Electrostatic Sensor

Compact sensor head

The ultra-small design of the sensor head allows it to be installed almost anywhere, even in limited spaces inside a system.

Clearly visible indicator

Large LED clearly indicates the status even when the sensor head and amplifier are separated.

Connectable main unit and expansion units

Up to eight amplifiers can be connected depending on the combination of the main unit and expansion units. This reduces wiring even in applications that require multi-point measurements.

Measurement of static charges relies on the distance between the sensor head and the target workpiece. Measurement error can be corrected by entering the installation distance into the amplifier.

Standard specifications include an independent 3-output judgement system and analogue voltage/current output. By using a communication unit, data from up to 8 connected main units and expansion units can be transmitted simultaneously. The ability to read data and re-write settings from PCs and PLCs contributes to a significant reduction in man-hours required for setup and operation.

Relationship between static electricity and humidity

Static electricity and humidity are correlated: when humidity exceeds 60% RH, static charge is less likely to accumulate. Even during wintertime, when static charges can build up easily due to colder, drier air, static-related problems can be prevented by maintaining a constant level of humidity around target workpieces.

Humidity can vary in the same room depending on the location

Since humidity changes with temperature, humidity can vary in a room depending on the location. Temperature is relatively high around manufacturing systems, which tends to produce lower humidity.
