Steam Turbine Shaft Tachometer Rotational Speed Monitor SZC-04FG

Product Introduction

SZC series wall-mounted rotational speed montior is an intelligent digital display instrument designed with advanced 51 series single-chip microprocessor chip. The use of automatic zero point correction, automatic temperature compensation and other technologies can ensure that the instrument works without drift for a long time, and the measurement accuracy is not affected by the ambient temperature; in addition to the use of resistance-capacitance filtering, digital filtering and automatic reset technology are also used to strengthen the anti-interference of the instrument.

Features

· Stable performance, long-term work without drift

· High reliability, measurement accuracy is not affected by ambient temperature

· Adopt digital filtering and automatic reset technology to enhance anti-interference

· Can distinguish and indicate forward and reverse

The SZC-04FG speed monitor is applicable for multiple functions as an advanced intelligent instrument:

☆ Steam Turbine and Turbine head speed monitoring
☆ Air separation /turbo expander speed monitoring
☆ Feed water pump rotation speed and reverse rotation speed monitoring
☆ Low speed unit - zero speed monitoring
☆ Motors - Keyphasor speed monitoring

The connection cable between the sensor and the instrument shall be shielded and grounded correctly.
The cable from the sensor to the instrument and the AC power cord or other strong current loop cables should not be placed in parallel for a long distance, especially in the same conduit;
When the sensor is installed on a high-power motor or generator, it is best to use a non-metallic bracket to insulate the sensor from the casing and reduce interference;
The instrument relay contact output can only be used to control the intermediate relay, and then the intermediate relay controls the load, instead of directly controlling the load by the internal relay of the instrument.
