Tachometer 7TE (7-TE, TE 7, 7te, 7TE, 7-TE, TE 7, 7TЄ, 7 TЄ 7 TЄ, 7-te, 7 te)
7TE tachometer is designed for remote measurement of the speed of parts of mechanisms and machines used in various sectors of the economy, in particular, the break-in-brake test bench of internal combustion engines, as well as to control the rotational speeds of separators, turbines, etc.
Technical characteristics of the devices tachometers 7TE:
Ambient air temperature - from -10 º C to +50 º C;
Maximum permissible error of the instrument tachometer 7TE given by:
± (α% ± M)
where α - the accuracy class tachometer, M - an error due to measurement resolution (smallest division of the price level);
Meter tachometer 7TE device designed to operate from a negative polarity signal of any shape or sinusoidal amplitude of 2V to 50V;
The converter provides an output signal amplitude negative polarity of at least 2V, with respect to pin 3;
Measuring range tachometer instrument 7TE must be from 2.0 rev / min to 99999ob/min;
Meter measurement range in the corresponding time of measurement should conform to Table 1;
Output frequency does not exceed 10000Gts and is given by:
F = (A ∙ K) / 60
where F - output frequency, A - a controlled speed of the shaft (r / min), K - number of teeth gear parts;
Minimum output frequency - 20Hz;
Tachometer 7TE consists of:
- Showing the device;
- The primary transmitter;
Meter tachometer can be used as a frequency;
Feeding the meter on AC, 50 Hz ± 1 Hz, 220V 22 V, 220-33B;
The electric power converter device is made from 7TE tachometer gauge circuits;
Sensitivity meter - no more than 12V ∙ A;
