SQK04T225-4 ,SQK04T200-4 Smart Tachometer Model:DZC-1
Function Description 1, to achieve intelligent processing: Alarm I value, II value can be set by the panel buttons arbitrarily, the panel button can adjust the range value, without potentiometer adjustment, convenient on-site debugging  4, a tooth number can be set by the panel buttons  5, alarm Delay adjustment range is 0.1~3 seconds to prevent false alarms caused by on-site interference. 5. With up/down detection function, at the same time cut off the alarm and shutdown output loop, which can effectively inhibit the instrument from false alarm. The proportional current output terminal for recording output technical indicators is a new type of local rotation speed measuring instrument. It has the trend of changing the speed intuitively in the form of analog meter display. The digital display method can accurately and intuitively display the current speed value. . It is suitable for on-site indication of the rotational speed of various rotating machines.

Overview
SQK04T225-4 and SQK04T200-4 intelligent tachometers are non-mechanical contact instruments. The meter head is a marine anti-vibration meter with high resistance to mechanical impact and can be widely used to display rotating speeds of rotating equipment such as steam turbines, diesel engines, and compressors. The table uses an advanced converter line and meter integrated structure, making the work more reliable and more accurate measurement. The watch has overspeed flash alarm and alarm linkage signal output function to make the tested device run more safely.
Uses are suitable for on-site monitoring of changes in rotational speed and speed during shutdown and start-up of rotating machinery.
Technical Parameters
Input signal: CS-1 reluctance speed sensor or pulse or sine wave with amplitude of 20mV to 30V.
Display mode: pointer display.
Measurement range: 0 to 1000 rpm, 0 to 4500 rpm, 0 to 10,000 rpm.
Overspeed alarm setting: 3200 rpm (factory default, changeable).
