Smart Static Electricity Sensing:
Making Static Electricity Visible
• Compact sensor head and smart digital amplifier measure
the electrostatic charge quantity of workpieces at all times.
• Multi-point measurements and data logging of the static
electricity quantity can be performed easily.
• Best long-distance, high-precision measurements in the
industry

*1. The measurement may become saturated if the Sensor is too close to an object being measured, even if it is within the measurement voltage
range. Use the distance from the measurement surface (mm) times 1 KV as a guide.
*2. This is the minimum value obtainable when a ZJ-SDA11 Amplifier Unit is connected.
*3. When the ambient temperature is stable at 25°C.
*4. When the measurement distance is 10 mm and the measurement voltage is -5 to 5 KV.
*5. When a Preamplifier is used (excluding the Sensor Head).
