Overview
HZS-C4C intelligent tachometer is an intelligent speed monitoring and protection instrument with ARM as the core. The monitoring instrument has the functions of speed monitoring, dual alarm setting point and analog current output. It is suitable for monitoring and protection of rotating machinery speed in electric power, petroleum, chemical and other industrial sectors.
Sensor signal input sensor input mode of smart tachometer: magnetoresistive sensor
Speed ​​plate gear teeth: 1~120 teeth
The SFSD-6 tachometer intelligent tachometer has two speed alarm limit values. As long as the measured speed exceeds the set alarm value or dangerous value, the alarm indicator or danger indicator on the front panel lights up, and the alarm relay or dangerous relay operates, and the switch signal is output. The alarm response time is 0.1S.
The main technical indicators show: 5-digit 0.8-inch LED digital display range: 1~99999rpm
Display accuracy: ±1rpm
Alarm, danger: Arbitrary setting alarm output in full scale: Normally open relay output contact capacity: 5A/250VAC 30VDC/5A
Current output: 4~20mA
RS485 communication: MODBUS-RTU protocol (optional)
Dimensions: 160 × 80 × 160mm
Opening size: 152+1×74+1mm

Function Description 1. Realize intelligent processing: alarm I value, II value can be arbitrarily set by panel button 2, panel button can adjust range value, no potentiometer adjustment, convenient on-site debugging 4, one tooth number can be set arbitrarily through panel button 5, alarm The delay adjustment range is 0.1~3 seconds to prevent false alarms caused by on-site interference. 5. It has upper and lower power detection functions. At the same time, it can cut off the alarm and stop the output circuit. It can effectively suppress the alarm of the instrument. 6. The rear panel has the value of the turn. Proportional current output terminal for recording output specifications

HZS-04M electronic analog tachometer (hereinafter referred to as tachometer) is a non-mechanical contact instrument that can be widely used to display the rotational speed of rotating equipment such as steam turbines, diesel engines and compressors. The structure of the watch is advanced, the measuring mechanism is the electromagnetic spring ball support, the rotating part has no friction, the work is reliable, and the mechanical impact resistance is high; and the advanced converter circuit and the head integrated structure make the work more reliable and more accurate. accurate. The watch also features an overspeed flash alarm and an alarm interlock signal output to make the device under test more secure. The connected reluctance speed measuring sensor forms a speed measuring system, which is mainly used for speed monitoring and alarming, and is generally installed directly on the head of the rotating machine, also called the head tachometer.
