The LC703 Series is an economical universal (Tension/Compression) load cell with an extremely low profile. Ranges above 100 lb are Stainless Steel; 100 lb and below are Aluminum. The LC703’s low profile, economical price and rugged design make it suitable for many industrial applications including robotics, automated weighing systems or as part of a batch-process control system.

The LC703 is also available in metric configurations, with 0-5 to 0-500 kgf ranges and metric threads. Please see the LCM703 for complete details, or contact our Pressure department for more information.

How should these load cells be mounted? Is it alright to tighten bolts down into the tapped holes on either side? Is it alright to tighten a nut down onto the top and bottom surfaces? Or must the load only be applied to the threads?

Asked by: Andy8
The load is measured through the threads. If you are using the load cell in compression and are installing something like a load button into the active side threads you would want to leave a slight gap between the bottom of the load button and the surface of the load cell to allow for the deflection of the cell when loaded. Typical deflection would be 0.003"

For the model LCM703-50, what is the unit for the reading after connecting it to the CN16PT controller. Is it in lbs, kg... And for Platinum Monitor, what is the meaning of values and % in the graphing option when connected to LCM703-50

Asked by: Jacky7
The LCM703-50 is a +/- 50 Kilogram load cell. The CN16PT has a scalable display that you can scale to whatever units of measure you wish within the constraints of 4 Digit display (-9999 to +9999 counts). It also has a movable decimal point if you require your display reading to be in 0.1, 0.01 or 0.001 resolution

On the LC703, which side is the active side? How is it different from the other side?

Asked by: Andy8
The active side of load cell one that is farther away from screws on the side of the load cell. The threads on that side react with the internal strain gage element

Are these load cell units calibrated/certified for a certain period of time? Is there a calibration process that can be performed when the calibration/certification expires?

Asked by: KyleH
Thank you for you question? The parts are stored in a controlled environment and would be nominally certified a year from installation. The calibration can not be done in the field for these units. Would need to be returned to Omega for re calibration

For the LC703-1K, is the sensing element a single resistor, a pair of resistors, or a four element bridge?

Asked by: DaveM
Element is a full (4 element) bridge
