Unipower HPL600 is a base unit in a monitoring system used for detection of tool breaks and tool bluntness on tools used in different types of tool machinery. The complete system is called „Tool Monitor System“ or TMS. When using the HPL600 a 0-20mA analogue signal is needed. This could be obtained from a power measuring device but a load or torque sensor could also be used.

It is possible to connect the HPL600 to a PC through a RS232 interface. TMSMon (supplied with the HPL600) is used for visualization and setting parameters etc. When supervision is based on power measurement the APM100 or APM380 are used. Both units are members of the Unipower Family. Typically the total power consumption of the spindle motor is measured.
