HB484FN/HB724FN Frequency meter/tachometer/linear speedometerDetailed product description：

HB484FN/HB724FN frequency meter/tachometer/linear speedometer

I. Overview
HB484/HB724 adopts a standard chassis, with an arc-shaped large display screen on the front panel. The display screen material is purple high filter transparent glass, exquisite and elegant.
Two rows of dual four digit ultra high brightness LED digital displays, with the upper row of digital tubes displaying measured values and the lower row of digital tubes displaying alarm set values.

2、 Characteristics
By selecting the product function number, the instrument can achieve frequency meter and tachometer functions
Switch quantity, level pulse, switch contact compatible input
Can be connected to external proximity switches, contact switches, photoelectric switches, encoders, etc
Magnification A, Magnification B, and decimal point can be set arbitrarily. Simple setting of magnification can measure linear velocity
Alarm setting value and functional parameter setting value will not be lost in case of power failure
The measured value reaches the set value, the relay is closed, and the instrument continues to measure
