Overview

The KR939B3 fan safety monitor is a three channel, intelligent, disk mounted digital measurement and control instrument that can simultaneously display vibration temperature and liquid level.

Product Details

KR939B3 type fan safety monitorIt can also be used as a universal three channel digital display meter, connected with various probes or transmitters that output 4-20mA signals (such as vibration, temperature, pressure, differential pressure, liquid level, etc.), to form monitoring systems with different ranges and specifications.

KR939B3 type fan safety monitorFunction and technical parameters

4-20mA industrial standard signal input, 24V power supply provided in the table, no additional power supply required for on-site probes.
Three channel anti-interference remote transmission input, zero and range digital settings.
Three rows of four digit LED digital display, capable of simultaneously displaying the engineering measurement values of four input channels.
Three channel 'pre alarm' and 'parking alarm' two-level digital settings, with alarm mode selection.
Alarm relay electrical contact output, alarm hold function selection, convenient for forming parking interlock control.
Three channel analog signal isolation transmission output, freely connected to other instruments or computer data acquisition systems.
● Serial digital communication isolation interface, convenient for upper computer network management.
Internally, a single-chip microcomputer with * is used as the main control and fewer peripheral components are used to improve reliability.
● Adopting digital filtering WATCHDOG、 Technologies such as multiple redundancy, power down protection, and wide voltage switching power supply have a wide range of applications and high resistance.
Panel Instruction Manual
Basic error: 0.2% FS or ± 1 word
Display resolution: Three rows of four digit LED digital tubes
● Input signal: Standard 4-20mA current input
Alarm output: Two level dual group (normally open, normally closed) relay electrical contact output for 'pre alarm' and 'parking alarm', with a contact capacitance of AC220V/2A. The alarm values for each channel are independently set or disabled.
