Count and speed measuring instrument
|
|
Characteristic
1powerful functions are controlled by a set of keys on a panel, has excellent versatility.
2using single chip microcomputer analysis of data, better ability of anti-jamming than the foreign goods.
3can be widely used in online or offline measurement of cloth material, wire length, product count and control, is counting instrument in the field of a new generation of products on behalf of.

|
Main technical index
1: pulse signal input, photoelectric signal, contact signal
2 count rate: DC level to 150times / sec
3display: digital display, can be set to addition or subtraction counting
4count ratio: can be set from 0.01 to99.99
5: power on reset, reset manually reset, external reset, automatic reset, automatic reset
Methods:6 setting instrument panel touch switch set
7sensor supply output: DC12V, maximum current 30mA

| SP six double counting ( speed ) instrument |
|
Characteristic
1SCM data acquisition, analysis, digital filtering and control technology, the count ( speed ) table has strong anti-interference ability and high measuring accuracy.
In 2a large six digital tube display, the visibility is good.
3two input channels, can respectively detect the two object count value ( speed ).
4additional two channel count ( speed ) difference measurement, upper and lower limit speed alarm function.
|
|
|
Main technical parameters
1 input channel road:2 independent input
2signal form: passive contact or a level signal
The 3input pulse width: high level of effective width of pulse interval≥ 0.5ms,≥ 6ms
The 4highest count rate:1.66kHz/s
The 5 display range: 0～ 50000r/min
Measurement error:6≤ 0.1%F.S+1d
7: six digital tube display
In 8 settings: panel touch switch, no bad contact
9 channel switching speed of response: About 5S

Count ( speed ) table use
Count ( speed ) table can receive two pulse signals, signal by hardware after processing by the count ( speed ) table internal SCM software analysis, filtering, sent to the digital tube display. Count ( speed ) form a total of two display states, respectively, for automatic status and designated state, when the count ( speed ) table in automatic state, panel automatic indicator lights, with the channel indicator A or B lights, display window tour show A channel or B channel count ( speed ), conversion cycle of about 5seconds. The A indicator light, shows the A channel count ( speed ); B indicator light, shows the B channel count ( speed ).
|
| When the count ( speed ) table at point state, point indicator lights, with the channel A indicating lamp or lamp B, fixed-point display A channel or channel B count ( speed ). |
| Count ( speed ) table electric starting at point state, and the display of A channel count ( speed ), press the panel" function" key by" fixed-point show A channel" into" fixed-point show B channel", then " function " key by" fixed-point show B channel" into" automatic display A, B channel", a three state through the " function" key conversion, according to the actual need to select the display state. |
| Can also be based on user requirements will count ( speed ) table upgrade become two input pulse signal as an input pulse signal acquisition, such as100Hz standard square wave signal, count ( speed ) and real display only 3000, rather than6000 rpm, the speed measurement accuracy of some help. |
| When the input signal is greater than 50000, count ( speed ) table display"", says it has more than counting ( speed ) scale for the measurement of the upper limit of the range, should pay attention to system operation status. |
