The PD6100 is a member of the ProVu series of 1/8 DIN digital panel meters that accepts strain gauge & load cell inputs and mV signals up to 300 mV (unipolar) and ± 250 mV (bipolar) for weight indication and force measurement applications. The PD6100's dual-line display and powerful dual-scale capability allows the measurement to be displayed in two different units of measure; gallons (volume) could be displayed on the upper line while pounds (weight) is displayed on the lower line, for example. Another use for the PD6100's dual-line display is to simply show the units of measure on the bottom line. The PD6100 stain gauge meter includes a 5 or 10 VDC power supply to drive the sensors and can be equipped with up to four internal relays and one 4-20 mA output.

A typical application for load cells is in a tank weighing operation. In the following example, this three-legged tank has a load cell under each leg. The three load cells are wired locally in parallel within a junction box. The combined signals are then connected to the PD6100. During field calibration, the weight of the empty tank (zero point) and the full tank weight (full scale) are programmed into the meter. Over time, the tare feature on the PD6100 can account for obstacles like sludge buildup on the bottom of the tank when empty.
