Specifications Glossary

Capacity: the recommended maximum weight or force that can be applied to the load cell
Non-Linearity: the greatest difference of the calibration curve from a straight line drawn between the no-load and the rated outputs; depicted as a percentage of the rated output; only calculated on increasing load
Non-repeatability
(Repeatability):
the greatest dissimilarity between load cell output readings for continual loadings under the same environmental and loading conditions
Hysteresis: the greatest difference between load cell output readings for the same applied load; one reading gotten by escalating the load from zero, the other by lessening the load from rated output
Output: the load cell's produced signal (current, pressure, voltage, etc.); when directly comparative to electrical excitation, the signal must be expressed in like terms (volts per volt, per ampere, etc.)
Compensated Temperature Range: compensated is the temperature range over which the load cell is compensated to keep the explicit limits within for rated output and zero balance. Safe is the temperature extremes within which the load cell will function without everlasting unfavorable change to any of its performance characteristics
Operating Temperature Range: this is the temperature range in which the load cell can be safely used without any breakdown of electrical or mechanical components.
Environmental Protection Level: An IP rating is widely used to express the sealing conditions of the load cell, low numbers like IP54 usually only allow dust protection where an IP67 rating is protection against water ingress.
Bridge Resistance: Corner To Corner is the load cell's circuit resistance measured at specific adjacent bridge terminals; at standard temperature; no load applied; and with open-circuited electrical excitation and output terminals Excitation is the load cell's circuit resistance at the electrical excitation terminals; at standard temperature; no load applied; and with open-circuited output terminals Signal is the load cell's circuit resistance measured at the output signal terminals; at standard temperature; no load applied; open-circuited electrical excitation terminals
Proof Load: All load cells supplied by Inscale are proof loaded to this overload percentage to ensure integrity of the load cell design. This becomes important when building custom designed units.
Ultimate Breaking Load: This means exactly this, this is the percentage overload at which the load cell will suffer damage or mechanical failure.
Excitation Voltage: the voltage or current directed to the input terminals of a load cell
Insulation Resistance: the DC resistance calculated between load cell circuit and load cell structure; typically measured at 50 volts under average test conditions
Zero Temperature Coefficient: a change in temperature of the load cell has created a change in the zero balance; often expressed as a percentage of zero balance per degree of Centigrade temperature change
Span Temperature Coefficient: a change in temperature of the load cell has created a change in rated output; often expressed as a percentage of load per degree of Centigrade temperature change
Connection Type: this is the means in which the load cell communicates with the outside world. Standard connections are via screened multi-core cable, however other forms of connections are available.
