Digital tachometer MICRO 9215

for boatspolycarbonateblack

Tachometer, this instrument calculates the speed value based on the frequency of the impulses coming from the external sensor proximity, pick-up, etc.). Impulses per revolution: 1-255 - Decimal point: 0, 1, 2, auto - Measurement update: 0.1, 0.25, 0.5, 1, 2, 4, 8 seconds. Unit of measurement conversion. Frequency meter, the instrument calculates the value of the input frequency of the pulses coming from the external sensor (proximity, pick-up, etc.). This value can also be converted in order to the desired unit of measurement. Decimal point: 0, 1, 2, auto - Measurement update: 0.1, 0.25, 0.5, 1, 2, 4, 8 seconds. Unit of measurement conversion. Totalisation, the pulses from the external sensor (proximity, pick-up, etc.) are totalised. Through the measurement conversion it is possible to make the each pulse correspond to desired increment. Decimal point: 0, 1, 2, auto - Unit of measurement conversion, Reset, Hold. Memory: the count remains stored for 10 years, even in the absence of power supply. Timer, when the "SIGNAL" input is closed, the timer counts the time until the input is returned to the open condition. Scale: 10 minutes, 10 hours, 1000 hours. Unit of measurement conversion, Reset, Hold. Memory: the count remains stored for 10 years, even in the absence of power supply Display: 5 digit 13mm Led • Sensors: Optical probe, Proximity, Pick-up, Contact sensor, encoder, etc. • Power supply to sensors: 12Vdc/30mA or 5Vdc/30mA • Wave form of input: sinusoidal min 100mVpp (a 1KHz), max 50Vac, square or opencollector (low = 0-1.5V high = 4-30V) • Input impedance (pick-up): 18K (signal): 2KΩ • Maximum frequency: in tachometer, frequency and totalisation 30KHz
