INT4 digital panel meter pricing



These digital panel meters and controllers are ideal for measuring the speed of objects such as vehicles or projectiles.

Velocity or speed meter




ADEPT-7 velocity meter

ADEPT-7 digital velocity / speed panel meter



cloud based data logger and trend analysis system




The basic model number for this application is:-

ADEPT-7-A-R-M-0-0-0-DI for 110/230VAC power
ADEPT-7-A-R-D-0-0-0-DI for 10-30VDC power

You can add output options such as alarm relays, analogue retransmission, serial data, networking etc, see below...

Application Note:
In applications where there may be muzzle blast, for example if your projectile is fired with explosive, you will need to ensure that the sensors do not detect the blast or you could get a false reading which shows the speed of the muzzle blast rather than of the projectile.

If that is not possible, we make a fast pulse latch module to ensure that only the projectile pulses are passed to the meter. See [here]
