The overall accuracy of the machine is better than 0.01%;

The display data, flow, speed, accumulative amount, load, time can be set to the same screen display built-in multifunctional regulator, can be directly in the instrument internal PID adjustment; Guided menu operation, the instrument has self-diagnosis, alarm prompt, pulse output, manual/automatic null balance and zero automatic tracking functions, and can realize the simulation or physical test error automatic correction;

With high and low belt speed alarm delay output and feed rate control deviation delay alarm output function; It has the output function of solid state relay with cumulative tonnage pulse signal, 0.01T, 0.1t optional;

With high and low limit alarm, fault self-diagnosis function

Test error can be selected as percentage or project value display

The system has the function of cumulative pulse output;

With a very reliable power failure protection of internal data function; Multiple isolation interfaces, extensible to achieve two-way communication (RS232/485), print output, current (flow 4~20mA) output, frequency output and other functions of data storage, battery to keep data up to 10 years;

Metal plate spray shell, waterproof, dust-proof, strong magnetic field interference.

With the speed measurement rolling simple using soft connection, real reflection belt speed measurement, accurate counting, not by repeated start and frequency conversion of high and low speed, even in mechanical vibration.

Self-excited vibration and electrical noise can also remain stable.

Accuracy: better than 0.025%;
