Specifications

How to choose Digital indicator

Points to check when selecting, with the values for this product (CSD-891B).

1. 1. Input range matching sensor output

   This product: Input range 0.2 to 3.1 mV/V

   Confirm that the rated output (mV/V) of the strain-gauge sensor falls within the input range of the indicator. If the range is too wide, the resolution cannot be fully utilized; if too narrow, the input saturates. Check against the rated output in the load cell's calibration certificate.

2. 2. Bridge excitation and number of connected sensors

   This product: Bridge power supply 2.5, 5, 10 VDC

   Confirm that the excitation voltage supplied to the sensor is at or below the sensor's recommended excitation voltage. When multiple load cells are connected in parallel, the combined resistance decreases and current increases, so also check whether the indicator can supply the required load conditions.

3. 3. Sampling speed suited to the process speed

   This product: A/D sampling rate 10, 20, 50, 100, 200 回/s

   In processes where the load changes over a short time, such as press-fitting, pressing, or punching, a slow A/D sampling rate may miss peak values. For static weighing, a low speed is sufficient. Note that this value is different from the display update rate (display refresh count).

4. 4. Required display digits and resolution

   This product: Display range -9999~99999

   Determine the required number of display digits from the capacity and minimum scale division, and confirm that the display range meets them. Check not only the display resolution but also whether the actual measurement accuracy, including non-linearity (0.02% F.S. for the listed products), meets the requirement.

5. 5. Mounting method and external dimensions

   Confirm that the panel cutout dimensions and depth fit the panel or enclosure. Select the mounting method as well, such as DIN rail type for installation inside a control panel or board type for equipment integration. Also check the required outputs and communication options, such as CC-Link, RS-232C, or BCD, at the same time.

6. 6. Power supply type and power consumption

   This product: Power supply voltage 100~240 VAC

   Check whether AC or DC power is required, whether wide-range power input is supported, and whether battery operation is possible, according to the installation environment. Power consumption of the listed products ranges from 2.4 to 25 W, which is used for evaluating the power capacity and heat generation inside the panel.
