Electronic Vibration Switch Is Designed As Direct Replacement Of Mechanical Vibration Switches.

These Mechanical Switches being used in yester years have very little merit and served the purpose when the requirement was not stringent. As they rely on large impacts or inertia (both acceleration): they do not respond to gradual increase in vibrations. Nuisance tripping during start-up is an usual problem. Further, sensitivity adjustment is too ambiguous to offer any meaningful translation.

Current Sensors (AC or DC)

LINEAR RANGE : 0 - 150 Amps.
OUTPUT : 0 - 2 VOLTS (NOMINAL) at full rated current
ZERO CURRENT OFFSET : +/- 0.5 mA at zero input current
LINEARITY OF OUTPUT : WITHIN +/- 1% OF full scale input current
SUPPLY VOLTAGE : +/- 12 V DC (+/- 5%)
INSULATION RESISTANCE : 500 meg ohm min at 500 V DC
SIZE : L=47mm, H=41mm, W=13mm
HOLE DIA : 13mm
WEIGHT : 60Gms

Hall effect Current Sensor gives isolated DC voltage out put proportional to the AC or DC Current passing through. Sensors with higher Current ratings are in the offing.

Normally Current Sensors use resistive shunt or AC Current transformer. These two methods have limitations and disadvantages.

Systems new Current Sensor uses Hall effect to sense AC or DC Current. The sensor is totally isolated from main Current and not susceptible to external disturbances.

Current Sensors has linearity over the range exceeding one and half times. This gives an ability to withstand the overload without damaging Current sensor. Further more, electric burden is minimum as there is no resistive element in the series path or no transformer burden as in the case of AC Current transformer.

Current Sensors are not bulky and size does not increase with the Current rating. They are compatible with existing conventional measuring devices.
