Intelligent Rotational Speed and Hammer Monitor Protector

# Brief Introduction

This product adopts high-performance ARM processors to process circuit signals. Its ultra-high operating main frequency enables microsecond-level detection response to the ejection of trip plungers, and it is equipped with a reliable anti-interference automatic reset system.

The product displays turbine speed, and stores the trip speed, reset speed of emergency trip plungers, the maximum unit speed and corresponding real-time time inside the instrument. When the corresponding function key is pressed, it can display the operating speeds at the "ejection" and "reset" of the two trip plungers, as well as the maximum speed and real-time time. This product is equipped with analog speed signal output for use by other recorders, DCS systems and other equipment.

# Technical Features

- 3.5-inch touch screen for human-machine interface

- Dual-channel rotational speed measurement display; speed resolution accuracy: ±1 RPM; proportional progress bar display with 1% resolution accuracy; maximum measuring range: 65000 RPM

- Maximum measured speed memory function (including the real-time time when the maximum speed is reached)

- Detects ejection and reset actions of trip plungers, and records the rotational speeds and real-time time at ejection and reset
