shield connection listed as floating on a sensors spec sheet means the cable shield is not connected on the sensor side and may be connected on the instrument side to ground. Power Supply • A yearly calibration is recommended. But verification and calibration period shall be defined based on application, conditions, endurance and usage. A shunt is an external resistance applied across two points...

LTH Compression Sensor Family Manual Troubleshooting When troubleshooting, we recommend that the sensor be removed from any fixtures. In order to confirm that that sensor is operating correctly, we suggest placing the sensor on a firm surface, and to apply a known load. We also recommend using a volt meter with a clean power supply to confirm the sensor is operating correctly. POSSIBLE CAUSE High zero output • Sensor is under preload • Fixtures or bolting stress for causes of pre-load. • Overload shift would not be repairable. • Sensor has been overloaded from too much load, off axis load,...

LTH Compression Sensor Family Manual POSSIBLE CAUSE Zero output drift • Unstable power supply, or noisy power supply, to sensor. • Stability of power supply and noise levels. • Internal damage from liquid exposure is not repairable. • Sensor exposed to temperature change. • For temperature changes or unevenly distributed temperature changes. • Recalibration is available for confirmation of sensor performance. • Sensor exposed to pre-load from fixture or mounting. • Possible loose fixtures and bolts • Sensor exposed to liquid or humidity. Creep in output while under load • Load or fixtures...
