4.8 SHA-6 energy meters universal scanning head; code ZII20162
SHA-6 is a scanning head that eases the test of energy meters. It is an universal scanning head
because it can be used both with LED impulse electronic meters and Ferraris rotating disk meters;
selection is performed via a switch located on the scanning head. In addition to this, a knob allows
to adjust the sensitivity of the head.
With rotating disk the sensor uses a green light beam that optimizes the recognition of any type of
mark.
With LED recognition the following specification applies:
. Impulse duration: more than 60 us;
. With an LED signal having a space ratio 1:2, the frequency must be less than 500 Hz.;
. Light wavelength: 500 to 960 nm (red).
The option includes:
- The support that allows to keep the scanning head in front of the energy meter: maximum height
175 mm;
