The load and leakage resistance must be large enough that low frequencies of interest are not lost. A simplified equivalent circuit model (top of Figure 3) can be used in this region, in which C s represents the capacitance of the sensor surface itself, determined by the standard formula for capacitance of parallel plates.
The digital capacitive technology is based on a non-contacting ceramic sensor mounted inside the load cell body. As the load cell contains no moving parts and the ceramic sensor is not in contact with the load cell body, the load cell tolerates very high overloads (up to 1000%), sideloads, torsion, and stray welding voltages.

A Safe Load Indicator (SLI) or an Automatic Safe Load Indicator (ASLI) is a device which is installed on mobile or portal cranes to alert the operator if the lift is exceeding the safe operating range of the machinery. [1] In some cases, the device will physically lock the machinery in circumstances it determines to be unsafe.
Industrial capacitive sensor. Capacitive displacement sensors are a kind of non-contact displacement sensor, measuring the position and change of position in capacitive materials to a high resolution. [1] They are also able to measure the thickness or density of non-conductive materials. [2]
Calibration is performed by adding a known weight at a known angle. In a soft-bearing machine, trial weights must be added in correction planes for each part. This is because the location of the correction planes along the rotational axis is unknown, and therefore it is unknown how much a given amount of weight will affect the balance.
Timken OK Load is a standardised measurement that indicates the possible performance of extreme pressure (EP) additives in a lubricating grease or oil. The units of measurement are pounds-force or kilograms-force. This measurement is performed using a special test machine and standard block and ring test specimens.
The topic of available gear ratios has been widely debated due to the numerous applications of this transaxle. The 1987 GM Getrag Service Manual [1] confirms that there are at least two versions of the Getrag 282. According to the manual, the two versions were sold under 5 different part numbers based on body and engine usage.
MAP sensor data can be converted to air mass data by using a second variable coming from an IAT Sensor (intake air temperature sensor). This is called the speed-density method. Engine speed (RPM) is also used to determine where on a look up table to determine fuelling, hence speed-density (engine speed / air density).
