SCT-013 100 A

Non-Invasive AC Current Sensor Split Core Type Clamp Meter Sensor. SCT-013-000 is a Non-Invasive AC current sensor i.e. it is a current transformer which can be used to measure AC current up to 100 amperes.

Current transformers(CTs) are sensors are for measuring alternating current. They are particularly useful for measuring whole building electricity consumption (or generation for that matter). The split core type such as the SCT-013-000 in the picture is particularly suitable for DIY use. Clip this SCT 013 000 straight on to either the live or neutral wire coming into the building without having to do any high voltage electrical work.

This is a current output  , you can add a burden resistor to measure voltage across  


Package Includes :

1 x 100A AC Current Sensor Module.

52mm PP Plastic Water Liquid Level Sensor (FSWITCH52)
Float level switch is a simple structure, easy to use level
control device, it does not provide power, no complicated
circuit, it has a mechanical switch than the average small
size, long life and other advantages. As long as the material
used in the correct shape and nature of any liquid or
pressure, temperature can be used, which in the
shipbuilding industry, generating equipment, petrochemical
industry, food industry, water treatment equipment, dyeing
and finishing industry, hydraulic machinery, etc. have been
widely application.
How it works: liquid level sensor magnetic reed switch by
having an important and
integral float, float within the magnetic material in a sealed
non-magnetic metal pipe or plastic pipe set one or more
magnetic reed switch, and then the catheter through a or
more with magnetic float, and double-loop control using a
fixed float and reed
switch in the relevant position, the float rises or falls with
the liquid using the ball close to the beginning of the reed
contacts, resulting in open and shut action for level control
or direction (when the float near the reed switch is turned
on; leave the switch off)
