High-precision Electrostatic Sensor

SK series

In-line type SK-050/1000

Compact sensor head

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

Clearly visible indicator

Large LED clearly indicates the status even when the amplifier is not visible.

Connectable main unit and expansion units

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

Installation distance correction

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.

Multiple output options

Standard specifications include an independent 3-output judgment system and analog voltage/current output. By using a communication unit, data from up to 8 connected units can be transmitted simultaneously. The ability to read data and re-write settings from PCs and PLCs significantly reduces man-hours required for setup and operation.

STATIC ELECTRICITY, HUMIDITY Simultaneous measurement [Industry’s first]

By measuring the static charge and humidity at the same time, you can more accurately identify whether a particular area is likely to have static-related problems. This helps identify optimal anti-static measures, including humidification and other procedures such as installing an ionizer.

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 the winter, when static charges 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 generally higher around manufacturing systems, which tends to produce lower relative humidity.
