JMX Series Meter Electronic Counter/Linear Velocimeter - JMX

JMX series electronic meter counter/linear velocimeter is provided with both functions of meter counting and displaying the linear velocity of material. As the JM series electronic meter counter, this series of instrument also adopts the single chip micro-processor as its main control component, has the merits of two sets of set-value for the meter counting control, high accuracy in the meter counting, digital display, soft-contact key operating, permanent data retention when power cut, strong anti-disturbance capability, pretty appearance, etc.

JMX series electronic meter counter/linear velocimeter can be used widely in the industries of packing, printing, textile, papermaking, petroleum, chemical engineering, metallurgy, etc, is able to operate for the meter counting display, control and displaying the linear velocity of the material in motion.

Mounting kind: panel mounting inserted kind
2 The part of meter counting
1 Selecting the kind of the control output (providing A,B two sets of setting function)
A set:
(1) When the meter counting value increases to its set value the contact output is produced and
the counting keeps on
(2) When the meter counting value increases to its set value, the contact output is produced and
the counting closes off.
(3) When the meter counting value increases to its set value, the meter counting is operating again
after its reset at once and the contact output is set free automatically when the mono-stable
delay is ended.
(4) When meter counting value reaches its setting, the meter counting closes off. It resets and the
contact output sets free automatically when the mono-stable delay is ended.
B set alarm control (corresponding to the alarm indicator on the surface panel, output produced
when the indicator is bright):
(1) When the meter counting value increases to its alarm value, the contact output is produced.
(2) When the meter counting value increases to its alarm value, the contact output is produced
and turns off after the mono-stable delay.
2 Contact capability of the control output: 3A/250VAC (for resistance load)
3 The range of the step length for the meter counting is 0.0001~1.0000m and resolving power
is 0.1mm. The step length is the length occupied by one pulse.
4 Holding/not holding data is selectable, the retention data time:10 years
5 Counting frequency: high speed is1000 times/s, low speed is30 times/s (signal duty ratio
is1:1) (selected by key pressing or by the terminals wiring)
6 Input signal and the frequency that ought to be selected
(1) Contact signal: For relay, distance switch, microswitch, the frequency of low speed (30times/s)
should be selected when the signal duty ratio is 1:1.
(2) Non-contact signal: For approach switch, photoelectric switch, etc, the frequency can
be selected of either high (1000 times/s) or low (30 times/s) speed according to requirement
when the signal duty ratio is 1:1.
(3) Pulse signal: For TTL circuit and so forth ( low level VL=0~1.3V, high level VH=4.5~30V). the
frequency can be selected of either high (1000 times/s) or low (30 times/s) speed according to
requirement.
7 Input impedance of signal: 2.4kΩ
8 Reset (clear to zero) kind:
(1) Reset with the reset (clear to zero) key on the surface panel
(2) Reset with the terminals (make short of the RST and COM pins)
(3) Local automatic reset at mono-stable delay: 0.1~9.9s is selectable .
9 The part of linear velocity counting
9.1 The input signal is taken from meter counting input signal, without control function.
9.2 Linear velocity is displayed in 4 digital bits.
9.3 The unit of display m/min or m/sec is able to be selected by key pressing.
10 Power supply: (1) 12~42VAC/DC (2)187~242VAC (3)85~264VAC
11 Power consumption:5W
12 Operating environment: temperature 0~50,relative humidity ≤85%
