BIQ bimetal current meter

BIQ bimetallic ammeter with drag indicator (maximum ammeter)

Bimetallic ammeter with red slave pointer for displaying the maximum value. The instrument is based on two bimetallic spirals working against each other - one current-controlled, the other temperature-compensating - and provides reliable measurements in the temperature range from -10°C to +55°C.

The thermally inert measuring mechanism displays the average effective value - short-term current peaks are suppressed. Ideal for monitoring the thermal load of cables, lines and transformers.

A sealable reset button allows the maximum value pointer to be manually reset to the current measured value.

Features:

1. Accuracy class: 3
2. Thermal delay: approx. 15 minutes
3. Trailing pointer (maximum display) with reset button
4. Connection via current transformer (secondary 1 A or 5 A)
5. Overload resistance according to DIN 43780:
6. Continuous: 1.2 × IN
7. Short-term: 10 × IN for 1 second
