MDI Meters
Beemet maximum demand indicator meters indicate the thermal /time characteristics of load and help audit efficient use of transformer stations and LT distribution feeders. The dimensions comply with the requirements of DIN 43700 and scales with DIN 43802. The performance confirms to IS 1248-83/93. The cases are made of polycarbonate.
The instrument pointer is accompanied by a red slave pointer which is driven by the torque of a bimetallic movement. This slave pointer remains at the max reading position for a successive reading and has to be reset to its default position with the help of a knob.
In the three-pointer MDI meter, a moving iron movement is housed in addition to the bimetallic spring, which indicates instantaneous and maximum demand currents.
