Tachometer HZQW-03 is a high-precision speed monitoring device designed for steam turbines and is widely used in speed monitoring and protection of steam turbines. The device adopts high-performance microcomputer technology to realize intelligent digital display, can monitor the speed of the steam turbine in real time, and record relevant data when the emergency tripping device strikes out.

Product Features

• High-precision monitoring: can accurately measure the speed of the steam turbine with an accuracy better than ±1 r/min.

• Intelligent display: uses high-brightness LED display, high digital display accuracy, simple and intuitive operation.

• Internal storage function: can store the “strike” and “retract” states of the emergency tripping device striker, as well as the maximum speed of the unit.

• Strong anti-interference ability: equipped with a reliable anti-interference self-reset system to ensure stable operation in complex industrial environments.

• Multiple output options: provides 4-20mA standard current output, which is easy to integrate with various monitoring systems.

Technical parameters

• Measuring range: 0-99999 rpm, digital programming can be set arbitrarily.

• Display mode: High-brightness LED display.

• Power supply: AC85~265VAC wide range power supply.

• Output signal: 4-20mA standard current output.

• Working temperature: 0~60℃.

• Installation method: panel mounted or desktop mounted.

Tachometer HZQW-03 is widely used in speed monitoring and protection of steam turbine units. It not only plays an important role in the impactor action test before the new unit is put into operation, before each unit overhaul and grid connection, but also provides support in the impactor injection activity test after the unit has been running continuously for 2000 hours. In addition, its internal storage function is used to determine the action speed in the overspeed test, which greatly improves the accuracy and efficiency of the test.

In summary, Tachometer HZQW-03 is a high-performance and high-precision steam turbine speed monitoring device, suitable for a variety of industrial application scenarios, and can provide reliable data support and protection for the operation of steam turbines.
