Overview
The ethanol detector (infrared) is a low-power Modular design using MCU chip, with intelligent Sensor detection technology, overall flameproof (d) structure, and fixed Installation method. The standard configuration is LCDTFT high definition LCD display, three-wire system 4~ 20mA analog, RS485 digital and switching signal output, and provides customized products according to user requests. Outsignal put fine-tuning and other functions are also supported, which is convenient for system networking and maintenance.
Features
1. Adopt Customizable Range Intelligent Sensor, which guarantees the advantages of high Sensitivity, high accuracy, linear stability and fast Response of the detector;
2. The use of MCU chip highlights the low power consumption of the detector, safe and reliable performance, accurate data conversion, stable signal output, etc.;
3.4-20mA, RS485, switch and other signal output, easy access to PLC, DCS, DDC and other industrial control systems, can also be a single machine through the switch linkage fan, solenoid valve and other control equipment;
4. Support customized wireless signal transmission: Zigbee, LORA, 433M, 4G, WiFi, NB, GPRS, etc.;
5 point array high definition LCDTFT LCD screen, Chinese and English Operating interface can be switched;
6. The detector can be operated by remote control without opening the lid to perform function menu operations such as alarm value, zero adjustment, calibrating, reset, and modification of the address code;
7. Local integrated sound and light alarm indication, remote mobile phones, computers, monitoring rooms, third-party platforms and other alarm prompts can be realized through alarm control host or wireless signal, and infrared remote control can also be silenced with one click;
8. Aluminum alloy cast body explosion-proof shell, sturdy and durable;
9. Passed a variety of CMA, CNAS, CE, ROHS, SIL, UL, ECM safety and other international certifications;
10. Explosion-proof certificate grade: Ex db IIC T6 Gb; explosion-proof certificate number: SYEx23.04100.
Principle
The ethanol detector adopts infrared NDIR detection principle, and detects gas concentration through diffusion Sampling method to ensure detection accuracy and Response speed.
